I decided to create a special thread for this topic. Previously information on IMG2PNG was scattered across various threads here.
I new version of IMG2PNG is now available. For those that don't know, this is a command line uitility that can convert various PDS formatted files to PNGs (8 or 16 bits per pixel depending on the input files). This utility should work for lots of different PDS files, e.g. MER, Pathfinder, Voyager, Galileo, Cassini, Stardust, various Mars orbiters, Mariner 9/10 (!), Viking Orbiter, Viking Lander, Magellan, Clementine, Messenger, New Horizons etc. The major new feature in the new version is the ability to convert FITS files. IMG2PNG can be downloaded by visiting http://www.mmedia.is/bjj/utils/img2png Any information on possible bugs welcome. |

I now have an alpha version of a new IMG2PNG where the majority of it has been rewritten from scratch as indicated in my previous message. As I hoped it's far easier to maintain and modify than the old version.
This new version correctly converts the Smart-1 data mentioned above by Doug and it also correctly converts the Voyager images that Ian mentioned above (the old version didn't). Also it correctly flips the LRO NAC images if you have the new version of the index.tab (or cumindex.tab) files. Actually the new version is far more flexible than the old one when dealing with various 'variants' of PDS formatted files so it should already be more robust than the old version when dealing with most files containing single band 8 or 16 bit data. Not all features in the old IMG2PNG have been implemented in the new alpha version. There is no calibration stuff yet (this impacts the conversion of MER and Cassini data) and files containing floating point data cannot be converted. If anyone is interested in trying out the new alpha version (and maybe discovering some bugs ) send me a message. It should mainly be interesting if anyone is interested in Smart-1, LRO/NAC and maybe Voyager but others are generally better off using the old version unless it does something strange. In a few days I should have a version ready for testing. Finally, if there is anything you have ever wanted IMG2PNG to do that it doesn't currently do this is the time to mention it. Needless to say I cannot promise to implement everything everyone suggests but I'm open to good ideas. |
