imagepstext -- Draws a text over an image using PostScript Type1 fontsDraws a text on an image using PostScript Type1 fonts.
Refer to PostScript documentation about fonts and their measuring system if you have trouble understanding how this works.
imageAn image resource, returned by one of the image creation functions, such as imagecreatetruecolor().
textThe text to be written.
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.
      
foregroundThe color in which the text will be painted.
background
       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.
      
xx-coordinate for the lower-left corner of the first character
yy-coordinate for the lower-left corner of the first character
spaceAllows 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.
      
antialias_stepsAllows 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.
