Re: ["gtk-i18n-list"] Font Rendering backends

[Michael Gummelt <mgummelt1 gmail com>]

Here are the two images side by side: http://imgur.com/zqKoB6k,POLlkVl#0

The first is graphical emacs, while the second is rendered by the terminal (terminator).  They're slightly, yet definitively different.

I'm not looking for all the possible reasons, but rather an overview of the font rendering system, and how Pango/xft/fontconfig/X11 all interact.

Thanks,

Michael

Hi,

There might be so many possibilities of the reason why they
are different, so I recommend to post the screenshot how
they are rendered differently. However, I'm unfamiliar with
the font backend in Emacs...
