(PHP 4 >= 4.0.6, PHP 5)

imagecopymergegray -- Copy and merge part of an image with gray scale

Opis

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.

Parametry

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.

Zwracane wartości

Zwraca TRUE w przypadku sukcesu, FALSE w przypadku porażki.
