It is there, but I am using a screen blending mode on the stroke, so it disappears. I have an Idea that may bring it back and make it pop a little.
Thanks for the feedback!
Well. Apparently even though I moved the convert.exe to the batch folder, ImageMagick still needs to be installed on the system. I will update the readme. I should probably update the batch scripts to use the default path in case someone already has IM installed and it is incompatible
That is a problem with the core you are using, try a different core. If you must, I think you could batch flip everything using xnconvert form the xnview software.
edit: scripts, readme, and repo have been updated.
