Initializes a new
ColorLevelCommandData class object with explicit parameters.
Syntax
Parameters
- minimumInput
- 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 and 0 to 65535 for 16-bit images. Any value greater than or equal to this will be considered a shadow and will be remapped to the value in MinimumOutput.
- maximumInput
- 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 and 0 to 65535 for 16-bit images. Any value greater than or equal to this will be considered a highlight and will be remapped to the value in MaximumOutput.
- minimumOutput
- 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 and 0 to 65535 for 16-bit images.
- maximumOutput
- 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 and 0 to 65535 for 16-bit images.
- gamma
- 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.
Example
Run the ColorLevelCommand on an image.
