Description
int
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.
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().
This function is identical to imagecopymerge() except
that when merging it preservese the hue of the source by converting
the destination pixels to gray scale before the copy operation.
Poznßmka: This function was added in PHP 4.0.6
