(PHP 3 >= 3.0.9, PHP 4, PHP 5)

imagepstext -- Draws a text over an image using PostScript Type1 fonts

Opis

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

Draws 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.

Parametry

obraz

Zasób obrazu, zwrócony przez jedną z funkcji tworzących obrazy, taką jak imagecreatetruecolor().

text

The text to be written.

czcionka

Może przyjąć 1, 2, 3, 4, 5 dla wbudowanych czcionek (gdzie większy numer odpowiada większej czcionce) lub własny dowolny identyfikator czcionki zarejestrowany przez 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.

Zwracane wartości

This function returns an array containing the following elements:

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

Notatki

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