Not able to create anything

[sanjaysswami]

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

~/sanjay_ws/src/aruco_generator/OpenCVMarkerPrinter$ python MarkerPrinter.py --aruco --file "./aruco.pdf" --dictionary DICT_ARUCO_ORIGINAL --marker_length 0.07 --marker_id 0 --border_bits 1
Save ArUco marker with parms: {'pageBorderX': 0.0, 'borderBits': 1, 'markerID': 0, 'pageBorderY': 0.0, 'fileName': './aruco.pdf', 'markerLength': 0.07, 'dictionary': 'DICT_ARUCO_ORIGINAL'}
Traceback (most recent call last):

Can you provide your environment? and use pip list to list your packages...
I am trying to reproduce the problem...

It seems old pycairo surface do not support enter attribute,
that mean it do not support with as statement.
I will try your pycairo version, my pycairo version is 1.18.1

[cyberbeat]

Thanks for the hint, it works with newer pycairo version. Would it be possible to split single markers into multiple DIN-A4 pages? So that you could cut and paste the papers? Possibly splitting at the bins of the marker?

Already done, you can read readme😀,
Both gui and command interface indeed provide parameter to do that.

If you are using consumer level printer, 
you will suffer from not able printing too large marker, 
so just set chunks shape at the GUI subSize entry before saving the marker to files, 
it will divide output marker to chunks. 
If you are using command-line interface, 
just add --sub_size_x x --sub_size_y y as parameters.

No, I mean to split a single aruco marker (no board). This would be to print large single markers, which need to be recognized over great distances.

pip3 install pycairo --upgrade
This will resolve this issue
