Thumbnail weirdness: resizing incorrectly

#1

hi all,

right, i'm using the image library and resize to generate thumbnails, and it seems that if the image is smaller then the given width and height, that it resizes it bigger.

I tried putting in some code to check, but it's just prooven buggy.

Code:
public function generate($source, $output, $width, $height) {
            
            $size = getimagesize($source);
            if($size[0] < $width && $size[1] < $height) {
                copy($source, $output);
                return;
            }
            
            $config['image_library'] = 'GD2';
            //$config['library_path'] = '/usr/bin/X11';
            $config['source_image'] = $source;
            $config['maintain_ratio'] = TRUE;
            $config['create_thumb'] = false;
            $config['new_image'] = $output;
            $config['quality'] = 100;
            $config['width'] = (int)$width;
            $config['height'] = (int)$height;
            
            $this->base->image_lib->initialize($config);
            if(!$this->base->image_lib->resize())
                die($this->base->image_lib->display_errors());
            
        }

I have tried using an if/or on the width/height of the image. But I had an image that was wider then the given width, but shorter then the given height. This in turn copied the image.

Basically i need to resize images whilst maintaining the ratio, to the size i've given, but if the image is already smaller then the height or width then I would like it to handle it correctly.

Has anyone had this problem before?

Thank you all in advance!

Gavin
