@dogod621 I tried to run your code but I am getting the following error. Can you please help me with this?

AttributeError: exit

The 9x6 charuco board generated by MarkerPrinter is different from what OpenCV expects. In particular, the top-left square is white, while OpenCV expects a black square first. This means that OpenCV will be unable to detect the Charuco board.

Full description, sample code and workaround (for the time being) can be found here: https://github.com/rsnitsch/opencv-MarkerPrinter-wrong-charuco-board

Hello,

First of all, thank you for the great GUI!
Would it be possible to adjust the charuco board generator to have the chessboard corners always on as the outside corners?
This allows to have the same grid that is generated with the "CharucoBoard_create" function.

Best,
Romeo

Currently, the page border color is set to gray. Is it possible to set to change this?

Currently it is only possible to split aruco boards into chunks. It would be nice, to be able to split single markers into chunks. Then a thin cutting border would make sense for each page.
