(PHP 4, PHP 5)
imagepsbbox — Give the bounding box of a text rectangle using PostScript Type1 fonts
This function was REMOVED in PHP 7.0.0.
Description
array imagepsbbox ( string $text , resource $font , int $size )
array imagepsbbox ( string $text , resource $font , int $size , int $space , int $tightness , float $angle )
Gives the bounding box of a text rectangle using PostScript Type1 fonts.
The bounding box is calculated using information available from character metrics, and unfortunately tends to differ slightly from the results achieved by actually rasterizing the text. If the angle is 0 degrees, you can expect the text to need 1 pixel more to every direction.
Parameters
-
text
-
The text to be written.
-
font_index
-
A font resource, returned by imagepsloadfont().
-
size
-
size
is expressed in pixels. -
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.
Return Values
Returns an array containing the following elements:
0 | left x-coordinate |
1 | upper y-coordinate |
2 | right x-coordinate |
3 | lower y-coordinate |
Examples
Example #1 imagepsbbox() 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'); // Make a bounding box for the font $bbox = imagepsbbox('Sample text is simple', $font, 12); // Define our X and Y cordinates $x = ($bbox[2] / 2) - 10; $y = ($bbox[3] / 2) - 10; // Write the font to the image imagepstext($im, 'Sample text is simple', $font, 12, $black, $white, $x, $y); // Output and free memory header('Content-type: image/png'); imagepng($im); imagedestroy($im); ?>
