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
fontCan 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:
