I just got 2 replies from Mark Probst the Mathmap developer

First he pointed me to the doc on how compile it for windows
https://github.com/schani/mathmap/blob/ ... indows-dev

then he told me something surprising about the preview:
the preview SHOULD be resizable , in my experience in Windows is not but if so should be for a error in the windows build

Even more important he pointed me to the part of code regarding the preview, that should help to find how to make resizable also in a windows build (but this seems much beyond my skill) and make trivial change its default size

here the relevant file

Now should be easier recompile mathmap for gimp 2.8, adding for the occasion the many cool filters created after the last , windows build , fixing the preview issue (hopefully making it resizable and pannable as should be..or in the worst case at least bigger ) and make also a 64bit build

Crossing my fingers...

I'm able to resize the preview PC (not to 1:1 though). I just drag the preview window to make it bigger then I grab the actual render Window to make it bigger. Have to do this each time though (window always opens to it's default size).

So it was a problem on my computer ! damn !! i feel as a idiot, also because i never tried to do on linux and i thought was a general problem not a quirk on my PC.

well i hope that at least the Mark tip on the windows build may be of help to update MM for gimp 2.8 and realize a 64bit version

(of course i already have MM working well in gimp 2.8 at 64 bit, still a new build will improve...will improve a lot allowing to use all the RAM and not just 2GB, and will remove the silly warning and the dependency from obsolete .dll )

Crossing my fingers too PC; would definitely appreciate a 64-bit build of MathMap.

Those are the same pages i used to try and compile it.
I had problems getting these compiled first...

well maybe if you wrote on the MM group mark will reply (but not sure how much he may help for Windows)

But may be more rewarding contact whoever maintain that 3 programs you quoted
