3. The Table category lists the standard colours or the colours that are used most often. However, if you need a colour or shade that is not available in the list, go ahead and create it! To define a custom colour:
a. Click the standard colour closest to your needs, and specify the RGB ratio to change its tone and hue.
Draw provides you two options to define a colour. You can specify the colour in the RGB or CMYK ratio. For CMYK, click RGB and then select CMYK from the options.
b. If you want to add a new custom colour to the available list, type its name in the Name box, specify the RGB ratio and click Add. The standard list under the Table category displays the new colour.
Nice to Know:
Every colour is specified by a combination of the three primary colours, Red, Green and Blue, hence the notation RGB.
c. Click OK to apply the change.
Editing a Gradient Fill
A gradient is a smooth transition between two different colours or shades of the same colour, which you can apply to a drawing object. To edit the gradient fill of an object:
In the Drawing area, select the object you want to edit and click the Area button on the Line and Fill toolbar. The Area dialogue box opens. Click the Gradients tab, select a gradient from the gradient list and click OK to apply the change to the object.
Mention that by using the Area dialogue box, students can also add or modify the other properties of objects such as using a shadow on an object, increasing or decreasing transparency, crosshatching the object or adding their own bitmap images as the area fill of the object.
Draw provides you the following options to insert text in the Drawing area:
• The Text tool on the Drawing toolbar: You can create a text frame anywhere in the drawing area, and you can work with this text box like you do with any other object.
• Callouts next to the object: You can use this when you want to relate the text to the object. Click the Callouts tool on the Drawing toolbar.
• Text superimposed on a drawing object: Double-click the object. A text box opens. Type the necessary text in it.
The following graphic displays various options for inserting text relevant to an object in the Drawing area:
Apart from offering the basic drawing tools, Draw provides scope for you to add some visual effects to your drawings. Cross-Fading
The cross-fading feature in Draw transforms one shape into another. The result is a new group of objects, including the start and end objects and the intermediate shapes.
1. Create two objects of different shapes in the drawing area and select them.
2. On the Edit menu, click the Cross-fading option to display the Cross-fading dialogue box.
3. In the Cross-fading dialogue box, select the number of incremental objects between the ends. Retain the default selection for smoother transition, and click OK to display the result in the drawing area.
You can vary the order of the objects by changing their arrangement in the drawing area.
Draw provides many more features and tools. For more information on the detailed features of Draw and other OpenOffice.org applications, refer the students to http://documentation.openoffice.org/.
