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 CR2 format uses EXIF file structure as the base. CR2 images contain a preview in the root IFD. This allows applications that do not support CR2 format, load the preview as a valid TIFF-EXIF image. Actual raw data is stored in the EXIF makernote tag. Raw data is encoded using JPEG lossless compression.
