[josm-dev] Image extraction from TMS cache

[Holger Mappt]

Hi,

I re-package josm-latest.jar into my cachextractor.jar to have a self 
contained archive. I missed to copy data/preferences.xsd, which killed 
my JOSM preferences. Now I copy directory data in addition to **/*.java 
and the cache read works.

What do I need to do to shut down JOSM if it was started with the 
functions in JOSMFixture.init() (no GUI mode)? Looks like there is a 
background process. I call System.exit(0), but I would like to stop all 
running processes first.

The other thing that caused me some headache was the export disk file 
format. The old cache that wrote tile files to disk wrote *.png files. I 
tried different PNG writers, but my files were always about 8 times 
bigger. It took me some time to figure out that even JPEG files were 
written with the .png file name extension. Now I save the tiles as JPEG 
and everything is fine. Does the current cache have information about 
the original tile file (format, data)?

Regards,
Holger
