Description

Attached file is displayed blue, but should be mixed. This is an axial shading with a type 3 (stitching) function made of type 1 functions. I did some research but have given up for now. The colorTable in AxialShadingContext.java has all sort of values between 80000 and 40000. However these get reduced to values between 1 and 2 when in getRaster(), but should be between 0 and 1 to appear.
