Note: (*) Where destHeight and destWidth are defined in the template then, in most cases, Crop Service will resize the image to match these properties. If the selection is smaller than destHeight or destWidth then a warning is shown, but the selection may still be used. Note that if destWidth*destHeight < 10,000 pixels 2, then the image is not resized, but the selection may still be used.

All edited images from both Crop Tool and Crop Service are saved as Portable Network Graphics (PNG) images, and saved with the same image and person information as the original image, if that exists. The new file is given a default prefix crop_paste<random characters>_. Images with alpha or key values are preserved.

Crop Service caches cropped images on file on the Pilot Data Server, as well as on the Viz Engine.

Crop Tool saves the cropped image to the VOS-file-share, and from there it is handled the same as any other VOS image.
