Thank you for maintaining this wonderful library. Currently I am mining pdf files consisting of curves which either have a stroke dash-array or with just a normal stroke (see image attached). From what I can discover in the source code this information is not parsed in the mining process.
Screenshot 2021-06-12 at 21 49 25. My question is if I am missing something very obvious that could help me determine this differentiation? If this is a feature that currently does not exist, would you be interested in a PR?

For this we need to extract the "Line Dash Pattern" from the graphics state as mentioned in Section 4.3.2 "Details of Graphics State Parameters" in the pdf reference.
