imagecopymergegray
(PHP 4 >= 4.0.6)
imagecopymergegray -- Copy and merge part of an image with
gray scale
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 preserves the hue of the source by converting
the destination pixels to gray scale before the copy operation.
Note: This function was added in PHP 4.0.6
