This is an extension for Tk400.* or Tk402.* which supplies JPEG format loader for Photo image type. The sub-directory jpeg is release 5 of the The Independent JPEG Group's (IJG) free JPEG software with only the addition of a (dubious) Makefile.PL. This package is not distributed with perl/Tk due to different portability and licencing issues see jpeg/README for details of IJG's license. It is likely it will not work as-is with tk8.0 merge (Tk80?.*) when that happens due to changes in tk internals. It looks as though it would be fairly easy to add -data loading and writing, although the value of saving dithered image as JPEG is uncertain. The build process does not follow a proper MakeMaker mechanism yet. In particular Makefile.PL in jpeg directory just invokes IJG's GNU-ish 'configure' script. Thus some hand intervention may be required. That said : perl Makefile.PL make make test Should build it. Nick Ing-Simmons
