I have an image in PNG format with some transparency - 25mb 70000x40000
When I use this library to transform it to JPG file with overlap 2, everything is amazing.
But my goal is to keep the transparency, so I use PNG suffix with same overlap, but with the PNG there are micro lines when displaying it with openseadragon. I assume there is something wrong here as JPG works fine.

- has micro lines that shouldn't be thereCould you please help me how to fix it?
Here you can see the micro lines:
