Image Resize

Resize an image and output as either JPEG or PNG.

This API uses a high-grade and adaptive image scaling algorithm and will preserve the aspect ratio of the original image. You can also convert many image formats automatically, we currently support source images in these formats: GIF, ICO, JPEG, PNG, TIFF.
