Easily generate Minecraft pack icons from within your workspace.
This program was made for a specific use case, so it probably won't be useful in your situation. When executed inside of a Minecraft pack workspace, it scans for an image file matching the regex provided at startup. That image is copied into the first directory found, which is assumed to be the directory of the pack. Then, it is resized and renamed to "pack.png."
The app requires a Java version of 17 or newer.
You should have a workspace with a folder, an image, and the program.
Then, run java -Dautopackicon.iconimagepattern={image regex} -jar {app file name}
in a terminal/command prompt. When the autopackicon.iconimagepattern property
is omitted, the program defaults to (?i)_Back\.bmp as the regex.
Enjoy! 😀
