Copy and merge part of an image

Descrizione

imagecopymerge(
    GdImage $dst_image,
    GdImage $src_image,
    int $dst_x,
    int $dst_y,
    int $src_x,
    int $src_y,
    int $src_width,
    int $src_height,
    int $pct
): true

Copy a part of src_image onto dst_image starting at the x,y coordinates src_x, src_y with a width of src_width and a height of src_height. The portion defined will be copied onto the x,y coordinates, dst_x and dst_y.

Elenco dei parametri

dst_image: Risorsa link dell'immagine di destinazione
src_image: Risorsa link dell'immagine originale
dst_x: x-coordinate of destination point.
dst_y: y-coordinate of destination point.
src_x: x-coordinate of source point.
src_y: y-coordinate of source point.
src_width: Larghezza dell'originale.
src_height: Altezza dell'originale.
pct: The two images will be merged according to pct which can range from 0 to 100. When pct = 0, no action is taken, when 100 this function behaves identically to imagecopy() for pallete images, except for ignoring alpha components, while it implements alpha transparency for true colour images.
