	array<int>^ fromTo
)
Parameters
src (array< IntPtr >[]()[])
The array of input arrays.
dst (array< IntPtr >[]()[])
The array of output arrays
fromTo (array< 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.
