(PHP 4, PHP 5)

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

Descrizione

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.

Elenco dei parametri

image: Una risorsa immagine, restituita da una delle funzioni di creazione immagine, come imagecreatetruecolor().
text: The text to be written.
font: Può essere 1, 2, 3, 4, 5 per i font interni con codifica latin2 (dove numeri più alti corrispondono a font più grandi) o qualsiasi identificatore di font registrato con 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.

Valori restituiti

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

Note

Nota: Questa funzione è disponibile soltanto se il PHP è compilato utilizzando --with-t1lib[=DIR].
