The Better JPEG library allows for rapid development of applications capable of lossless / nearly lossless processing of JPEG images. Lossless modification of JPEG images is now standard for applications performing such image manipulations as rotation, flip, crop or partial image modifications (adding text or dates, EXIF imprint, watermark, red-eye reduction, hot-pixel removal, retouching, and so on). The Better JPEG editor is a good example of an application that utilizes the Better JPEG library.
The library is available as a DLL module for Win32 and provides a high level programming interface, which makes it easy to use from a variety of development environments, and programming languages, such as C, C++, VB, Delphi, etc.
The Better JPEG library features: • Lossless JPEG Transformations - Rotation, Flip • Lossless JPEG Crop • Lossless JPEG Canvas enlargement • Partial JPEG modification without full recompression. The client application simply modifies a bitmap; the library automatically identifies the changes and recompresses changed areas • Embedded Undo/Redo support • EXIF support (access to parameters, thumbnail refresh) • Compression optimization
