# imagepstext

(PHP 3>= 3.0.9, PHP 4 )

imagepstext -- To draw a text string over an image using PostScript Type1 fonts

## Description

array imagepstext ( resource image, string text, int font, int size, int foreground, int background, int x, int y [, int space [, int tightness [, float angle [, int antialias_steps]]]])

`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 PostScript 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.

`size` is expressed in pixels.

`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_steps` are optional.

> Notatka: Ta funkcja jest dostępna tylko jeśli PHP zostało skompilowane z dyrektywą `--enable-t1lib`.

This function returns an array containing the following elements:

0 | lower left x-coordinate
1 | lower left y-coordinate
2 | upper right x-coordinate
3 | upper right y-coordinate
