This page covers some of the more advanced configurations for :ref:`Stream <stream>` and :ref:`Lattice <lattice>`.
Plot geometry
-------------
You can call Lattice with debug={'line', 'intersection', 'contour', 'table'}, and call `debug_plot()` which will generate an image like the ones on this page, with the help of which you can modify various parameters. See :doc:`API doc <api>` for more information.
Process background lines
------------------------

To find line segments, Lattice needs the lines of the pdf file to be in foreground. So, if you encounter a file like this, just set invert to True.

The scale parameter is used to determine the length of the structuring element used for morphological transformations. The length of vertical and horizontal structuring elements are found by dividing the image's height and width respectively, by `scale`. Large `scale` will lead to a smaller structuring element, which means that smaller lines will be detected. The default value for scale is 15.
Let's consider this pdf file.
