In this window you are asked to define the RGB channels for a new RGB image view. You are able to load defined RGB-Profiles, to create and store new or define only temporarily new profiles.
Red - Defines the mathematical expression for the red channel.
Green - Defines the mathematical expression for the green channel.
Blue - Defines the mathematical expression for the blue channel.
Use the to to edit the expression for the specific channel by using the expression editor.
|name||String||The name of the RGB-Profile, if given it is displayed instead of the file name.|
|internal||Boolean||The default value is false, if given and set to true it indicates that this RGB-Profile can not be deleted from the user interface (but does not prevent from overwriting the file).|
|red or r||String||The band math expression used to create the red channel. This entry is mandatory.|
|green or g||String||The band math expression used to create the green channel. This entry is mandatory.|
|blue or b||String||The band math expression used to create the blue channel. This entry is mandatory.|
Example: The following profile yields good RGB images from MERIS Level-1b data products. The linear-combinations for the red, green and blue components are based on the colour matching functions of the CIE 1931 color space.
name = MERIS L1b - High Quality internal = true red = log(1.0 + 0.35 * radiance_2 + \ 0.60 * radiance_5 + \ radiance_6 + \ 0.13 * radiance_7) green = log(1.0 + 0.21 * radiance_3 + \ 0.50 * radiance_4 + \ radiance_5 + \ 0.38 * radiance_6) blue = log(1.0 + 0.21 * radiance_1 + \ 1.75 * radiance_2 + \ 0.47 * radiance_3 + \ 0.16 * radiance_4)
