Aspect ratio crop

Crop by aspect ratio or aspect ratio range

Sets target aspect ratio or aspect ratio range when cropping. Aspect ratios can be set as decimal values (1.778) or ratios (16:9).

aspect_ratio=AR | ar=AR

aspect_ratio=AR1,AR2 | ar=AR1,AR2

Crop and resize

If you provide only one dimension parameter (width or height) and aspect_ratio, the other dimension will be calcualted. If you include both width and height in the URL, aspect_ratio is ignored.


Original aspect ratio (3:2 or 1.5): /docs/car1.jpg?w=400

Crop without resize

If you provide only aspect_ratio and no dimensions (width or height), the image will be cropped without resizing.



Original aspect ratio (1.323): /docs/frog.png

Cropped to 3:2 (1.5): /docs/frog.png?aspect_ratio=3:2

Aspect ratio range

You can spcify a range of aspect ratio, for example aspect_ratio=4:3,16:9. Images which fall within this range, will not be cropped. Useful to avoid very wide ot very tall images by cropping them to the closest aspect ratio.


Original aspect ratio 1.5: /docs/car1.jpg?w=400

Aspect ratio range 1.5..2 (no crop needed): /docs/car1.jpg?w=400&aspect_ratio=1.5,2.0

Original aspect ratio 2.25:1 (2.25): /docs/kids.jpg?w=400

Aspect ratio range 3:2..2:1 (1.5..2): /docs/kids.jpg?w=400&aspect_ratio=3:2,2:1
