| translatepath |
(Number dx, Number dy) |
typedict.Path |
| |
Translates this path by the displacement
(dx, dy)
where
dx
and
dy
are distances in user space that are transformed into device space
to obtain the horizontal and vertical displacements that are applied
to every point in this path.
We can talk about horizontal and vertical translation because the coordinates
of the points in a path are always assumed to be stored in device space,
which closely matches the device-dependent coordinate system that Java
assigns to your screen.

| Example: |
The program,
import yoix.*.*;
Path p1;
Path p2;
p1 { // "named block"
moveto(0, 0);
rlineto(72, 0);
rlineto(0, 36);
closepath();
rmoveto(72, 36);
}
p2 { // "named block"
moveto(0, 0);
rlineto(72, -36);
}
JFrame f = {
Color background = Color.white;
paint(Rectangle r) {
graphics { // "named block"
moveto(72, 72);
appendpath(p1);
appendpath(p2);
appendpath(p1);
translatepath(72, 144);
gsave();
setrgbcolor(0, 0, 1);
fill();
grestore();
setrgbcolor(1, 0, 0);
stroke();
}
}
};
f.visible = TRUE;
defines a paint function in a frame that fills and strokes a path that
is built from two separate paths using
appendpath
and
translatepath.
