Nice easy to use extension if you want to crop the original image file and let the editor choose the aspect ratio.
But we have often the use case to only have a cropped version with a special aspect ration for example in lineviews or for gallerythumbnails and for the full view the original aspect ratio.
For this usecase we have a crop extension. We define which aspect ratio we want for this a class_image. The editor can't choose the aspect ratio (but it could be possible). We only store the crop information for the original image and have a new crop filter for image.ini. Then we can choose on which imagealias we want to use the crop or not.
