Usage

Use kirby 2 panel upload hook to process images on file upload.

kirby()->hook('panel.file.upload', function($file) {

  if ($file->type() == 'image') {
		mgf\ImageConverter::convert($file, array(
      'width' => 1024,
      'height' => 1024,
      'tosRGB' => true,
    ));
  }

});

Examples

Create a new ImageConverter Object by passing a Media Object and some params.

mgf\ImageConverter::convert($image);

This uses the default options, like below.

mgf\ImageConverter::convert($image, array(
  'width' => 1024,
  'height' => 1024,
  'tosRGB' => true,
));

This converts your image to a maximum size of 1024x1024 px and converts its colorspace to sRGB.

mgf\ImageConverter::convert($image, array(
  'destination' => '{name}_resized.{extension}',
));

This creates a new image in the same destination, as the original image and adds the suffix '_resized' to the filename.
