Problems with mosaic

[dnault42]

Not that I know of.  I've tossed around an idea of how to do this in script form.  You could create previews around the offending stars and then have the script set all the values in the bounding boxes of the previews to zero.  However, I agree, what would make this very easy is exactly what you described, a reverse dynamic crop and to do that I think you really need to develop a module.  While I know C reasonably well, I'm not really a developer and wouldn't know how to even compile something like a PCL module that popped up a 'Hello World' window.

You may not be a developer but you tossed up a few words that I have no clue what they mean.

You might want to look at a module(not a script) that Carlos Milovic created called Seed. http://www.astrophoto.cl/Research.html Seed creates a mask. The rectangular section can be used for exactly what you want. Define your upper left x and then the lower right using the mouse and the Set coordinates box. Change grow pattern global parameter to 0 and execute. You then use the Binarize to make a clean black/white mask. Apply the mask and invert. Then use pixelmath and 0 the masked area. That's a lot of steps. I made a set of process icons(Seeding.zip) just for the last parts, simple drag a drops.
