The upgrades available here were primarily produced to overcome issues with running software on the BeagleBoard and other OMAP3 based hardware. The software in question is no longer supported by the original author. In some cases the original application source is still available, and has been recompiled. In other cases compiled versions of more recent support binaries are provided.
Ray Favre's original DrWimp site is now fully maintained once again. The latest versions of the DrWimp library and the various applications (such as Calibre, meDDLe, Labella) are available from there.
A number of applications that process jpeg files make use of the IJG (Independent JPEG Group) software to load or do various transformations. For example, the applications !JCut, !JClean, and !Jigwas make use of the jpegtran binary. The applications themselves are still available (as of 25 Apr 2014) from the Vale RISC OS: Requiescat In Pace site, but the jpegtran binary supplied with them does not run on BeagleBoard based machines such as the ARMini.
The latest version 9c of the IJG software, released in January 2018, has been compiled for use with such applications, and also allows access to newer features such as smart scaling. These versions have been compiled using the Norcroft compiler and SharedCLib, and with the two file command line option, so should be a drop in replacement for the much earlier versions supplied with a range of RISC OS software.

For those who would like to use jpeg routines in their own software, the complete version 9c jpeglib compiled library for RISC OS is available on request.
JCut is an application, originally by 'Dacha', the original is available from the Vale RISC OS: Requiescat In Pace site. JCut makes for easier JPEG cut & paste, cropping, rotating, flipping, and now contrast & colour adjustment - all without the image degradation that would result from decoding the JPEG to process it and then re-JPEGing it. This version has had minor modifications to its !RunImage file to allow it to use the version 9 jpegtran binary.
