I've done a lot of testing to try and figure out the best way to modify the alpha masks that are fed to enblend. My current preferred solution would be to implement the proposal here: http://wiki.panotools.org/SoC_2009_idea#Simple_mask_editing i.e. put a mask editor in the hugin Crop tab, save the masks as vector/polygons in the .pto project file and apply the mask at the nona rendering stage (i.e. this wouldn't involve modifying enblend). Though one of my test tools is enblend-mask: http://search.cpan.org/dist/Panotools-Script/bin/enblend-mask This is a wrapper that allows you to have an external bitmap mask for any enblend input file, the idea is that you manually edit masks in these external easily compressed files and the two masks get merged before blending. This is useful because you never want to keep the enblend input files afterwards, so editing them manually is bad. I think it would be trivial to add this as an option to enblend and it would also be useful. The other test tool is tiff2svg/enblend-svg: http://search.cpan.org/dist/Panotools-Script/bin/enblend-svg This is another wrapper, it uses a multilayer SVG file to specify enblend input, this is useful because SVG supports polygon masks. This is currently the only 'nice' visual way to easily do masking, but it doesn't scale because none of the SVG tools deal with cropped TIFF or 16bit images properly. Hence my preference for doing masking in hugin eventually. -- Bruno --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
