The commands available are documented into the following categories:
Note: the order of QueryString parameters does not affect output. The are evaluated in the most efficient operations regardless of order.
width=100&height=100&mode=max&scale=down ensures the image is downscaled to 100x100 or less, but does not upscale the image if it is already smaller than that. Aspect ratio is maintained.
width=200&height=200&mode=max&scale=both ensures the image is downscaled or upscaled to fit within 200x200, maintaining aspect ratio.
width=200&height=200&mode=pad&scale=both ensures the image is downscaled or upscaled to fit within 200x200, maintaining aspect ratio, then is padded to make the result always 200x200.
width=300&height=300&mode=crop&scale=both ensures the image is downscaled or upscaled to fit around 300x300, then minimally cropped to meet the aspect ratio. scale=both ensures the image is upscaled if smaller so the result is always 300x300.
