(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])

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.

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.

angle is in degrees.

Parameters space and

tightness are expressed in character space

units, where 1 unit is 1/1000th of an em-square.

Parameters space,

tightness, and angle

are optional.

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.
