i took a look at all three ring images in this project as well as a few that are 'missing' (in the black areas) in the problematic pano. the masks appear to be pixel perfect in line with the remapped image. when you mention opening up the ring masks above, are you referring to increasing the inside diameter of the ring, thus having a thinner sliver which will be covered by another image?
happy to give some manual mask manipulation a try in the gimp. before i try i'd like to have a better understanding of what you'd like me to try as i'll need to do some research on gimp usage. thanks On Jun 10, 7:24 am, slaterson <[email protected]> wrote: > this certainly does help, i'll try to have a look today. > > once i get the project converted to jpg i'll send a link, also... > > thanks! > > On Jun 9, 2:00 pm, Bart van Andel <[email protected]> wrote: > > > Converting from a TIFF project to JPG is pretty easy.
