# imagecopymergegray

(PHP 4 >= 4.0.6, PHP 5)

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

## Descrição

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.

## Parâmetros

`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.

## Valores de retornado

Retorna `TRUE` em caso de sucesso ou `FALSE` em falhas.
