Project description


OCR-D framework - file format APIs and schemas


Adding user methods to the generated PAGE API

Let's say you want to add a method get_FirstTextRegion on the pc:Page element:

  1. Create a file ocrd_models/ocrd_page_user_methods/
def get_FirstTextRegion(self):
  return self.get_TextRegion[0]
  1. Edit ocrd_models/ and append to the METHOD_SPECS list:
  # ...
  _add_method(r'^PageType$', 'get_FirstTextRegion')
  # ...

If the filename (sans the .py extension) does not match the method_name, you can provide an additional file_name attribute to _add_method:

  # ...
  _add_method(r'^PageType$', 'exportChildren', 'exportChildren_PageType')
  # ...

Would add the method exportChildren from a file

NOTE The method name in the file must match the method name passed to _add_method. This is not checked automatically, so double-check manually!

  1. Regenerate the PAGE API:
make generate-page
