Drawing with lines is split in hundreds of stroke images

[4security]

Describe the bug
I try to export my stylus drawings as flatten images and every stroke is saved
in multiple files and not one big one.
The ink is in "drawing", not "handwriting" mode

The export fails if I add vertical line to the file
Stroke.zip

To Reproduce

1. Open the file, unzip and import in OneNote
2. Ensure that the drawing is "drawing-ink-mode"
3. Open the .exe
4. Select the notebook
5. Export as MD
6. Look in the resource folder and you see the splitted files:

6. Remove the line
7. Do steps 2 to 5 again

Expected behavior
Render also with lines

Export of handwritten notes is not supported

[4security]

I already know that handwritten notes are not supported - but this awesome tool exported ca 30 drawings and writings correctly. You can choose in OneNote to create ink "as drawing" or "as handwriting" and drawings are flattened as an image.

I exported my notes with 80 % with this tool and 20 % via Evernote Export (most drawings).

I would close the bug, but I think maybe some investigation could help to make it to an "all-in-one"-tool.

Hey @liquididea , indeed I have noticed that evernote is doing great with handwriting. I will investigate once I have free time. Thank for the detailed report. Maybe I will come back to you if I need some additional details.
