IndexError in slice.mesh_to_plane

[whoosher]

Hello, Thanks for your great work! I have some problem to use the stltovoxel library. During stl voxelization with 256 resolution, I encounter the problem concerned with indexError of slice.mesh_to_plane. I change the "def calculate_scale_and_shift" for size of bounding box (specifically, bounding_box[2] -> max(bounding_box) - slice.py, line 131.) I have tried to write the try-except sentence for exception handling because the little resolution change (256->255, 256->257) can be helpful to settle the errors. Can you help me?

PATH is my personal driver path

-------------------------Error--------------------------- multiprocessing.pool.RemoteTraceback: """ Traceback (most recent call last): File "PATH\lib\multiprocessing\pool.py", line 125, in worker result = (True, func(*args, **kwds)) File "PATH\lib\site-packages\stltovoxel\slice.py", line 54, in paint_z_plane perimeter.lines_to_voxels(lines, pixels) File "PATH\lib\site-packages\stltovoxel\perimeter.py", line 10, in lines_to_voxels paint_y_axis(lines, pixels, x) File "PATH\site-packages\stltovoxel\perimeter.py", line 48, in paint_y_axis pixels[target_y][x] = True IndexError: index 255 is out of bounds for axis 0 with size 255 """

The above exception was the direct cause of the following exception:

Hi @whoosher thanks for reporting the issue. Couple of questions: Which version of the software you are using? If you are using the version on PyPI could you try installing the version from this git repo using python3 -m pip install 'stl-to-voxel @ git+https://github.com/cpederkoff/stl-to-voxel@master' and trying again to see if that fixes the issue? If that doesn't work, would you be able to post the model and args you are using to help reproduce the problem?
