In a print I made I noticed that my letters where mirrored.
And I would like to flip my XY axis on the projector, how do I do that?

Check out your projector's manual.

It's not really a projector (I only wrote that to use the same terminology NanoDLP uses).
I use a iPad-LCD driven through a displaydriver (not possible to do any settings).
I was looking for something found in Creation Workshop .... Flip X and Flip Y in the "Setup" section.

It takes some processing effort on rpi. I will try to add it without major performance hit. It is probably the worst place to handle the issue.
You can try flip function of your 3d design program before I could add it to nanodlp.

Ok, I see.
I might have found a solution ... in rpi : config.txt one could apparently add : display_rotate=0x10000
This should flip in X and to filp Y (mirror) one could use : display_rotate=0x20000
Makes me think that I could flip both using : display_rotate=0x30000
Will try it later today.
This would hopefully not strain the processor of the RPI

Good find, I doubt it will have any effect on rpi processor.

Fixes the mirrored text and all the webpage images but the slicer seems to ignore the resolution and slices portrait mode.

As long as you entered correct width and height on the setup page it should work. Slicer will initialize based on the setup value.

On win and lcd, no way to have mirrored images ?

UltraMon could do that on windows. You can mirror your pieces with your design program. It is something could be added to nanodlp but it have negative effect on performance.

I know on PI working with rasters negatively affects cpu performances, but on x86 mirroring, also from a shell, is very fast.
I can give a try using syscall to see what happens, if you implement something like [[CurrentRasterFileName]] or similar, otherway with only layer n is quite difficult to locate raster to process.
This can also open to raster compensation, if needed.

There are couple of ways to do that.
1. You can run separate service to watch plates/ folder for new files and process them.
2. On gcode box before layer use [[ExecReturn run.bat plates\[[PlateID]]\[[LayerNumber]].png]] (I am not sure how it will works on windows.)
3. On gcode box start [[Exec run.bat plates/[[PlateID]]]], watch folder for new file and rotate any new file.

Nice tip, I'll give a try, thanx
