DESCRIPTION
Each of the functions provides support to reversible wavelet transformation. It is for reversible color space conversion.
PARAMETERS
Each of the functions takes the following arguments:
y Pointer to destination Y component.
u Pointer to destination U component.
v Pointer to destination V component.
r Pointer to source R component.
g Pointer to source G component.
b Pointer to source B component.
n Length of data.
depth Number of bit planes required to store the original R, G, and B components.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
