There are functions for color, size, shape, attributes, and modes of various objects. You can type in one color and draw lines and shapes in another. Viewports can be scaled and modified.
Coordinate functions can be in convenient units.
You can draw lines, arcs, polylines, beziers, circles, pies, rectangles, and other figures. These may be empty or filled with color. Bitmaps can be inserted. Fonts can be changed. The program for this month's meeting will demonstrate only a few of these possibilities.
