Running demo, text-scroller etc, on a cube

[AnAxNu]

I built a LED matrix cube using 6 64x64 LED panels, a Raspberry Pi 3B and a ElectroDragon "RGB LED Matrix Panel Drive Board".
I have connected 2 LED panels in each chain and then use all 3 chains.

I created a 128x192 image that has 6 64 pixel squares with numbers, so I can see what goes where in the cube.
The image looks like this:
[1][2]
[3][4]
[5][6]

I show the image on the cube using this command:
sudo ./led-image-viewer 128x192.jpg --led-rows=64 --led-cols=64 --led-slowdown-gpio=4 --led-show-refresh --led-chain=2 --led-parallel=3 --led-brightness=20

This works perfectly, each side of the cube show a number.

My problem now is that I do not know how to proceed using other cool code.
A simple example would be if I run the text-scroller only side 1 and 2 of the cube show the text scrolling.
This is expected since the text-scroller does not see my display as a cube but a 128x192 display and side 1 and 2 together is the full width is the display.
But how would I go about getting the text to scroll around my cubes 4 sides?
In one configuration this would mean that the text would scroll though panel 1,2,3 & 4.
(because of short cables my cube sides are currently 1,2,3 & 6 - and bottom is 4 and top is 5)

Another example would be how to get the demo to work with my cube, since this also get split up on different sides:
sudo examples-api-use/demo -D0 --led-rows=64 --led-cols=64 --led-slowdown-gpio=4 --led-show-refresh --led-chain=2 --led-parallel=3 --led-brightness=20

In the longer run would I like to get the AdaFruit cube software to work, but since they use a single channel hat maybe that is difficult.

I started to do some coding to get the Adafruit cube to work using the ElectroDragon board (and also a BBC Micro:Bit accelerometer instead of the LIS3DH) and then came back to trying to get the text-scroller and led-image-viewer to work with the Adafruit cube configuration (placement and orientation of the panels).

There is ongoing discussion about a mapper Here, that would probably do what is needed but I wrote my own while messing with the cube.

Using my mapper I get the text-scroller and led-image-viewer to work on a cube, put together according to the Adafruit guide, using:

sudo ./text-scroller --led-rows=64 --led-cols=64 --led-slowdown-gpio=4 --led-show-refresh --led-chain=2 --led-parallel=3 --led-pixel-mapper="Rotate-panel:0|270,5|90;Reorder:4|1,3|0,2|3,1|5,0|1;Row-mapper:H" --led-brightness=40 -f ../fonts/9x18.bdf "... Hello ..." -y 20 -C 0,200,0
sudo ./text-scroller --led-rows=64 --led-cols=64 --led-slowdown-gpio=4 --led-show-refresh --led-chain=2 --led-parallel=3 --led-pixel-mapper="Rotate-panel:1|270,2|0,3|90,4|0;Row-mapper:V" --led-brightness=40 -f ../fonts/9x18.bdf "... Hello ..." -y 20 -C 0,200,0

sudo ./led-image-viewer --led-rows=64 --led-cols=64 --led-slowdown-gpio=4 --led-show-refresh --led-chain=2 --led-parallel=3 --led-pixel-mapper="Rotate-panel:1|270,2|0,3|90,4|0;Row-mapper:V" --led-brightness=40 ./256x64.png
sudo ./led-image-viewer --led-rows=64 --led-cols=64 --led-slowdown-gpio=4 --led-show-refresh --led-chain=2 --led-parallel=3 --led-pixel-mapper="Rotate-panel:0|270,5|90;Reorder:4|1,3|0,2|3,1|5,0|1;Row-mapper:H" --led-brightness=40 ./256x64.png

The Reorder mapper I wrote is ok to use to swap a panel or two but not very intuitive to use when reordering multiple panels.
I might re-write this to a simpler one that where you will simply give the order of the panels in a string (2-3-4-5-0-1).

The mapper/mappers that I wrote can be found here
