How do I zoom 200% in feh without having to use fullscreen?
Solution 1:
feh
basics
In Ubuntu I find the following description in man feh
--zoom percent | max | fill
Zoom images by percent when in full screen mode or when window
geometry is fixed. When combined with --auto-zoom, zooming will
be limited to the specified percent. Specifying max is like set‐
ting --auto-zoom, using fill makes feh zoom the image like the
--bg-fill mode.
Zoom works for me not only in full screen but also with fixed geometry according to the following example,
feh --zoom 200 --geometry 1500x500 zenity-info-message.png
Shellscript that makes feh --zoom
nicer
The following shellscript fixes the geometry parameter automatically for each,
#!/bin/bash
function usage {
echo "Help for ${0##*/} by Nio Wiklund <nio.wiklund at gmail.com>
Usage:
${0##*/} [--zoom <percent> [--position <+X+Y>]] <picture-1> [picture-2] [...]
Examples:
feh-zoom --zoom 200 picture.png
feh-zoom --zoom 50 --position +400+200 g*.jpg
--zoom <percent>
Zoom images by percent. Will create a correct window size automatically.
. this option is modified in this shellscript compared to feh.
--position <+X+Y>
Position of the picture-window's top left corner
(offset X pixels and Y pixels from the screen's top left cormer)
. this is an option only for this shellscript, but not for feh.
<picture-1> [picture-2] [...]
. Specify at least one picture. Wild-card works, e.g. *.png
. Switch to the next picture with 'q' (while you do it with -> in feh).
Quit with 'qq' (press 'q' twice within one second).
. The standard options for feh (for example --randomize) will fail
because feh is called for one picture eash time in a for-loop, and
no more options are passed.
If the first option is not --zoom, this shellscript passes control to feh
directly, so that all the standard options for feh will work.

Thank you, sir, for your help!
I see I should read the manual more carefully next time, but anyway am I positive that I have to use the following command to zoom my picture twice?
feh --zoom 200 --geometry $(feh -l pictorius.png | awk '(NR==2) {print(($3*2)"x"($4*2));}') pictorius.png
Honestly, it sounds like a bad joke. Or is there a simpler way?
