Module Update: Panzerkrieg

Module Panzerkrieg Version 2.0: Includes Six Angles graphics, charts, and setup cards with units pre-selected.

I know next to nothing about making modules, but I’m curious - why has this module balooned from the 5.6MB original to 164MB now?

I quickly saw that the module includes a PNG file for the main map (approximately 10.000 x 7.000 pixels) with a size of 140 MB.
I think the size issue is due to that.

I have just submitted a module with a compressed map (a JPG file with essentially the same quality and a size of 12 MB), it should be available soon.

Switching PNGs to JPEGs is typically not advisable, as it introduces artifacts. Better would be to run the PNG through an optimizer like optipng.

I had a look at your map and for this particular map and it’s size in relation to the pieces, I think using JPEG is fine.I also use JPEG for the maps in my modules (never for pieces) and the artifacts are not significant.

A PNG optimizer will have little affect as the colors are dithered right across the map. This is a typical result in scanned output.

Yes, I first tried a PNG optimiser but then opted for JPEG as there were no really visible artefacts and compression was significantly better.
