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.
