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. |

A new version of IMG2PNG is now available. This is a very important upgrade if you have been using IMG2PNG to convert files in FITS format. There was a bug in the old version that caused the resulting PNGs to be mirror-flipped up-down but this has now been fixed. Relatively few of the planetary imaging data sets are in FITS format but e.g. the NEAR and New Horizons images are (luckily this bug was discovered before the Pluto flyby!). Conversion from PDS (.IMG) files worked correctly.
There is also one minor new feature in this new version: If you generate thumbnail images in addtition to full size images it is now possible to specify the thumbnail size. This is done by adding an optional number to the -t or -thumbn command line parameter. For example, "-t10" or "-thumbn10" generates thumbnails 1/10 the size of the original images. If the number is omitted a value of 4 is used. Some minor bugs have also been fixed. In particular, converting Clementine images should now work in all cases. As usual, IMG2PNG is available here. If you already have IMG2PNG and only want to download what has changed you can download this small ZIP file which only includes what has changed. |
