Description

The imagecopymerge of Image for PHP copy and merge part of an image.

Syntax

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
): bool

Parameters

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.

Return

Returns true on success or false on failure.
