Re: DocView resolution for PDF on WQHD

[Van L]

Thanks,

> (setq doc-view-resolution 192)

I was able to find 'resolution' in M-x customize.

For WQHD I calculated

(/ (sqrt
    (+ (* 2560 2560)
       (* 1440 1440)
       ))
   25) ; which is approx. 118 PPI¹

and the out of the box setting is 100.

Setting 'Doc View Resolution' to 192 and reloading the PDF doesn’t improve the 
font rendering.

See² for side-by-side comparison. 

On the right side is the inferior Emacs’s PDF view.
