imagecreate

(PHP 4, PHP 5, PHP 7, PHP 8)

imagecreateCreate a new palette based image

Descrizione

imagecreate(int $width, int $height): GdImage|false

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().

Elenco dei parametri

width

The image width.

height

The image height.

Valori restituiti

Restituisce un identificatore di risorsa immagine, false in caso di errore.
