Refer to PostScript documentation about fonts and their measuring system if you have trouble understanding how this works.
Această funcție a fost ELIMINATĂ în PHP 7.0.0.
imageO resursă - imagine, întoarsă de una din funcțiile de creare a imaginilor, cum ar fi imagecreatetruecolor().
textThe text to be written.
font_indexA font resource, returned by imagepsloadfont().
size
size is expressed in pixels.
foregroundThe 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.
xx-coordinate for the lower-left corner of the first character.
yy-coordinate for the lower-left corner of the first character.
spaceAllows 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_stepsAllows 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.
This function returns an array containing the following elements:
| 0 | lower left x-coordinate |
| 1 | lower left y-coordinate |
| 2 | upper right x-coordinate |
| 3 | upper right y-coordinate |
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);
?>
