Zoom In and Out Terminal commands ?

[zzeromin]

Hi.

I'm using a Raspberry Pi 3B, 3.x inch TFT LCD with Runeaudio v0.3-beta (23/03/2016).





I want to make Zoom In and Out function using two physical buttons or IR remote in Runeaudio.

I have found some information about keyboard shortcuts and zoom factor, xdotool.

- Keyboard Shortcuts

Zoom in ( aka Ctrl + + )
Zoom out ( aka Ctrl + - )
Normal size ( aka Ctrl + 0 )

- Zoom factor

edit "/root/.config/midori/config"
zoom-level=0.7

* reference: post12370.html?hilit=zoom%20in#p12370

- xdotool

xdotool key Ctrl+plus
xdotool key Ctrl+minus
xdotool key Ctrl+0

* reference: http://xmodulo.com/simulate-key-press-m ... linux.html

But I dont know terminal commands of Zoom in and Out.

Is there anyone who knows how to Zoom In and Out using terminal commands, shell, python, etc?
I would like to develop two physical buttons or IR remote.

Thanks
