imagecreate
(PHP 4, PHP 5)
imagecreate — Create a new palette based image
Descrizione
$width
, int $height
)imagecreate() returns an image identifier representing a blank image of specified size.
In general, we recommend the use of imagecreatetruecolor() instead of imagecreate() so that image processing occurs on the highest quality image possible. If you want to output a palette image, then imagetruecolortopalette() should be called immediately before saving the image with imagepng() or imagegif().

Valori restituiti
