DocView face - change of colors

DocView face - change of colors

[Colin Baxter]

I notice in emacs-30.50.0, probably as a result commit 26740f30469, that
my pdf files display as white text on a black background. I have
reverted back to my desired setting of black text on white by putting
the variable `doc-view-mupdf-use-svg' to nil, so it's not a problem for
me right now. However, I worry if by setting doc-view-mupdf-use-svg to
its non-default value I am storing up problems in the future.

My question is therefore is there any other way of getting my desired
effect other than setting doc-view-mupdf-use-svg to nil?

The doc-view-pdf->png-converter-function is set to mupdf if that is
significant, although I do also have ghostscript (v 9.26) installed.

Thank You.

Colin Baxter.

Hi Colin,

I think you should keep `doc-view-mupdf-use-svg' to t by default.  The
commit 26740f30469 have introduced a new face `doc-view-svg-face' which
you could use to customize how your DocView documents are displayed.

By default, this new face inherits from the default face.  So I guess
that you are using a "white on black" theme and that is why your DocView
are displayed with this theme too.  You could, for instance, customize
`doc-view-svg-face' like this:

--8<---------------cut here---------------start------------->8---
(custom-set-faces
 '(doc-view-svg-face ((t (:background "white" :foreground "black")))))
--8<---------------cut here---------------end--------------->8---

As DocView uses the SVG rendering, only foreground and background colors
are relevant for this face obviously.

Great! Thank you so much for this. It works very well.
