IMG2PNG, PDS/FITS to PNG conversion Options

[Bjorn Jonsson]

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.

Original image from Cassini's ISS can be 8-bit, but if you use img2png with calibration, than output is 16 bit png. Without calibration procedure is output 8 bit png when original is 8 bit image, or 16 bit png, when original is 12 bit image.

BTW, I tried new user-specified calibration procedure on old Voyager images.
It looks, that img2png accept well my calibration files, but new version can't read and convert imq files (old version has no problems with them).

That's weird, converting imq files works perfectly on my end, both with and without a calibration file. Are you using the most recent beta version? If yes (or if the most recent version does not work either) please post the error messages (if any) that appear plus a screenshot similar the the one posted by S_Walker at the top of this page (or, using copy-paste, the text from the command prompt window).
