same, since you must finish drawing the triangle on the same point
you started. This form of draw statement gives you the power to
DRAW almost any geometric shape, such as trapezoids, parallelo
grams and polygons.
The DRAW statement also has a third form.
You can DRAW one point at a time by specifying the starting X and Y
values as follows:
150 DRAW 1,150,175
This statement DRAWs a dot below the CIRCLE.
As you can see, the DRAW statement has versatile features which
give you the capability to create shapes, lines points and a virtually
unlimited number of computer drawings on your screen.
PAINTing The DRAW statement allows you to outline
Outlined areas on the screen. What if you want to fill
Areas—The areas within your drawn lines? That's where the
PAINT Command PAI NT statement comes i n. The PAI NT state
ment does exactly what the name implies—it
fills in.orJPAINTs, outlined areas with color. Just
as a painter covers a canvas with paint, the
PAINT statement covers the areas of the screen
with any of the 16 colors. For example, type:
160 PAINT 1,150,97
Line 160 PAINTS the circle you have drawn in line 60. The PAINT
statement fills a defined area until a specified boundary is detected
according to which source is indicated. When the Commodore 128
finishes PAINTing, it leaves the pixel cursor at the point where PAINT
ing began (in this case, at point 150,97).
Here are two more PAINT statements:
180 PAINT 1,50,25
200 PAINT 1,225,125
Line 180 PAINTS the triangle and line 200 PAINTS the empty box.
IMPORTANT PAINTING TIP: If you choose a starting point in
your PAINT statement which is already colored from the same
source, the Commodore 128 will not PAINT that area. You must
choose a starting point which is entirely inside the boundary of
the shape you want to PAINT The starting point cannot be on
