Question

I have an image with dimensions 1440 X 500.

I need to crop this image on the left at 200px and right at 200px. That is the new image must have dimensions of 1040 X 500.

I am trying this

$original_w = 1440;
$original_h = 500;

$new_w = 1040;
$new_h = 500;

$new_img = imagecreatetruecolor( $new_w, $new_h);
imagecopyresampled($new_img, $original_img, 200, 0, 200, 0, $new_w, $new_h, $original_w, $original_h);

I have not obtained a desirable result, please help, what I am doing wrong?

Answer 1

Reading PHP doc, you’re using imagecopyresampled wrong :

imagecopyresampled ( 
   resource $dst_image , 
   resource $src_image , 
   int $dst_x , 
   int $dst_y , 
   int $src_x , 
   int $src_y , 
   int $dst_w , 
   int $dst_h , 
   int $src_w , 
   int $src_h 
)

So :

$original_w = 1440;
$original_h = 500;

$new_w = 1040;
$new_h = 500;

$new_img = imagecreatetruecolor( $new_w, $new_h);
imagecopyresampled($new_img, $original_img, 0, 0, 200, 0, $new_w, $new_h, $new_w, $new_h);

Copying the 1040*500 box from (200,0) coords to the new image, at (0,0) coords.
