PHP | imagecopymerge() Function

The imagecopymerge() function is an inbuilt function in PHP which is used to copy and merge the image into a single image. This function returns True on success or False on failure.

Syntax:

bool imagecopymerge ( $dst_image, $src_image, $dst_x, $dst_y, 
$src_x, $src_y, $src_w, $src_h, $pct )

Parameters: This function accepts nine parameters as mentioned above and described below:

  • $dst_image: This parameter is used to set destination image link resource.
  • $src_image: This parameter is used to set source image link resource.
  • $dst_x: This parameter is used to set x-coordinate of destination point.
  • $dst_y: This parameter is used to set y-coordinate of destination point.
  • $src_x: This parameter is used to set x-coordinate of source point.
  • $src_y: This parameter is used to set x-coordinate of source point.
  • $src_w: This parameter is used to set source width.
  • $src_h: This parameter is used to set source height.
  • $pct: The two images will be merged with the help of $pct variables. The range of pct is 0 to 100. If $pct = 0, then no action is taken and when $pct = 100 then this function behaves similar to imagecopy() function for pallete images, except ignoring the alpha components. It implements alpha transparency for true color images.

Return Value: This function returns True on success or False on failure.
