Hi again Jason,

As i was saying before, als_dj.exe is my own jpeg decompressor, while
GdiPlus is a .dll written by Microsoft.  als_dj.exe is written in the
C language and compiled using a Microsoft compiler.  GdiPlus is
available as a free download from Microsoft for systems that dont
already have it (Win95+ required).
Now that you mention it, i've never written a help file for als_dj.exe
but you can get plenty of ideas by opening a command box and navigate
to the directory where als_dj.exe is located and type at the prompt:
  als_dj.exe
or
  als_dj.exe/?
to see plenty of command line options.

I dont think this will be much help, but if you're interested in finding
out more about the jpeg decompression process you can download my
"JPG Reader" which shows the basic decompression scheme.  Every bit of
the process is done in Euphoria, so you can single step through every
part of it.  Do a search or download here:

I dont think that's what you want, but just in case you're interested
in the file decompression itself that's the best example i know of
on the web :)  especially if you want to design your own decompressor.

Note that scaling the picture size isnt as easy with als_dj as it
is with GdiPlus, but als_dj will decompress some files that are 
corrupt to some degree whereas GdiPlus will return an error.
GdiPlus still being the more versatile however.


Take care,
Al

And, good luck with your Euphoria programming!
