settings in policy.xml on Debian testing

Hi! I just stumbled across, what I believe to be either a bug or some unconstructive preset found in /etc/ImageMagick-6/policy.xml: <policymap> <policy domain="resource" name="memory" value="256MiB"/> <policy domain="resource" name="map" value="512MiB"/> <policy domain="resource" name="width" value=...

Re: change projection style on DePolar distortion?

Ah, I see, then it seems to boil down to the ArcSin function in the generation of the map.

BTW, why gets that first image loaded? To get the correct size for the diplacement map?

Re: change projection style on DePolar distortion?

I don't know what is mathematically wrong with your result. From the looks of it, the mathematical function is about right, but much too pronounced. So I thought, maybe, as a first guess, just get the strength/amplitude of that curve to 50%, to see if we're getting closer. I'm just not quite sure, ...

Re: change projection style on DePolar distortion?

This actually worked into the right direction! Still it needs adjustment, but getting closer anyway! https://musicchris.de/public_pics/FGearthview/world_icemap_2.jpg I assume, this has sth to do with the Displacement Map? If I reduce the values from convert -monitor tmp/arctis_16k_cropped.mpc -spars...

Re: change projection style on DePolar distortion?

Thanks for the directions! This looks very promising, though I need to learn some more of the way you "call" IM. I'll read up on that... Thanks! Edit: I think I figured it out - you use Windows .bat format. So All the %foo% is just a variable, sometimes declared via set foo. %IM% seems to be the pat...

Re: change projection style on DePolar distortion?

BTW, is there some operator I could use on the depolared ice map overlay? Like some distortion - stretch it on the upper half and compress it on the lower half? Any ideas?

Re: change projection style on DePolar distortion?

Ok, thanks. I'll try to find out, what kind of projections I'm dealing with, and see, how I can apply that to the result, rather than to the DePolar. Since the polar map clearly is no projection of a sphere (the 15° lines should become closer to the edge).

Cheers

Thank you for IM!

Hey there! I rarely used IM, most things I can do with GIMP, resizing an image and such. But lately I had to work on huge world maps and sattelite images. sizes range from 51000x27000px to about 24000x24000. Try loading this into GIMP! :lol: Additionally I needed a way to automate this. Now I'm very...
