The function cvMixChannels is a generalized form of cvSplit and cvMerge and some forms of cvCvtColor. It can be used to change the order of the planes, add/remove alpha channel, extract or insert a single plane or multiple planes etc.

Type: array<System..::..IntPtr>[]()[][]
The array of input arrays.
Type: System..::..Int32
The number of input arrays
Type: array<System..::..IntPtr>[]()[][]
The array of output arrays
Type: System..::..Int32
The number of output arrays
Type: array<System..::..Int32>[]()[][]
The array of pairs of indices of the planes copied. from_to[k*2] is the 0-based index of the input plane, and from_to[k*2+1] is the index of the output plane, where the continuous numbering of the planes over all the input and over all the output arrays is used. When from_to[k*2] is negative, the corresponding output plane is filled with 0's.
Type: System..::..Int32
The number of pairs in from_to, or the number of the planes copied
