DiddleBug Extractor 2.1
Drawing pictures on your Palm
I use an excellent free Open Source program called DiddleBug on my Palm Treo 700p for doing small black and white drawings. The latest version of DiddleBug creates 320×320 pixel size drawings. These are referred to on their site as “high-res” pictures instead of the 160×160 pixel size drawings that older versions of the software created.
Getting DiddleBug pictures off your Palm
I used to use a nice converter on my Windows laptop called WindleBug but wanted to be able to just use my Mac laptop by itself instead.
The DiddleBug FAQ mentions using a Perl script called Didcon on Windows, Linux and OS X which hadn’t been updated yet to extract the new 320×320 pixel sized images. When I ran the Didcon script for the first time, it saved out a 160×160 graphic that had weird lines running throughout it, due to the fact that it wasn’t reading out the data for a 320×320 pixel sized graphic.
After hacking at it for a little while, including researching how to correctly indicate the pixel size of an image in a Windows bitmap in the header of the file, I managed to get a working script that correctly outputs a 320×320 .bmp file.
This is the modified script, and I’m also including a second script that you can double-click in the Finder to run the extraction process.
