I am struggling to make a VASSAL module. I had some help making an early version where the unit piece images were at 300 DPI, which made them too big. I rescaled the piece images to 150 DPI and was wondering if there is a simple way to mass replace the images ?
The vmod is just a zip. Change the vmod to zip and unzip it. You’ll find an image folder. Overwrite your old graphic files with your new ones. Re-zip everything and change it back to vmod.
VASSAL allows zooming in arbitrary amounts, so higher DPI images can be extremely useful.
Edit: Also, you’re very out-of-date if you still think displays are limited to 72 dpi. My 27-inch 1440p monitor has a PPI of about 108, for example, and phone displays can get into the many hundreds (see this page, for more examples).
Oh, OK, yes it is a long time since I was learning about making web pages and every book I read said that. That makes getting the file size smaller more difficult!
