Tone Correction
| ImageGear Professional v18.2 > User Guide > Using ImageGear > Working with Digital Camera RAW formats > Reconstructing Camera Raw Images with Image Processing API > Tone Correction |
In order to adjust image tone (contrast/brightness curve), set the "APPLY_TONE_CORRECTION" filter option to False. This will tell ImageGear to skip the tone correction step. The application can create a Tone correction LUT using IGProcessingCtl Control.BuildCameraToneLUT Method, or build its own Tone LUT. In order to convert the image to the standard sRGB color space, an additional sRGB Gamma LUT must be applied. Use IGProcessingCtl Control.BuildSRGBGammaLUT Method to build sRGB Gamma LUT.
Use IGProcessingCtl Control.TransformWithLUTs Method to apply a LUT to the image.
The APPLY_TONE_CORRECTION parameter only has effect if both APPLY_COLORSPACE_CONVERSION and RECONSTRUCT_COLORS options are True.
