There has, understandably, come up some questions how the heck to convert a photo to
Atari ST medium resolution and the Degas Elite PI2 format.
Here are two ways, one is very easy, the other a little more techy.
Method 1 - Easy web browser based
Browser based Javascript tool made by Percy of Light.
- Convert your image to 640*400 truecolour with your favourite graphics tool
- Scale the image to 640*200 (it will have the wrong aspect ratio, but the ST will double the lines!)
- Save as 24-bit PNG
- Start Animas IMENHANCE
- Set it up like:
- Colourspace: Atari ST (512 colour palette)
- Screen size: 640x200
- Max. colours: 4
- Dither colour bleed reduction: Experiment yourself
- Quantisation colour preservation: Experiment yourself
- Luminance delta (flickering): Experiment yourself
- Once setup, select file and see the result.
- The last two images are valid (Quantised Atari ST Degas image and Quantised and dithered Atari ST Degas image)
- Save the one you like best and submit your entry!
Good luck!
Method 2 - Expert Java commandline based
Commandline Java tool made by Troed of Sync.
- Convert your image to 640*400 truecolour with your favourite graphics tool
- Scale the image to 640*200 (it will have the wrong aspect ratio, but the ST will double the lines!)
- Save as 24-bit PNG
- Download the tool from: https://github.com/troed/PNGconv
- Convert your saved PNG image with the following commandline
java -jar PNGconv.jar shphoto.png shphoto.pi2 medium -512 -header
- Submit your entry!
