Convert
Use this API to change the format (PNG->JPEG, etc.) or resize images (for generating logo or thumbnails). These are not the only operations supported. In fact, the entire convert command options of ImageMagick can be passed through.
The APIs call ImageMagick 6.7.8-9 convert command. You can pass one file as the input, the convert options and the destination format, e.g png.
After this operation you will get a stagekey. You can download this staged file or attach it to a row. (Refer Files API)

The url contains the destination format {destformat}, e.g, png, gif, jpg. You must "multipart" post the payload with the source image file, and a form-data field called "convertopts", which contains the convert cli options.
