Name

ccdrgb - create composite RGB color images from multiple input images

Synopsis

ccdrgb [parameter=value]

Description

No description available. This manual page was created by mkman

To convert an RGB into a greyscale image, there are some general practices:

   Y = .2126 * R^gamma + .7152 * G^gamma + .0722 * B^gamma
where gamma = 2.2 typically. This is the Y in XYZ color space. Followed by
   L* = 116 * Y ^ 1/3 - 16
in LAB color space, where L* "... aspires to perceptual uniformity ... closely matches human perception of lightness."

Parameters

The following parameters are recognized in any order if the keyword is also given:
in1=
Input image(s) [???]
in2=
Input image(s) [???]
in3=
Input image(s) []
out=
Output image file [???]
c=
color composition index RGB=(A, B+c*A, B) if only 2 images are used. [0.5]
range1=
Range in image 1 to map. By default the full ranges are used.
range2=
Range in image 2.
range3=
Range in image 3.
