imagepsbbox

(PHP 3 >= 3.0.9, PHP 4, PHP 5)

imagepsbbox -- Give the bounding box of a text rectangle using PostScript Type1 fonts

Description

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.

Parameters

text

font

Can be 1, 2, 3, 4, 5 for built-in fonts (where higher numbers corresponding to larger fonts) or any of your own font identifiers registered with imageloadfont().

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:

0left x-coordinate
1upper y-coordinate
2right x-coordinate
3lower y-coordinate

Notes

Note: This function is only available if PHP is compiled using --with-t1lib[=DIR].
