Hoping someone can help.
I am trying to uncompress the FMAP .img files which are part of magellans images of venus so I can use a converter program to convert them from sinusodal to cylindrical mapping. Things I do know is that I can just rename .img to .raw and open in photosho however the converter program newmap.exe which is an old dos program that is provided with the FMAP images requires I think the uncompressed .img files in order to convert sinusodal to cylindrical. I know the .raw didnt work. And I get error saying my .img files are compressed so it wont work. I know .img files are not cd or dvd image file or so I think becuase I could not open them in MagicISO If they were CD images I would think MagicISO would work but I may be wrong though. Anyone familiar with what I am trying to do. Any image processing guys out their do this with the magellan FMAPS? I figure the experts would be here. thanks |

This is the file I got:
I'm not sure about the vertical line in the middle. Is this expected in reprojection? The source code is newmap.c.zip ( 10.66K ) Number of downloads: 796 . It still needs to be run in command prompt. Note that I could not reproduce the error. |

I have to think on this now. Its not what I expected. I didnt expect a line in center but we may be getting into territory of blind leading the blind since i am still learing this program.
Can you tell me exactly what you typed at the dos prompt while using newmap to get this image? |
