How to convert modern file formats to Atari 256 colour IMG?

Postby mzry » Sat Jul 29, 2017 11:40 am

Can I just use photoshop? And if my display is 256 colour 1024x768 in THING should I make the image those exact dimensions? Thx

I haven't tried, but netpbm might support this:

pbmtogem
convert PBM into GEM .img file

Thx for the quick response. I had a read of that site and it is a little over my head. I tried to find a binary version but failed.

Which operating system are you on? For Linux and macOS you can just install netpbm through your favorite package manager. For Windows there seems to be a separate distribution here: http://gnuwin32.sourceforge.net/packages/netpbm.htm

They are command line tools. Basically you would run one tool to get the intermediate pbm format, and then another tool to get to img.

I made conversion SW in C - to convert from 256 color, palette based BMP to Falcon and TT screen compatible formats - yes they use not same one.
Unpacked BMP is probably simplest for conversion.
But as I see, you need IMG format . May look here : http://www.atari-forum.com/viewtopic.php?t=18873

I followed that link and tried converting a wallpaper to the degas elite and neo formats, but THING could not display them. Also Xnview doesn't seem to export any atari formats anymore? From what I can see.

Why not using an Atari application? Pixart will help you for sure: http://www.cheshuntcomputerclub.co.uk/i ... t-452/file, just load the file as GIF and save as IMG.

So, what picture/image formats THING supports ?

Just IMG I think. Wow Pixart doesn't like memory protection, crashes a lot :)

"Memory protection" indicates that you're using MiNT, so why use Thing! backgrounds? Both MyAES and XaAES are capable of displaying truecolour backgrounds, no need to limit yourself to 2567-colour IMGs.

Ok thx for the advice I'll do a quick search on Xaaes backgrounds and what are the best file formats.
Edit, found the guide I'll add it here for others to reference if they need it:
1. Run zView.
2. Load your wall paper on to it, then make it full-screen by pressing F10.
3. Capture the screen to use as wallpaper by pressing CTRL-ALT-colon (note: colon is SHIFT plus : ).
So it is 4 keys pressed together.
4. Close zView and you will see the wallpaper.

I made a BMP2XIMG tool for making falcon 256 color background, it's a tool for windows or that can also run on the falcon itself:

(at the bottom of the page)
The GEM palette is included to make your wallpaper correct and not screwing up the GEM base color
