3. Click the Enlarge button to increase the size of the text box by one font size.
4. Click the Reduce button to decrease the size of the text box by one font size.
5. Note that if the text box overlaps one of the borders of the window when enlarged, then the
command to enlarge the text box is ignored.
Pre de fined Shapes and Bitmaps
In addition to using the drawing tools to create your own graphics, EasyBuilder provides two types of predefined
graphics objects: shapes and bitmaps. These graphics objects are stored in libraries that come with EasyBuilder,
(more on libraries in the next section). Shapes and bitmaps are both used for the same purpose, to display a
predefined complex graphics object on the OIT screen. The difference between shapes and bitmaps is how they are
composed and stored.
Shapes are vector-based graphics which are stored in files that contain dimensional information about the shape.
Shapes are actually composed of several simpler graphics like the ones created by the drawing tools. Because of
this, they can usually be more easily modified than bitmaps.
Bitmaps are pixel-based graphics which are stored in files that contain information about each pixel to compose a
bitmap graphic. The pixel is the smallest possible detail that you can change on a screen. Because of this, although
bitmaps are more difficult to modify, they offer the most flexibility in customizing the graphic object.
In most cases, you won’t need to know the difference between a shape graphic and a bitmap graphic. You will base
your selection on what looks good. However, keep the following comparisons in mind.
