Major Bug Fixes

The Image Processing Toolbox, Version 4.1, includes the following bug fixes

applycform Fixes

The applycform function includes two bug fixes.

The applycform function did not apply some profiles correctly when the input color was in the XYZ color space. Specifically, profiles containing an 8-bit or 16-bit lookup table containing a non-identity "E" matrix were not processed correctly by applycform. For details about the E matrix, see ICC Specification ICC.1:2001-04, sections 6.5.7 and 6.5.8.
The applycform function now handles correctly Matrix/TRC profiles that contain a single gamma correction factor. Previously, the forward and inverse conversions were reversed.

Compiling Spatial Transformation Functions

Applications that call the imresize, imrotate, imtransform, tformarray, tformfwd, and tforminv functions can now be compiled using the MATLAB Compiler.
