자원.
-
text
-
The text to be written.
-
font_index
-
A font resource, returned by imagepsloadfont().
-
size
-
size
is expressed in pixels.
-
foreground
-
The color in which the text will be painted.
-
background
-
The color to which the text will try to fade in with antialiasing.
No pixels with the color background
are
actually painted, so the background image does not need to be of solid
color.
-
x
-
x-coordinate for the lower-left corner of the first character.
-
y
-
y-coordinate for the lower-left corner of the first character.
-
space
-
Allows you to change the default value of a space in a font. This
amount is added to the normal value and can also be negative.
Expressed in character space units, where 1 unit is 1/1000th of an
em-square.
-
tightness
-
tightness
allows you to control the amount
of white space between characters. This amount is added to the
normal character width and can also be negative.
Expressed in character space units, where 1 unit is 1/1000th of an
em-square.
-
angle
-
angle
is in degrees.
-
antialias_steps
-
Allows you to control the number of colours used for antialiasing
text. Allowed values are 4 and 16. The higher value is recommended
for text sizes lower than 20, where the effect in text quality is
quite visible. With bigger sizes, use 4. It's less computationally
intensive.

Example #1 imagepstext() usage
<?php
// Create image handle
$im = imagecreatetruecolor(200, 200);
// Allocate colors
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
// Load the PostScript Font
$font = imagepsloadfont('font.pfm');
// Write the font to the image
imagepstext($im, 'Sample text is simple', $font, 12, $black, $white, 50, 50);
// Output and free memory
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
