Saving shapes
Using the shapes menu it is possible to define a polygon shape
which can be saved. The shape is drawn as with a normal polygon,
by clicking on the points and double clicking to end the draw.
However instead of the shape being then drawn it is saved to a file
in a directory called "shapes". At any time the shape can then be
loaded and drawn using the current colors. As with any draw operation the
arrow buttons can be used to reposition the shape anywhere over the main image.
When the shape is loaded back into IconPainter you have the option
to draw the shape at the scale it was originally drawn or to scale it
to the new image dimension. Thus if the new image dimension is 64x64
but the shape was originally drawn on a 32x32 image then the shape
is scaled up to be double the size.
