Introduction

This chapter describes how to manage graphic objects and in particular how to rotate, distort, arrange, and position them on the slide. Though this chapter focuses on the shapes that can be created with the available tools in Impress, some of the techniques described in this chapter are also applicable to images imported into slides.

Drawing toolbar

The Drawing toolbar (Figure 1) contains the majority of the tools normally used to create graphic objects. If this toolbar is not visible, select View > Toolbars > Drawing from the Menu bar. By default, the Drawing toolbar is docked vertically at the left side of the Impress window.

Note

Your Drawing toolbar may differ from the one shown in Figure 1 as this depends on how many drawing tools have been placed on the toolbar. Right-click on an empty area of the Drawing toolbar, then select Visible Buttons from the context menu to display the available tools. From this dialog you can install and remove tools to and from the toolbar. See Appendix B, Toolbars for more information.

Creating lines and shapes

This section is an introduction to creating lines and shapes. For more information on working with lines and shapes, see the Draw Guide.

Drawing regular shapes

Regular shapes that are available on the Drawing toolbar (Figure 1) are Rectangle and Ellipse plus the following shapes

Some icons for regular shapes have a triangle to the right of the icon. Clicking on this triangle  opens a sub-toolbar giving access to several different types of regular shapes. The icons on the Drawing toolbar shows the last tool used for each of these regular shapes.

Drawing a regular shape is as follows:

1)  Select the required tool from the Drawing toolbar or from a sub-toolbar after clicking the triangle to the right of the icon.

2)  Place the cursor on the slide, then click and drag the mouse to define an enclosing rectangle.

3)  Release the mouse button and your shape is drawn on the slide.

4)  Press and hold the Shift key when creating a shape to maintain equal height and width. For example, when using the Rectangle or Ellipse tool to draw a square or a circle. Release the mouse cursor before releasing the Shift key.

5)  Press the Alt key to draw a shape from its center. Release the mouse cursor before releasing the Alt key.

6)  Press and hold the Shift And Alt keys when creating a shape to maintain equal height and width and draw the shape from the center. For example, when using the Rectangle or Ellipse tool to draw a square or a circle. Release the mouse cursor before releasing the Shift and Alt keys.

Regular shape adjustment

When creating shapes that are included in Impress, one or more dots may be displayed in a different color to the selection handles. These dots perform a different function according to the shape they are applied to and are listed below.

Basic Shapes

Refer to Figure 5  Figure 5 to identify the following shapes with adjustment dots.

Symbol Shapes

Refer to Figure 6  Figure 6 to identify the following shapes with adjustment dots.

Block Arrows

Refer to Figure 7  Figure 7 to identify the following shapes with adjustment dots.

Callouts

For all callouts (Figure 9) use the adjustment dots to change the length, position and angle of the pointer.

Stars and Banners

Refer to Figure 10 to identify the following shapes with adjustment dots.

Drawing curves, polygons and freeform lines

Curves, polygons and lines on the Drawing toolbar (Figure 1) have a triangle to the right of the icon. Clicking on this triangle opens a sub-toolbar giving access to several different types of curves, polygons and lines. The icons on the Drawing toolbar show the last tool used for each of these curves, polygons and lines. If a filled curve, filled polygon, or filled freeform line was selected, Impress draws the line connecting the last point to the start point and fills the inside area with the default color.

Curves

1)  Click the triangle ▼ to the right of Curves and Polygons on the Drawing toolbar to open the Curves and Polygons sub-toolbar (Figure 3).

2)  Select either Curve or Curve Filled.

3)  Place the cursor on the slide, then click and drag to create the starting point of your curve.

4)  Release the mouse button and drag the cursor to draw a curve on the slide, bending the line into a curve.

5)  Click to set the end point of the curve and fix the curve on the slide.

6)  Drag the cursor to continue drawing a straight line. Each mouse click sets a corner point and allows you to continue drawing another straight line from the corner point.

7)  Double-click to end the drawing of your curve.

8)  If Curve Filled was selected, Impress automatically fills the curve with the default color.

Note

Holding down the Shift key when drawing lines with the curve or polygon tools will restrict the angles between lines to 45 or 90 degrees.

Polygons and Polygons 45°

1)  Click the triangle ▼ to the right of Curves and Polygons on the Drawing toolbar to open the Curves and Polygons sub-toolbar.

2)  Select either Polygon, Polygon Filled, Polygon (45°) or Polygon Filled (45°).

3)  Place the cursor on the slide, then click and drag to draw the first line from the start point. Release the mouse button and a line between the first and second points is drawn.

4)  Move the cursor to draw the next line. Each mouse click sets a corner point and allows you to draw another line.

5)  Double-click to end the drawing of your polygon.

6)  If Polygon Filled or Polygon Filled (45°) was selected, Impress automatically fills the polygon with the default color.

Note

If Polygon (45°) or Polygon Filled (45°) were selected, the movement of the cursor and the angles between lines is restricted 45°.

Freeform lines

Using the Freeform Line or Freeform Line Filled tools is similar to drawing with a pencil on paper.

1)  Click the triangle ▼ to the right of Curves and Polygons on the Drawing toolbar to open the Curves and Polygons sub-toolbar (Figure 3).

2)  Select either Freeform Line or Freeform Line Filled.

3)  Click and drag the cursor to the line shape you require.

4)  When you finished drawing your freeform line, release the mouse button and the drawing is completed.

5)  If Freeform Line Filled was selected, Impress automatically fills the drawing between the start and end points with the default color.

Drawing lines and arrows

Straight lines

A straight line is the simplest element or object in Impress to create.

1)  Use one of the following methods to draw a line:

2)  Click at at the point where you want to start the line and drag the cursor.

3)  Release the mouse button at the point where you want to end the line. A selection handle appears at each end of the line. The selection handle at the starting point of the line is slightly larger than the end selection handle, as shown in Figure 16.

4)  Keep the Ctrl key pressed while drawing a line to enable the end of the line to snap to the nearest grid point.

5)  Keep the Shift key pressed while drawing a line to restrict the drawing angle of a line to multiple of 45 degrees.

6)  Keep the Alt key pressed while drawing a line to cause the line to extend outwards symmetrically in both directions from the start point. This lets you draw lines by starting from the middle of the line.

Figure 16: Line starting point

Image55

Arrows

Arrows are drawn like lines and are classified as a subgroup of lines, that is lines with arrowheads. Hovering the cursor over each type of arrow that is available will tell you the type of endings each tool will draw.

1)  Click the triangle on the right of Lines and Arrows on the Drawing toolbar and select the type of arrow from the sub-toolbar (Figure 2).

2)  Click at the point where you want to start the arrow, then drag the cursor. The arrowhead(s) is drawn at the end of the line when you release the mouse button.

3)  Keep the Ctrl key pressed while drawing an arrow to enable the end of the arrow to snap to the nearest grid point.

4)  Keep the Shift key pressed while drawing an arrow to restrict the drawing angle of an arrow to multiple of 45 degrees.

5)  Keep the Alt key pressed while drawing an arrow to cause the arrow to extend outwards symmetrically in both directions from the start point. This lets you draw arrows by starting from the middle of the arrow.

Grouping objects together

Grouping of objects is similar to putting objects into a container. You can move the objects as a group and apply global changes to the objects within the group. A group can always be undone and the objects that make up the group can always be manipulated separately.

This section gives only a brief introduction to grouping of objects. An example of grouping two objects together is shown in Figure 17. For more information on working with grouped objects, see the Draw Guide.

Figure 17: Grouping example

Image23

Temporary grouping

Temporary grouping is when several objects are selected. Any changes to object parameters that you carry out are applied to all of the objects within the temporary group. For example, you can rotate a temporary group of objects in its entirety.

A temporary group is created using one of the following methods:

To cancel a temporary grouping of objects, simply click outside of the selection handles displayed around the objects.

Grouping

To group objects together permanently:

1)  Objects are grouped using one of the following methods:

2)  With selection handles displayed, use one of the following methods to create a group of selected objects:

Editing or formatting groups

1)  Click on an object in the group to select the group. Any editing or formatting can then be carried out on all the objects within the group or on individual objects within the group.

2)  To edit an individual object within a group, you have to enter the group using one of the following methods:

3)  Select individual objects within the group for editing or formatting. An example of editing individual objects in a group is shown in Figure 18.

4)  When you have finished editing or formatting, use one of the following methods to exit the group and the whole group then becomes selected:

Figure 18: Example of editing in a group

Image24

Ungrouping

1)  Click on any one of the objects in the group to select the group.

2)  With selection handles displayed, use one of the following methods to ungroup a group of objects:

Tip

If you use group and ungroup commands often, or any other command, you can add commands to a toolbar so that they are readily available. See Chapter 11, Setting Up and Customizing Impress for more information on customizing the user interface.

Positioning and resizing graphic objects

Using a mouse

Positioning

For quick positioning of a graphic object on a slide, use the mouse as follows:

1)  Click on a graphic object or a group of objects to display the selection handles.

2)  Move the cursor over a selected graphic object until the cursor changes shape. The cursor shape depends on the computer setup and the computer operating system.

3)  Click and drag the graphic object to the desired position. During movement, a ghost image of the object appears to help with repositioning (Figure 19).

4)  Release the mouse button when the graphic object is in the desired position.

Figure 19: Example of moving objects with mouse

Image27

Note

You can also use the arrow keys to quickly move a selected object or group to a new position.

Tip

By default Impress snaps objects the grid when objects are being repositioned. If you need to position the object between two points of the grid, hold down the Ctrl key, then click on the object and move it to the desired position. Alternatively, you can turn this snap function off or modify the grid resolution by going to Tools > Options > LibreOffice Impress > Grid.

Resizing

For quick positioning of a graphic object on a slide, use the mouse as follow:

1)  Click on a graphic object or a group of objects to display the selection handles.

2)  Move the cursor over a selection handle.

3)  Click and drag the selection handle to resize the graphic object. During resizing, a ghost image of the object appears to help with resizing (Figure 20).

4)  To maintain the width to height ratio, hold down the Shift key before clicking and dragging on a selection handle. Remember to release the mouse button before releasing the Shift key.

5)  Release the mouse button when the graphic object is at the desired size.

Figure 20: Example of resizing objects with mouse

Figure 21: Position and Size dialog

Image21

Position and Size dialog

Positioning

For a more accurate placement of a graphic object on a slide, use the Position and Size dialog (Figure 21) as follows:

1)  Select a graphic object to display the selection handles and open the Position and Size dialog using one of the following methods:

2)  Click on the Position and Size tab.

3)  In the Position section, specify Position X (horizontal) and Position Y (vertical) position of the graphic object. The values represent the distance from the Base point selected on the right hand side of the dialog. The default selection for Base point is relative to the top left corner of the slide.

4)  If necessary, in the Protect section of the dialog, select the Position option to prevent the graphic object from being repositioned.

5)  Click OK to save the changes and to close the dialog.

Note

The units of measurement used in this dialog and other Impress dialogs are set in Tools > Options > LibreOffice Impress > General.

Resizing

1)  Select a graphic object to display the selection handles and open the Position and Size dialog using one of the following methods:

2)  Click on the Position and Size tab.

3)  In Size, select a Base point that you would like to use as an anchor when resizing the graphic object. The default selection of top left corner means that the top left corner of the object will not change position when resizing.

4)  To maintain the proportions between width and height, in the Size section select the Keep ratio option before changing the Width or Height. When Keep ratio is selected, changes to one dimension results in an automatic change to the other maintaining the ratio between object width and height.

5)  In the Size section, specify the Width and Height of the graphic object.

6)  If necessary, in the Protect section of the dialog, select the Size option to prevent the graphic object from being resized.

7)  Click OK to save the changes and to close the dialog.

Sidebar Position and Size section

Positioning

Use the Position and Size section in the Properties deck on the Sidebar to position a graphic object as follows:

1)  Select a graphic object to display the selection handles.

2)  Click on Properties in the Sidebar to open the Properties deck.

3)  Click on Position and Size section to open the section (Figure 22).

4)  Specify Position X (horizontal) and Position Y (vertical) position of the graphic object. The values represent the distance from the Base point that has been selected in the Position and Size dialog.

Figure 22: Position and Size section in Properties on Sidebar

5)  Press the Enter key to make the changes.

Resizing

Use the Position and Size section in the Properties deck on the Sidebar to resize a graphic object as follows:

1)  Select a graphic object to display the selection handles.

2)  Click on Properties in the Sidebar to open the Properties deck.

3)  Click on Position and Size section to open the section (Figure 22).

4)  To maintain the proportions between width and height, select the Keep ratio option before changing the Width or Height. When Keep ratio is selected, changes to one dimension results in an automatic change to the other maintaining the ratio between object width and height.

5)  Press the Enter key to make the changes.

Applying special effects

As well as the basic actions of moving and resizing an object, a number of special effects can also be applied to objects in Impress. This section describes how to rotate, flip, distort and setting an object in a circle.

Rotating graphic objects

Mouse rotation

1)  Click on a graphic object and the selection handles are displayed.

2)  On the Line and Filling toolbar, click on the triangle ▼ to the right of Transformations then click on Rotate on the sub-toolbar. The selection handles change shape and also change color as shown in Figure 23. A pivot point indicating the rotation center also appears in the center of the object.

Figure 23: Example of rotating objects

Image25

3)  Move the mouse over one of the corner handles and the mouse cursor shape will change.

4)  Click on a corner selection handle and move in the direction in which you want to rotate the graphic object. Only the corner selection handles are active for rotation.

5)  When satisfied with the rotation, release the mouse button.

6)  To change the rotation center of the object, click and drag the pivot point to the desired position before rotating. The pivot point can be moved to any position on the slide, even outside of the object boundaries.

7)  To restrict the rotation angles to multiples of 15 degrees, press and hold the Shift key while rotating the graphic. This is useful for rotating pictures through a right angle, for example from portrait to landscape. Remember to release the Shift key before releasing the mouse button.

Position and Size dialog rotation

Instead of rotating a graphic object manually, use the Rotation page of the Position and Size dialog (Figure 24) to accurately rotate an object.

1)  Select a graphic object to display the selection handles and open the Position and Size dialog using one of the following methods:

2)  Click on the Rotation tab to open the Rotation page.

3)  In Pivot Point and, if necessary, enter a measurement for Position X and Position Y to move the position of the pivot point. The default position of the pivot point is the center of the object. Alternatively, select a pivot point from one of the 9 positions in Default settings.

4)  In Rotation Angle, enter the degree amount for rotation in the Angle text box. Alternatively, in Default settings, click on the rotation angle indicator and drag it to a new angle. The angle of rotation is displayed in the Angle text box.

5)  Click OK to save your changes and to close the dialog.

Sidebar rotation

Use the Position and Size section in the Properties deck on the Sidebar to rotate a graphic object as follows:

1)  Select a graphic object to display the selection handles.

2)  Click on Properties in the Sidebar to open the Properties deck.

3)  Click on Position and Size section to open the section (Figure 22).

4)  In Rotation, enter the degree amount for rotation in the text box or click on the rotation angle indicator and drag it to a new angle. The angle of rotation is displayed in the Rotation text box.

5)  Press the Enter key to make the changes.

Flipping objects

Quick flipping

1)  Click on a graphic object to display the selection handles.

2)  Quickly flip a selected object so it faces the other direction using one of the following methods:

Flip tool

To change the position and angle that an object flips over, the Flip tool on the Transformations toolbar has to be used as shown in Figure 25.

1)  Click on a graphic object and the selection handles will show.

Figure 25: Example of using Flip tool

Image29

Figure 26: Transformations toolbar

Image30

2)  Go to View > Toolbars > Transformations to open the Transformations toolbar (Figure 26).

3)  Click on Flip on the Transformations toolbar and an axis of symmetry appears as a dashed line through the center of the object. The object will be flipped about this axis of symmetry.

4)  Click and drag the axis of symmetry to a new position, or position the cursor in one of the circles at each end of the axis of symmetry and drag with your mouse cursor to change the angle.

5)  Place the cursor over one of the selection handles for the object.

6)  Click and drag the cursor across the axis of symmetry to flip the object. The new position of the object is shown faintly until the mouse is released.

7)  Release the mouse button and the object will appear flipped over. Angle and position of the flip will depend on the angle and position of the axis of symmetry.

Note

Press the Shift key while moving the axis of symmetry to rotate it in 45-degree increments.

Mirror copies

Impress does not include a mirror command. However, mirroring an object can be emulated by flipping the object:

1)  Select the object you want to make a mirror copy of and copy the object to the clipboard.

2)  Flip the object using one of the methods in “Quick flipping”  above, then move the flipped object to one side.

3)  Click on an empty area of the page to deselect the object.

4)  Paste from the clipboard to put a copy of the object into your slide.

5)  Select both images, then right-click and select Alignment from the context menu and select the type of alignment you want to use. Top, Center, or Bottom if you are creating a horizontal mirror copy. Left, Centered, or Right if you are creating a vertical mirror copy.

Distorting images

Three tools on the Transformations toolbar (Figure 26) allow an object to be distorted.

Note

When using these tools, an object has to be transformed to a curve before distorting. Transforming an object into a curve cannot be reversed and can only be undone by using the Undo function.

Distort tool

1)  Select an object and click on the Distort icon on the Transformations toolbar.

2)  Click Yes to convert the object to a curve. If the object is already a curve, this dialog does not appear.

3)  Click and drag a corner selection handle to distort the object using the opposite corner selection handle as an anchor point for the distortion (Figure 27).

4)  Click and drag the vertical selection handles to distort the object using the opposite vertical side as an anchor point for the distortion.

5)  Click and drag the horizontal selection handles to distort the object using the opposite horizontal side as an anchor point for the distortion.

Image32

Set in Circle (perspective) tool

1)  Select an object and click on the Set in Circle (perspective) icon in the Transformations toolbar.

2)  Click Yes to convert the object to a curve. If the object is already a curve, this dialog does not appear.

3)  Click and drag one of the selection handles to give a pseudo 3D perspective using the opposite side as an anchor point (Figure 28). A ghosted image appears as you drag to give an indication of how the resulting object will look.

Set to circle (slant) tool

1)  Select an object and click on the Set to circle (slant) tool in the Transformations toolbar.

2)  Click Yes to convert the object to a curve. If the object is already a curve, this dialog does not appear.

3)  Click and drag one of the selection handles to give a pseudo 3D perspective using the opposite side as an anchor point (Figure 29). A ghosted image appears as you drag to give an indication of how the resulting object will look.

Figure 29: Example of Set in circle (slant)

Image33

Aligning objects

Use the alignment tools in LibreOffice to adjust the relative position of an object compared to another object. These alignment tools are only active if two or more objects are selected. The alignment options are as follows:

Select the objects you want to align and use one of the following methods to access the align options:

Using grid or snap functions

In Impress, you can also position objects accurately and consistently using grid points, snap points and lines, object frames, individual points on objects, or page edges. This function is known as Snap. It allows you to position an object in exactly the same place on multiple slides.

It is easier to use snap functions at the highest practical zoom value for your presentation. You can use two different snap functions at the same time. For example, snapping to a guide line and the slide edge. It is recommended to activate only those snap functions that you really need.

Figure 30: Grid dialog

Image34

Configuring grid and snap

To configure the grid and snap in your presentation, go to Tools > Options > LibreOffice Impress > Grid on the Menu bar to display the Grid dialog (Figure 30).

Figure 31: Options toolbar

Image35

The grid and snap functions can also be displayed and switched on or off using one of the following methods:

Snap to grid

Using Snap to Grid

Use the Snap to Grid function to move an object exactly onto a grid point in a slide. This function can be switched on and off using one of the following methods:

Figure 32: Application Colors dialog

Image36

Displaying grid

Display or turn off the grid in a presentation using one of the following methods:

Changing color of grid points

By default and depending on your display and computer setup, the grid points are gray and are not always easy to see. To change the color of the grid points, go to Tools > Options > LibreOffice > Application Colors to open the Application Colors dialog (Figure 32). In the Drawing/Presentation section, select a more suitable color for the grid from the drop-down list.

Snap points and lines

Unlike the grid, snap lines and snap points are inserted when you want to position an object to a specific position on a slide. Snap lines can either be horizontally or vertically and appear as dashed lines. Snap points appear as small crosses with dashed lines. Snap points and snap lines do not appear in printed output.

Inserting snap points and lines

To insert a snap point or line use one of the following methods to open the New Snap Object dialog (Figure 33):

The options available in the New Snap Object dialog are as follows:

Figure 33: New Snap Object dialog

Image37

Tip

When positioning snap lines, it is useful to display the rulers by selecting View > Rulers on the Menu bar. Drag a snap line directly onto a slide by clicking on the horizontal or vertical ruler and dragging a snap line onto the slide.

Displaying snap points and lines

Display or turn off snap points and lines in a presentation using one of the following methods:

Editing snap points and lines

Edit a snap point as follows:

1)  Right-click on a snap point and select Edit Snap Point from the context menu to open the Edit Snap Point dialog (Figure 34).

2)  Enter new X and Y coordinate settings for the snap point and click OK. Alternatively, drag the snap point to a new position on the slide.

Figure 34: Edit Snap Point dialog

Image38

Figure 35: Edit Snap Line dialog

Image39

Edit a snap line as follows:

1)  Right-click on a snap line and select Edit Snap Line from the context menu to open the Edit Snap Line dialog (Figure 35).

2)  Enter a new X coordinate setting for vertical snap lines or a new Y coordinate setting for horizontal snap lines and click OK. Alternatively, drag a snap line to a new position on the slide.

Deleting snap points and lines

1)  Right-click on a snap point or line.

2)  Select Delete Snap Point or Delete Snap Line from the context menu.

Note

Clicking on Delete in the Edit Snap Point or Edit Snap Line dialog also deletes a snap point or snap line.

Configuring snap range

To configure the snap range of when an object snaps to a position.

1)  Go to Tools > Options > LibreOffice Impress > Grid on the Menu bar to open the Grid dialog (Figure 30).

2)  Enter the number of pixels to set the proximity of when the object snaps into position in the Snap range text box. The default setting is 5 pixels.

3)  Click OK to set the new snap range and close the dialog.

Using Helplines

Helplines are a function in Impress to help position objects and can be displayed while an object is being moved. They extend from the edges of the object to the rulers at the top and left side of your workspace and do not have a snap function (Figure 36).

Use one of the following methods to display helplines while moving an object:

Figure 36: Example of using helplines

Image41

Arranging objects

Impress organizes objects in a stack so that the objects on the top level of the stack cover the objects on lower levels if any overlapping occurs. The stack level of each object can be changed by arranging shapes on a slide.

Select an object or objects and use one of the following methods to change the stack level:

The options available for arranging the object stack level on a slide are as follow:

Connectors and glue points

Connectors are lines that can be anchored to glue points and by default are positioned on the border of an object. When an object with a connector attached is moved or resized, the connector automatically adjusts to the change. When creating a flowchart, organization chart, schematics, or diagrams, it is highly recommended to use connectors instead of simple lines.

Connectors

When a connector is drawn or selected, Impress displays selection handles that are different to the selection handles for normal lines. The termination points of a connector are square at the start of a connector and round at the end of a connector. The selection handles on a connector line are used to change the routing of a connector where applicable.

Impress offers a wide variety of predefined connectors, which differ in the termination shape (none, arrow, custom) and in the way the connector is drawn (straight, line, curved).

Drawing connectors

1)  Click on the triangle to right of Connectors on the Drawing toolbar (Figure 1) to open the Connectors sub-toolbar (Figure 4). The Connectors icon shown on the Drawing toolbar depends on the last connector that had been previously used.

2)  Select the type of connector required from the Connectors sub-toolbar.

3)  Move the mouse cursor over one of the objects to be connected and small crosses appear around the object edges, normally in the same position as selection handles. These crosses are the glue points to which a connector can be attached (Figure 38).

4)  Click on the required glue point to attach one end of the connector, then hold the mouse button down and drag the connector to another object.

5)  When the cursor is over the glue point of the target object release the mouse button and the connector is drawn.

6)  The selection handles that appear on the connector are used to adjust the path of the connector so that the connector does not cover another object in its path.

Figure 38: Example of connector glue points

Image44

Connector types

The full range of predefined connectors can be accessed by clicking on the triangle on the title bar of the Connectors sub-toolbar and selecting Visible Buttons (Figure 4). The connectors available on the toolbar are indicated either by the connector icon being highlighted or by a check mark against the name.

Connectors fall into four type groups:

Formatting connectors

To detach or reposition a connector, click and drag either end of the connector line to a different location.

To change the connector route between objects avoiding any objects on the route, click on a control point on the connector line and drag it to a new position. In Figure 39, the control points are shown as small squares.

To change a connector type, right-click on the connector and select Connector from the context menu to open the Connector dialog (Figure 40). Use this dialog to select a connector type and change the connector properties.

Image43

Note

You cannot swap the ends of the connector using the Connector dialog, that is start point becomes the end point and the end point becomes the start point. To swap the ends of a connector, you have to draw a new connector in the opposite direction.

Glue points

Glue points are not the same as the selection handles of an object. The selection handles are for moving or changing the shape of an object. Glue points are used to fix or glue a connector to an object so that when the object moves, the connector stays fixed to that object.

All objects have glue points, which are not normally displayed and only become visible when Connectors on the Drawing toolbar is selected. Note that the Connectors icon changes shape depending on the last connector tool used.

To add, customize or delete glue points on an object, open the Gluepoints toolbar (Figure 41) using one of the following methods:

Glue point types

When the Gluepoints toolbar (Figure 41) opens, only the six tools on the left of the toolbar are active. The remaining six tools on the right of the toolbar only become active when Glue Point Relative is deselected.

Figure 41: Gluepoints toolbar

Image45

The following briefly describes the function of each tool on the Gluepoints toolbar:

The following six tools only become active when the Glue Point Relative tool is deselected.

Note

Each glue point you have added can have only one horizontal position and one vertical position. Only one of the horizontal position tools and one of the vertical position tools can be selected and used at any one time.

Adding glue points

By default, most objects normally have four glue points. Add additional glue points to an object as follows:

1)  Make sure no objects are selected and use one of the following methods to open the Gluepoints toolbar:

2)  Select the object, then click on Insert Glue Point on the Gluepoints toolbar Alternatively, right click on a glue point you have previously inserted and select Insert Glue Point from the context menu.

3)  Move your cursor to a position where you want the glue point on an object and click to insert the glue point.

4)  Select the type of glue point required from the options on the Gluepoints toolbar.

5)  To move a glue point to another position, click on the glue point and drag it to its new position.

Tip

When adding, moving or customizing glue points, it is recommended to use the zoom function to make it easier to work with glue points. Also, glue points snap to the grid making it easier to position a glue point.

Customizing glue points

Only glue points that have been added to an object can be customized. The default glue points included with an object cannot be customized.

Customize the exit direction for an added glue point as follow:

1)  Make sure no objects are selected and use one of the following methods to open the Gluepoints toolbar:

2)  Double-click on a glue point that you have added to select the glue point for customization.

3)  Select an exit direction you want to use for the connector from the options available on the Gluepoints toolbar, or right click on the glue point and select the exit direction from the context menu.

Customize the horizontal and vertical positioning for the added glue point as follow:

1)  Make sure no objects are selected and use one of the following methods to open the Gluepoints toolbar:

2)  Double-click on a glue point that you have added to select the glue point for customization.

3)  Click on Glue Point Relative on the Gluepoints toolbar to deselect this tool, or right-click on the glue point and deselect Glue Point Relative from the context menu.

4)  Select the horizontal and vertical positioning tools you want to use for the glue point. Only one horizontal positioning tool and one vertical positioning tool can be used at any one time.

Deleting glue points

Only glue points that have been added to an object can be deleted. The default glue points included with an object cannot be deleted.

1)  Select the glue point you have previously added and now want to delete.

2)  Press the Delete key or go to Edit > Cut on the Menu bar.

Working with 3D objects

Although Impress offers advanced functions to manipulate 3D objects, this guide describes only the 3D settings applicable to an object. For additional information on how to use advanced 3D effects such as geometry and shading, refer to the Draw Guide.

3D objects can be created in Impress in any of the following ways:

Figure 42: 3D-Settings toolbar

Image46

The options available on the 3D-Settings toolbar are as follows:

Note

Most of the Fontwork shapes (see “Fontwork”  below) have 3D properties and can be manipulated with the 3D-Settings toolbar.

Converting objects

You can convert an object into a different type using one of the following methods:

The conversion options are as follows:

Note

In most cases the conversion to a different type does not immediately produce visible results.

Tip

To Curve, To Polygon, To 3D, and To 3D Rotation Object can be added to the Drawing toolbar as additional tools by right-clicking in an empty area on the toolbar and selecting Visible Buttons. See Appendix B, Toolbars for more information.

Interaction with objects

You can associate an object to an action that is performed when it is clicked and this is called an interaction:

1)  Select the object for interaction.

2)  Open the Interaction dialog (Figure 43) using one of the following methods:

3)  Select the interaction from the available options in Action at mouse click: and any parameters (if applicable) that maybe available. The Interaction dialog changes depending on the type of interaction selected. The interactions and parameters are explained in Table 1.

Fontwork

With Fontwork you can create graphical text art objects to make your work more attractive. There are many different settings for text art objects (line, area, position, size, and more), so you have a large choice. For more information about Fontwork, see the Getting Started Guide.

Fontwork is also available with the Writer, Calc, and Draw modules of LibreOffice, but you will notice small differences in the way that each component displays it.

Creating Fontwork

1)  Click on Fontwork on the Standard toolbar or go to Insert > Fontwork on the Menu bar to open the Fontwork Gallery dialog (Figure 44).

2)  Select a Fontwork style from the dialog and click OK. The selected Fontwork appears on your slide and the dialog closes.

3)  Double-click on the word Fontwork to switch on editing mode.

4)  Type your own text to replace the word Fontwork and your text appears over the word Fontwork as shown in Figure 45.

5)  Press the Esc key or click outside the selected area and your text replaces the word Fontwork.

Fontwork toolbar

The Fontwork toolbar (Figure 46) becomes visible and active on the workspace when you select a Fontwork object. If the toolbar is not visible, go to View > Toolbars > Fontwork on the Menu bar. The Fontwork toolbar contains the following tools:

Modifying Fontwork

It is possible to treat Fontwork text as an object and apply all the formatting that has been described in this chapter. Assign line properties only to Fontwork which does not have a 3D effect, otherwise the changes will not be visible. You can also modify some of the Fontwork shapes just as you modify the angles of trapezoid and parallelogram basic shapes by moving the dot that is displayed along with the selection handles.

Animations

Animated slide transitions can be added between slides to give your presentation a more professional look when you change to the next slide (see Chapter 9, Slide Shows for more information on transitions). However, Impress also allows you to add animations onto the slides to create more interest in your presentation.

An animation consists of a sequence of images or objects called frames that are displayed in succession when the animation runs. Each frame may contain one or more objects. For example, make bullet points appear one by one; make pictures, shapes or other objects appear singly or as a group onto a slide. Animations can be controlled using the keyboard, mouse click, or automatically in a timed sequence.

Note

Anything that can be placed onto a slide is an object. For example, an object can be an image, clip art drawing, text, and so on.

Tip

Animations can look great in a presentation, but overuse of animations can make a good presentation into a poor presentation. Always use discretion when adding animations to your presentation.

Animated images

You can animate drawing objects, text objects, and graphic objects (images) on your slides to make your presentation more interesting. LibreOffice Impress provides has a simple animation editor where you can create animation images (frames) by assembling objects from your slide. The animation effect is achieved by rotating through the static frames that you create.

Creating animated image

1)  Select an object or group of objects that you want to include in your animation and go to Insert > Media > Animated Image to open the Animation dialog (Figure 52).

2)  Add an object or objects using one of the following methods:

3)  In Animation Group, select Bitmap object.

4)  Enter the frame (image) number in the Image Number box for the image you want to setup.

5)  In Duration specify the duration time in seconds for displaying a frame.

6)  Specify the number of times a frame is displayed in the animation sequence in Loop Count. This is called looping.

7)  Repeat Steps 4 thru 6 for each image or object used for the animated image.

8)  Click on Create and the animated image appears centrally on the slide.

Note

If the image to be copied consists of several objects, you can choose to treat each object as a separate frame. In this case, click on Apply Objects Individually. Remember that each object will be centered in the animation.
