**Summary** Allow registration of a custom sub-partitioner that extracts images from a DOCX paragraph. **Additional Context** - A custom image sub-partitioner must implement the `PicturePartitionerT` interface defined in this PR. Basically have an `.iter_elements()` classmethod that takes the paragraph and generates zero or more `Image` elements from it. - The custom image sub-partitioner must be registered by passing the class to `register_picture_partitioner()`. - The default image sub-partitioner is `_NullPicturePartitioner` that does nothing. - The registered picture partitioner is called once for each paragraph.
Example Docs
The sample docs directory contains the following files:
example-10k.html- A 10-K SEC filing in HTML formatlayout-parser-paper.pdf- A PDF copy of the layout parser paperfactbook.xml/factbook.xsl- Example XML/XLS files that you can use to test stylesheets
These documents can be used to test out the parsers in the library. In addition, here are instructions for pulling in some sample docs that are too big to store in the repo.
XBRL 10-K
You can get an example 10-K in inline XBRL format using the following curl. Note, you need
to have the user agent set in the header or the SEC site will reject your request.
