(PHP 3 = 3.0.9, PHP 4 )
Size is expressed in
pixels.
Foreground is the
color in which the text will be painted. Background is the color to which the
text will try to fade in with antialiasing. No pixels with
the color background are
actually painted, so the background image does not need to be
of solid color.
The coordinates given by
x, y will define
the origin (or reference point) of the first character
(roughly the lower-left corner of the character). This is
different from the imagestring(), where x,
y define the upper-right corner of the first
character. Refer to PostScipt documentation about fonts and
their measuring system if you have trouble understanding how
this works.
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.
Antialias_steps allows
you to control the number of colours used for antialiasing
text. Allowed values are 4 and 16. The higher value is
recommended for text sizes lower than 20, where the effect in
text quality is quite visible. With bigger sizes, use 4. It's
less computationally intensive.
Parameters space and
tightness are expressed in
character space units, where 1 unit is 1/1000th of an
em-square.
Parameters space, tightness, angle and
antialias are optional.
This function returns an array containing the following
elements:
