It’s been a long time in coming! I initially wrote this tool many many years ago, then lost the source, but back then it worked only for a very very limited selection of BMP source files. This has bugged me lots, so when I started re-looking at Jaguar development I rewrote it from scratch. However, this time I have used the ImageMagick image processing libraries to enable support for pretty much every image format on the planet. Spent a good few hours last night polishing off some of the rougher edges, and whipped it into an early beta release for people to use. Still a lot to do, if there are any features you would like to see, drop me an email and we might be able to get them added.
The release can be obtained from the Developer > Jaguar Graphics Convertor section of this website.
Enjoy!
