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_
Nota: This function was added in PHP 4_0_6
