How to make requests through this service

The Mobify image resizing service will shrink, change the format of and potentially recompress to a different quality for jpeg output, images requested through it.

Requests are of the form:

http://ir0.mobify.com/(project-<slug>)/(cb<cache breaker>)/<format><quality>/<maximum width>/<maximum height>/<url>

Where:

slug

is a string that represents the project's slug.

cache breaker

is an integer (usually random) used to break the cache.

format

is one of jpg, png, webp or q. If set, the output will be in the format selected, regardless of input format with the special case of q representing the original format and is intended for allowing the setting of quality only. Otherwise the image will be output in its original format if it is a jpg or png, or as a png if it is a gif.

quality

is an integer between 1 and 100 inclusive. This parameter only has effect if the formats jpg or webp has been specified or the orignal image is a jpeg or webp image and the format q has been specified. The service will recompress the image with the specified quality.

maximum width

is an integer between 1 and 4000, inclusive. The image will be proportionally scaled to have a maximum width no greater than the specified number of pixels. If only one numerical resizing parameter is passed, it will be used as a maximum width.

maximum height

is an integer between 1 and 4000, inclusive. The image will be proportionally scaled to have a maximum height no greater than the specified number of pixels.

url

is an http or https URL of a jpeg, png or gif image of dimensions of no more than 4000x4000 pixels to be resized by the service.

All parameters, other than url are optional.
