katana.units.pdf.pdf2text — pdf2text

Convert PDF to Text

This unit retrieves the text included in a PDF document, using the “pdftotext” Python library.

The unit inherits from katana.unit.FileUnit to ensure the target is a PDF file.

class katana.units.pdf.pdf2text.Unit(*args, **kwargs)

Bases: katana.unit.FileUnit

BLOCKED_GROUPS = ['pdf']

PDFs shouldn’t come out of this. So no reason to look.

GROUPS = ['pdf', 'pdftotext', 'pdf2text']

These are “tags” for a unit. Considering it is a pdf unit, “pdf” is included, and the name of the unit, “pdftotext”

PRIORITY = 25

Priority works with 0 being the highest priority, and 100 being the lowest priority. 50 is the default priorty. This unit has a high priority if this is detected…

RECURSE_SELF = False

Again no PDF from this. So recursion is silly.

evaluate(case: Any) → None

Evaluate the target. Extract the text out of the PDF document and recurse on any newfound text.

Parameters:case – A case returned by enumerate. For this unit, the enumerate function is not used. Returns:None. This function should not return any data.
