The LVLCLRINF structure contains color-leveling information for a specific color channel.

Member	Description
nMinInput	Value that specifies the image©s shadows to be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit, 0 to 65535 for 16-bit images, and from -32768 to 32767 for signed images. Any value greater than or equal to this will be considered a shadow and will be remapped to the value in nMinOutput.
nMaxInput	Value that specifies the image©s highlights to be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit, 0 to 65535 for 16-bit images, and from -32768 to 32767 for signed images. Any value greater than or equal to this will be considered a highlight and will be remapped to the value in nMaxOutput.
nMinOutput	Value that specifies the value to which the shadows will be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit, 0 to 65535 for 16-bit images, and from -32768 to 32767 for signed images.
nMaxOutput	Value that specifies the value to which the highlights will be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit, 0 to 65535 for 16-bit images, and from -32768 to 32767 for signed images.
uGamma	Value that represents the gamma value. This value is used to modify the midtones of the image. The value in this member is a 100 times the actual value. Therefore, if uGamma = 167 then the actual gamma value is 1.67. Likewise, if you want to use a gamma of 1.75, set this member to 175. The default value is DEFAULT_GAMMA, which is 100 (actual gamma value of 1.00) which does not change the gamma value of the image.

Comments

The value of the nMaxInput member must be greater than the value of the nMinInputValue member by at least 2.
