Hi there! Thank you so much for this tool - it saved me a ton of work :)

I found myself needing to run this tool across an entire game project's worth of art several times, to fix some palette inconsistencies I made early on. As far as I can tell this functionality doesn't exist yet within the GUI, but I wrote a Windows .bat file that more or less does exactly that, so thank you for making the command-line tool available! I'm attaching the script contents here in case this helps anyone else.

To use:

• set the "ppt" variable to the location of PixelPaletteTool.exe
• set the "swapfile" variable to the full path & filename of the swap file you're using
  • this is generated by using the GUI to set up your color swaps and then using the "Save" button near the word "View"
• set the location of your input directory
• set the location of your output directory
• save the following script into a Windows .bat file and run

Running this script will a palette swap every .png file in the input directory and save the result in the output directory, following the same folder structure.
