imagecopymerge

Description

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.

Parameters

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 palette images, except for ignoring alpha components, while it implements alpha transparency for true colour images.
