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 |

are you just typing
newmap fl73n003.img fl73n003new_1.img -p is this what you typed? what does that mean you made a mistake reading it the first time? did you need to change the code again to make it work or just use different command line instructions? the new one looks right for sure. for some reason I keep getting my .....input file has not been decompressed ERROR and I am wondering if I am missing something simple. |

thanks siravan
I got it to work. My problem was the original file got corrupted somehow so it was screwing up program. From what I understand the final image should be 8466 wide by 2830 pixels height. After running newmap the output image information it generated was 2830 lines x 8466 samples. Your image size of 2116x707 pixel. Where did you get that size? |
