This document helps you understand circle crop.
Operation Scenarios
ZOS supports cropping an image into an inscribed circle. You can configure parameters to crop images stored in ZOS into an inscribed circle, with non-circular areas filled with transparency or white.
Constraints and Restrictions
For images that support transparency channels (such as PNG), non-circular areas are filled with transparency after cropping. For images that do not support transparency channels (such as JPG), non-circular areas are filled with white after cropping.
For general limitations on the source format, file size, and image resolution, see Image Processing Overview - Image Restrictions.
For regions supporting circle crop, see Product Capability Map.
