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.
This function returns an array containing the following
