profileQA

Assess quality of an ICC profile.

Function performs two tests on an ICC profile which are designed to assess aspects of its quality. The first test does a round trip through the B2Ax & A2Bx transforms of a clut profile and reports statistics on the differences. The second test exhaustively samples the input Lab space of a B2Ax tag and selects those colors which yield inkings that are within an epsilon of a target inking. 3-D plots are generated for each test.
