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. In this version two bugs have been fixed:
(1) Fixed a bug which caused the output image to be completely black when converting MEx HRSC DTM files. (2) IMG2PNG now correctly converts input files containing processed LROC images created from the original, raw data. An example is mosaics of LROC NAC images. Earlier versions of IMG2PNG confused these images with the raw images, resulting in strange (and incorrect) output images. As usual, IMG2PNG is available here. The LRO bug fix addresses the issue mentioned above by sjones on August 12, 2014 (this has taken far too long for me to fix, especially since this turned out to be a trivial issue). A cumindex.tab file is now not needed to convert the file mentioned there since that file is a mosaic of LROC images and not a raw LROC image (where a cumindex.tab file is needed). The LRO Diviner Lunar Radiometer Reduced Data file also mentioned by sjones actually is (and was) correctly converted. It's just that the output image is very dark but not completely black - the pixel values range from 0 to ~600 which is very dark in a 16 bit image where the maximum value is 65535. |
