Sadly the code for masks in Mask.cpp and Mask.h is totally undocumented. My initial attempt was this: If I have an overlap of two images, I sample one image's boundaries, transform that to the other image's coordinates and use it as a mask for the other image. This would be fine if I could use what's outside of the image as a mask as exclude mask, but the obvious flag in Masks.cpp ( Mask.setInverted() ) doesn't seem to do what I want, the Mask is forever just the inside of the Polygon. So I'm now writing python code for the masks, which is cleaner anyway than my quick-and-dirty approach (it's even fun) - but it' sad that the Mask code isn't a bit more user-friendly. Once I get it to run I'll post again. Kay -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
