imagecopymergegray
Descrizione
bool imagecopymergegray ( resource dst_im, resource src_im, int dst_x, int dst_y, int src_x, int src_y, int src_w, int src_h, int pct )imagecopymergegray() copy a part of src_im onto dst_im starting at the x,y coordinates src_x, src_y with a width of src_w and a height of src_h. The portion defined will be copied onto the x,y coordinates, dst_x and dst_y.
This function is identical to imagecopymerge() except that when merging it preserves the hue of the source by converting the destination pixels to gray scale before the copy operation.
Elenco dei parametri
- dst_im
Destination image link resource
- src_im
Source image link resource
- 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_w
Source width
- src_h
Source height
- 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, while it implements alpha transparency for true colour images.
