Comments

This is one of the two main formats that Canon digital cameras use to store 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.

Canon CRW format uses CIFF file structure as the base. CIFF file format is similar to TIFF in many aspects, but is not compatible with it. Raw data is encoded using Canon proprietary compression.
