PHP | imagecopymerge() Function (original) (raw)

Last Updated : 11 Jul, 2025

The **imagecopymerge() function is an inbuilt function in PHP that 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 ( dstimage,dst_image, dsti​mage,src_image, dstx,dst_x, dstx​,dst_y, srcx,src_x, srcx​,src_y, srcw,src_w, srcw​,src_h, $pct )

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

• ****$dst_image:** This parameter is used to set the destination image link resource.
• ****$src_image:** This parameter is used to set the source image link resource.
• ****$dst_x:** This parameter is used to set the x-coordinate of the destination point.
• ****$dst_y:** This parameter is used to set the y-coordinate of the destination point.
• ****$src_x:** This parameter is used to set the x-coordinate of the source point.
• ****$src_y:** This parameter is used to set the y-coordinate of the source point.
• ****$src_w:** This parameter is used to set the source width.
• ****$src_h:** This parameter is used to set the 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,thennoactionistaken,andwhenpct = 0, then no action is taken, and when pct=0,thennoactionistaken,andwhenpct = 100, then this function behaves similarly to the imagecopy() function for palette images, except ignoring the alpha components. It implements alpha transparency for true color images.
