Tachiyomi: Image Sharpener

[basilg3]

Though this feature is not absolutely necessary, I believe that many manga scans could benefit greatly from a feature that would simply sharpen the display of a given manga chapter. Perhaps this feature could be acessed via the settings gear at the top right of the page, and be located under the "Image Decoder" option. I would imagine that a feature like this would come equipped with a "slider" that would determine the intensity of the sharpening effect, similar to how the Custom Color Filters have intensity "sliders" of their own. Of course, I understand if this feature is not feasible or possible, but it's something that I hope can be looked into. Thank you.

, reading blurry japanese can be pretty hard when you are a beginner ><.
I don’t know if it’s possible performance-wise, but you could take inspiration from how it’s done in imagemagick

I think Lanczos3 support or something like that would suffice, too.

Would prefer not to bloat the app with extra image processing stuff. I'd recommend finding a better source.
