| rectUnionRect |
(Rectangle rect1, Number x, Number y, Number width, Number height) |
|
| |
Returns a rectangle that represents the union of
rect1
and
rect2.
The second rectangle can also be supplied by giving its
width,
height,
and coordinates of its upper left corner
(x,y).

| Example: |
The program,
import yoix.*.*;
JFrame frame = {
Color background = Color.black;
Rectangle rect1;
Rectangle rect2;
Rectangle rect3;
paint() {
rect1.x = 36;
rect1.y = 72;
rect1.width = 4.0*72.0;
rect1.height = 2.0*71.0;
rect2.x = root.size.width - 5.0*72.0;
rect2.y = root.size.height - 3.5*72.0;
rect2.width = 4.0*72.0;
rect2.height = 2.0*72.0;
rect3 = rectUnionRect(rect1, rect2);
graphics {
gsave();
setrgbcolor(Color.red);
rectfill(rect1);
setrgbcolor(Color.blue);
rectfill(rect2);
if (rect3 != NULL) {
setrgbcolor(Color.white);
rectstroke(rect3);
}
grestore();
}
}
};
frame.visible = TRUE;
fills two rectangles and then draws the outline of the rectangle that
represents their union.
The rectangles are drawn at fixed positions relative to the upper
left and lower right corners of the frame, so you can change the
union by resizing the frame.
