How do I zoom 200% in feh without having to use fullscreen?

This works:

feh --zoom 200 --full-screen picturius.png

I need the same without full-screen:

feh --zoom 200 picturius.png # this does not work

Have you an idea where I am wrong?

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.

Make the shellscript feh-zoom executable and put it in directory in PATH. There is a help text,

$ feh-zoom -h

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?
