imagepsbbox
(PHP 3 >= 3.0.9, PHP 4, PHP 5)
imagepsbbox -- Give the bounding box of a text rectangle using PostScript Type1 fontsOpis
array imagepsbbox ( string text, int 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.
