(Rectangle rect) |
typedict.Graphics |
| rectstroke |
(Number x, Number y, Number width, Number height [, double alpha]) |
|
| |
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 strokes the resulting path on
drawable
using
foreground
and the optional
alpha
argument, which should be a number between
0.0
and
1.0,
as the alpha value.
The values assigned to
linewidth,
linecap,
linejoin,
miterlimit,
dasharray,
dashphase,
and
CTM
when
rectstroke
is called are used to select the pixels that are actually painted as the
rectangle is drawn.
rectstroke
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();
linewidth = 6;
translate(drawable.size.width/2, drawable.size.height/2);
rotate(atan2(size.height, size.width)*180.0/PI);
setrgbcolor(1, 0, 0);
rectstroke(-36, -36, 72, 72);
grestore();
}
}
};
f.visible = TRUE;
defines a paint function in a frame that strokes a red square that
stays close to the center of the frame and keeps two sides parallel
to the line connecting the frame's upper left and lower right corners.
