			%rleCoder Compress data using HDR adaptive run-length encoding.

			% Unlike the description in Graphics Gems II.8 (p.89), code values greater
			% than 128 correspond to repeated runs, while smaller code values are
			% literal dumps. See the following web site for more details:
			% <http://www.andrew.cmu.edu/user/yihuang/radiance_pic/rgbe.html#syntax>.
			% The adaptive RLE used by HDR also does not shift code values by one.
			% There can be only 127 elements in a run.

			scanline = rleCoder_mex(uint8(data), dataLength);

			% Crop the scanline to exclude the unused buffer.
