ImageGear Filter Control Parameters

See DCRAW Filter Control Parameters.


Pentax and Samsung digital cameras use this format for storing Raw images.

By default, ImageGear automatically reconstructs colors in raw images during loading. You can disable one or more stages in the automatic color reconstruction, and reconstruct the images programmatically by using ImageGear Processing API. Use filter control parameters to disable specific stages of color reconstruction.

Pentax/Samsung Raw format uses TIFF/EXIF file structure as the base. However, it is not fully compliant with TIFF, so it can't be processed by a regular TIFF viewer. Raw image is stored in the root TIFF IFD uncompressed, or using Huffman compression.
