I just happened to glance at the mode line in my *Group* buffer:

Isn't there a way to fix this abomination unto man?

  Happy new year!

Worksforme.  Perhaps your Emacs is lacking some image options.

Interesting. I wouldn't think so, it is the Debian unstable package of
GNU Emacs I am using:

  GNU Emacs 24.5.1 (x86_64-pc-linux-gnu, GTK+ Version 3.18.6) of 2015-12-14 on binet, modified by Debian

Hi Adam, I don't get the white background running on Debian unstable
(packages updated today).

Are you using the Gnus that comes with Emacs?

What window/desktop environment do you use?

Does your Emacs startup code change any faces?

cheers,
mike

Hm, curioser and curioser...

No, I am using Gnus from the development repository.

> What window/desktop environment do you use?

I use XMonad as the window manager, without any of the desktop
environments (I use Nemo (fork of Nautilus) for managing files).

> Does your Emacs startup code change any faces?

I have customized a couple of faces (i.e. stored in ~/.emacs.d/init.el
in a call to custom-set-faces); it ends with:

   '(mode-line ((((class color) (min-colors 88)) (:background "grey86" :foreground "black" :box (:line-width -1 :style released-button))))))

But I haven't done anything with faces beyond that.

aybe it's all my own fault?

Could you make a screenshot? Does your look kind of pixelly, like mine,
or is it smoothened?

Mine is pixelated, from etc/images/gnus/gnus-pointer.xpm.

And that file clearly has the background with colour "None". Hm.

I wonder if .svg files can be used in the modeline...

Mine (attached) looks smoother than the image that you posted, but if I
magnify it enough, I do see some pixelation.

Yeah, I think it's the same, it's just the high-dpi scaling stuff that
exaggerates it in my screenshot.

Oh. Hm. Maybe that comes into play here.

Let me try turning it off...

Yes! Now my modeline looks like this:


[-- Attachment #2: gnus-modeline-unscaled.png --]
[-- Type: image/png, Size: 1686 bytes --]

[-- Attachment #3: Type: text/plain, Size: 1580 bytes --]


So the two nice functions Katsumi-san made for me back when I got a
"high-dpi" laptop, are influencing this; they look like this:

  (defadvice create-image (after scale-image-size activate)
    "Scale the image size."
    (condition-case nil
        (let* ((magnitude (frame-parameter nil 'image-dpi-scale-magnitude))
               (image (copy-sequence ad-return-value))
               (size (image-size image t))
               (spec (cdr image)))
          (plist-put spec :width (round (* (car size) magnitude)))
          (plist-put spec :height (round (* (cdr size) magnitude)))
          (plist-put spec :type 'imagemagick)
          (setq ad-return-value image))
      (error nil)))

  (defadvice find-image (after scale-image-size activate)
    "Scale the image size."
    (condition-case nil
        (let* ((magnitude (frame-parameter nil 'image-dpi-scale-magnitude))
               (image (copy-sequence ad-return-value))
               (size (image-size image t))
               (spec (cdr image)))
          (plist-put spec :width (round (* (car size) magnitude)))
          (plist-put spec :height (round (* (cdr size) magnitude)))
          (plist-put spec :type 'imagemagick)
          (setq ad-return-value image))
      (error nil)))

(image-dpi-scame-magnitude is 1.5 on my laptop, for reference.)

So I guess ImageMagick turns the the "None" colour of .xpm's into
white...

Re: *Group* mode line

I think the problem is that images inserted into the modeline get
transparent background rendered as white if they are of :type svg or
:type imagemagick, while if the :type is xpm the transparent background
is "respected".

I turned off my advice's, and I made a gnus-pointer.svg (to get
anti-aliasing), but if I use that, the background of the image in the
modeline is white, even though if I just load the file for display in
Emacs (say with a black background), the background of the image is
transparent.

I guess I should prepare a minimal example...

Hm.  I think that sounds like a bug...  perhaps nobody has played with
SVGs in their modelines much?
