# Automating PDF Annotation

See [[portable-tools]] for valid dependencies.

## Extract Bluebeam Markups

Right now I'm exporting Bluebeam markups to csv before processing,
however if I converted to the code to extract the markups directly with MuPDF.Net
as I've managed before with itext, that could save a step.

## PDF Content Positional Tokenization

Recursively parse and consume pdf vector content.

> [!example]
> A span with text "GFCI" is consumed.
> (draw calls are removed from page content)
> A `gfci_label` token is created
> and encoded with the span's position.

> [!example]
> A `duplex_receptacle` token and a `gfci_label` token
> in close proximity are consumed
> creating a `duplex_gfci_receptacle` token
> which inherits the `duplex_receptacle`'s position.

```
