int $src_x, int $src_y, int $dst_w,
int $dst_h, int $src_w, int $src_h )
Parameters:This function accepts ten parameters as mentioned above and described below:
- $dst_image: It specifies the destination image resource.
- $src_image: It specifies the source image resource.

Below given programs illustrate the imagecopyresized() function in PHP:
Program 1 (Resize image to 1.5 times of its width and height):
<?php
$percent = 1.5;
$newwidth = $width * $percent ;
$newheight = $height * $percent ;
$thumb = imagecreatetruecolor( $newwidth , $newheight );
imagecopyresized( $thumb , $source , 0, 0, 0, 0, $newwidth , $newheight , $width , $height );
header( 'Content-Type: image/jpeg' );
imagejpeg( $thumb );
?>
|
Output:
Program 2 (Resize image with a fixed width and height):
<?php
$width = 150;
$height = 150;
$image_p = imagecreatetruecolor( $width , $height );
imagecopyresized( $image_p , $image , 0, 0, 0, 0, $width , $height , $width_orig , $height_orig );
header( 'Content-Type: image/jpeg' );
imagejpeg( $image_p , null, 100);
?>
