| ashow |
(Number ax, Number ay, String str [, double alpha]) |
typedict.Graphics |
| |
Draws the characters in
str
on
drawable
starting at the current point, which is adjusted as the characters in
str
are printed.
Character outlines come from
font
and are painted using
foreground
and the optional
alpha
argument, which should be a number between
0.0
and
1.0,
as the alpha value.
Omitting
alpha
or supplying a value of
1.0
are equivalent.
ashow
aborts with a
nocurrentpoint
error if
path
is empty.
ashow
always processes the characters in
str
individually, even when
ax
and
ay
are zero, and is used to make identical adjustments to the position of
every character.
The first character in
str
is placed at the current point, which is adjusted horizontally by the
width of that character plus
ax
and vertically by
ay
before the second character is printed.
The process stops after the last character in
str
is printed.

| Example: |
The program,
import yoix.*.*;
JFrame f = {
Graphics graphics = {
String font = "Lucida-bold-24";
Color foreground = Color.red;
};
paint(Rectangle r) {
String text = "hello, world";
graphics { // "named block"
gsave();
rectclip(r);
translate(drawable.size.width/2, drawable.size.height/2);
moveto(-stringwidth(text)/2, 0);
ashow(0, -3, text);
grestore();
}
}
};
f.visible = TRUE;
defines a paint function in a frame that draws a string of characters
near the center of the frame using
ashow.
