math symbols rendering issue on Bigme Inknote color+

serige · 03-29-2024, 07:17 PM

I have been using koreader in my sony eink reader for a few years now and it works really well. I recently moved to the Bigme Inknote Color+ for the colors experience. However, I can never get koreader to render math symbols correctly under my new device (see attached sample page). I really hope I can find the solution here.

You mean the fact that small fonts are grainy?

I don’t think this is KOReader’s fault. Color devices usually have grayscale layer at 300 dpi, but their color layer is 150 dpi. You might the effect of this degradation

Oh, I might be wrong, sorry. This is a screenshot, right? Can you attach a page from the file so we can try?

My bad, looks like this is the pdf's problem. I was using the default reader from the device and the font was fine, so I was thinking that's KOReader’s fault, but I just found out that the default reader was reading a different pdf without this font issue. I am just stupid
