Transforms
rect,
or the rectangle that has
(x, y)
as its upper left corner and
width
and
height
as its dimensions, using
CTM
and then fills the resulting path on
drawable
by painting its interior using
drawable's
background
color and the optional
alpha
argument, which should be a number between
0.0
and
1.0,
as the alpha value.
recterase
makes no use of or changes to the current
path.

| Example: |
The program,
import yoix.*.*;
JFrame f = {
Color background = Color.white;
paint(Rectangle r) {
graphics { // "named block"
gsave();
translate(drawable.size.width/2, drawable.size.height/2);
scale(1, drawable.size.height/drawable.size.width);
arc(0, 0, 144, 0, 360);
setrgbcolor(1, 0, 0);
fill();
recterase(-36, -36, 72, 72);
grestore();
}
}
};
f.visible = TRUE;
defines a paint function in a frame that fills a red ellipse that has a
small rectangle cut out of the center of the ellipse.
Do you understand why the ellispe and the rectangle change when the
frame is resized?
