I recently found this map of Europa and GIMP is unable to open it despite my computer being able to open maps up to 64K in size and GIMP supporting JPEG2 files.
https://repository.hou.usra.edu/handle/20.500.11753/1412 Does anyone know how I can open this file? -------------------- "Thats no moon... IT'S A TRAP!"

For the curious who want to see the image without dedicating 30 minutes to downloading and opening the file, here's a small preview of it.

The lighting is different based on which bits of the mosaics are made from which source images and the lighting for those source images. You must do SFS on the source images and then mosaic those outputs. |
