Lossless JPEG transformations made easy with TranJPEG
You spin me right round, baby, right round, like a record JPEG baby, right round round round. Chris Johnson, well known for a number of applications, in particular the likes of Snapper and SyncDiscs, both of which began life with David Pilling and later taken over by Chris, recently announced version 1.00 of TranJPEG (mirror), soon followed by updates to version 1.10 and 1.20, which presents a RISC OS front-end for the Independent JPEG Group command-line utility “jpegtran”, giving the user a friendly and easy way to make use of…

There are a number of applications available for RISC OS that carry out various transformations on JPEG files, such as JCut, JClean and Jigwas. These make use of the IJG (Independent JPEG Group) software to apply the transformations but, unfortunately, the “jpegtran” module supplied with these applications will not run on the BeagleBoard. Some months ago, Chris Johnson reported that he now had a working jpegtran module, but had needed to modify the BASIC programs that called it. He has now recompiled the IJG software (version 6b, as originally used…

Posting to the ARMini support mailing list, user Ross McGuiness asked a little over a week ago about the application JCut, and whether there was any chance of it being made ARMini (and Beagleboard) compatible. The software is part of a small suite of programs written some years ago by J. David Barrow for manipulating JPEG files without re-sampling them, and thus without causing any reduction in the image quality that normal editing can cause. The software does this by way of the Independant JPEG Group utility ‘jpegtran’, providing a…
