A.03 Lossless JPEG Transforms
Demonstrates how to apply lossless operations (rotate, flip, crop, update region and metadata) on JPEG files, without decoding/encoding JPEG data (therefore, avoiding image quality degradation).
B Filters and Transforms
B.05 Autorotate
Automatically rotates images based on EXIF orientation field. For JPEG images it uses lossless transform to prevent quality degradation.
F Metadata
F.02 Thumbnail from EXIF
