PHP | imagecopymerge() Function
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 ( $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 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 x-coordinate of the 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 similarly to imagecopy() function for palette 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. The below programs illustrate the imagecopymerge() function in PHP.
Program 1: Input Source Image:
Input Destination Image:
php
<?php // Create image instances $dest = imagecreatefromgif( 'https://media.w3wiki.net/wp-content/uploads/animateImages.gif' ); $src = imagecreatefromgif( 'https://media.w3wiki.net/wp-content/uploads/slider.gif' ); // Copy and merge imagecopymerge( $dest , $src , 10, 10, 0, 0, 500, 200, 75); // Output and free from memory header( 'Content-Type: image/gif' ); imagegif( $dest ); imagedestroy( $dest ); imagedestroy( $src ); ?> |
Output:
Program 2: Input Source Image:
Input Destination Image:
php
<?php // Create image instances $dest = imagecreatefrompng( 'https://media.w3wiki.net/wp-content/uploads/w3wiki-9.png' ); $src = imagecreatefrompng( 'https://media.w3wiki.net/wp-content/uploads/col1.png' ); // Copy and merge imagecopymerge( $dest , $src , 10, 10, 0, 0, 500, 200, 75); // Output and free from memory header( 'Content-Type: image/png' ); imagegif( $dest ); imagedestroy( $dest ); imagedestroy( $src ); ?> |
