The fat json that your script downloads can be inspected for that. The 'text' attribute contains the base64 encoded data that represents the binary. That can be decoded. Thus is it possible to go through a fat json tiddlers collection and extract all the images to separate file.
I've made a quick python (works for both 2 and 3) script that will do this for images: https://gist.github.com/cdent/1254a9c98d8ba316e6c0223f9dd03925 If you run it in the directory where the fat json files are as `python extractbin.py *.json` all the image tiddlers will be dumped into a directory named 'binaries'. I hope this is enough to keep people some ideas on how to process the data. There are also ways to search tiddlyspace for tiddlers of particular types, but since the fat json already includes the data locally processing that seems easier. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
