Seznam parametrů
image
An image resource, returned by one of the image creation functions, such as imagecreatetruecolor().
text
The text to be written.
font
Can 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.foreground
The 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.x
x-coordinate for the lower-left corner of the first character
y
y-coordinate for the lower-left corner of the first character
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.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.
