Default software to create "robinson projection" map

anyone know a way to convert existing maps eg the MOLA rectangularised map of mars into a Robinson Projection ?

Preferably using something free rather than for example buying the newest version of photoshop/illustrator so i can learn how to install plug-ins for it

Robinson projection ..... sorry I thought it was well known.

an exaggerated circle the poles also stretched so you have the whole world on one shape:



instead of what we grew up with:


or the traveller isohedral world maps

You can probably just buy a Mars map in that layout from the '90s, if any map companies were still using that standard.

I've made Mars maps for Traveller using IS Map Form 8 from Traveller 5. But they are all terraformed though.

NASA provides numerous publicly available programs (with source code), such as http://www.giss.nasa.gov/tools/gprojector/ and http://seadas.gsfc.nasa.gov/ that are multi-platform and will do map projections.

I'll do another one in relief. I'm hoping I can hide the seams, if there are any.

ADDED:
This one is a little better: http://www.shonner.com/shawndriscoll...nson_mars2.jpg

from what i saw in the discussion on one of nasa's sub sites about making that NGS map I linked is actually your color map merged into a shaded relief map made by MOLA data

BTW there is a command to change the lat + long lines. I found 90 to be best when rotating and then 0 before saving
