Pie chart-the second type is the drawing program, such as freehand, illustrator or corel draw. the images they produce are
more likely to be line drawings or graphs, made up of lines and rectangles, or round shapes of various sorts. the
graphs, pie charts, business charts and other business drawings which are produced by spreadsheets are this type
of image. drawing images are made up of lots of different objects, where each object is a line, rectangle, or other
shape. these objects require much less storage than bitmaps. to store a large red rectangle, for example, all that is
required is a description of where the corners are, how thick the line is, and what colours the line and the inside of
the rectangle are. if the same rectangle were stored as a bitmap, you would need to store information about every
point within it.
as you build up a drawing, you can go back to objects you have already drawn and move them around, change their
size, line thickness, colour, and so on. in contrast to this, when you add something new to a bitmap, you erase
whatever is under the new part. so paintings are good for fine detail and subtle shadings of colour, while drawings
are good for simpler graphical shapes where you want to be able to change and manipulate objects. it is also
possible to create a detailed image in a paint program and copy it into a draw program where it can be combined with
other objects.
for completeness, there are also two other types of graphics program, which are mostly used by design
