Readme for Hugo JPEG translator =============================== This tool is most useful for Acorn computers (or any others for which Progressive JPEGs are less easy than non-progressive). It takes a Hugo resource file and uses the IJGs code to convert any jpegs therein into non-progressive form. It also attempts to compress jpegs better (with no loss of quality)[1]. A scarce few files are provided here, just README, a makefile, and a c code file. The other required source files should be obtained from ftp://ftp.uu.net/graphics/jpeg/jpegsrc.v6b.tar.gz and then arranged into the appropriate directories. The Makefile[2] should then build the required htran binary (also provided in the bin directory). Ignore any switches you might expect to work, just use as htran -outfile [3] This should allow games provided with progressive jpegs in Hugo resource files to be played on Acorns. A final note - I hacked this program together very quickly, so please don't read the source code... and if you have to, close your eyes whilst doing so! [1] eg. GB's main resource file goes down just over 12% [2] I use Acorn's Make Utility. If you don't, your milage may vary... [3] I wouldn't advise making the filenames the same!
