# imagecopymergegray

(PHP 4 >= 4.0.6, PHP 5)

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

### Description

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.

### Parameters

`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.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.
