kdu_region_decompressor::process

This function is equivalent to invoking the first form of the overloaded process function, with four 8-bit channel buffers.

• The 1st channel buffer (nominally RED) corresponds to the 2nd most significant byte of each integer in the buffer.
• The 2nd channel buffer (nominally GREEN) corresponds to the 2nd least significant byte of each integer in the buffer.
• The 3rd channel buffer (nominally BLUE) corresponds to the least significant byte of each integer in the buffer.
• The 4th channel buffer (nominally ALPHA) corresponds to the most significant byte of each integer in the buffer.

If the source has only one colour channel, the second and third channel buffers are copied from the first channel buffer (same as the expand_monochrome feature found in other forms of the process function).

If there is no alpha information, the fourth channel buffer (most significant byte of each integer) is set to 0xFF.

If the number of channels or colour channels is incompatible with the representation described above, an error will be generated through kdu_error.

Apart from convenience, one reason for providing this function in addition to the other, more general forms of the process function, is that it is readily mapped to alternate language bindings, such as Java.
