Imagemagick thumbnail generation with php - using -crop

Question

Long ago I created a small library for resizing images using imagemagick through system(...) because I did not feel that the build-in imagemagick functions for PHP

Answer 1

I tell one suggestion you can try it,

I saw the Image link I think the conditions are not checked correctly.

you have checked condition [(width/height) > (maxWidth/maxHeight)] Instead of check

if(width == height) { } elseif(width > height) { } else(width < height){ }

Check this condition and according to this condition crop the image and resize.

Thank you

Answer 2

The solution was the following:

    if ($width/$height > $this->maxWidth/$this->maxHeight) {
      // then resize to the new height...
                $command .= ' -resize "x'.$this->maxHeight.'"';

                // ... and get the middle part of the new image
                // what is the resized width?
                $resized_w = ($this->maxHeight/$height) * $width;

                // crop
                $command .= ' -crop "'.$this->maxWidth.'x'.$this->maxHeight.'+'.round(($resized_w - $this->maxWidth)/2).'+0" +repage';
            } else {
              $command .= ' -resize "' . $this->maxWidth . 'x"';
              $resized_h = ($this->maxWidth/$width) * $height;

                // crop
                $command .= ' -crop "'.$this->maxWidth.'x'.$this->maxHeight.
                             '+0+'.round(($resized_h - $this->maxHeight)/2).'" +repage';
            }
