Question

I am using the following code snippet in order to crop a image?

   function crop($width,$height) {
       $new_image = imagecreatetruecolor($width, $height);
       imagecopyresampled($new_image, $this->image, 0, 0, 0, 0, $this->getWidth(), $this->getHeight(), $width, $height );
       $this->image = $new_image;
   }

Here, $this->image is the original image $this->getWidth() and $this->getHeight() holds the original dimensions of the picture, where as $width and $height, is the crop area.

But for some reason, the crop image is resized(we can almost say it is resized).

How to fix this?

Answer 1

Well, the problem is giving the source dimensions. Giving the dimensions of entire image will re size instead of cropping.

This should solve the problem

   function crop($width,$height) {
       $new_image = imagecreatetruecolor($width, $height);
       imagecopyresampled($new_image, $this->image, 0, 0, 0, 0, $width, $height, $width, $height );
       $this->image = $new_image;
   }
