Re: Apple II graphics conversion

Hi Brendan,

Yes, I just saw your post on the comp.sys.apple2.programmers when you
added the code to AGS.

I just tried downloading and running AGS 3, and it complained about
the rxtx library not being where it should be (I'm running it on a
Windows 2000 machine and just installed jdk1.6.0_14) and so I
downloaded the rxtx library and that talked about needing to be
compiled and I wasn't sure how to do that.

So I've hit the ceiling of my abilities unfortunately because AGS 3
sounds like great software - but I think you are really limiting your
audience if they need to compile/tweak and do other things to get it
to work.

I appreciate that the graphics code is available but I wouldn't begin
to know where to start since I don't know how to do "hello world" in
java...

Is there a way to make the code above into a standalone applet that
you can double click on – and have the ability to choose an image –
which then it saves to .dsk that could then be read/copied by an
emulator / Ciderpress?

Or, if it makes it easier, it just converts whatever file is named
image.jpg that is in the same folder as the applet?

Regarding bit collision, the only thing I’ve seen along those lines is
Lazilong’s work – his Apple ][ HGR to modern image format application
& Photoshop plug-in (Mac only).

Some samples here: http://www.lazilong.com/apple_II/a2pix/images/scrnshot/index.html

Excellent DHGR demo image showing differences:

I realize that this is going the opposite way – from existing HGR to
modern format – but I thought it might be of use.
