[reportlab-users] fixed paragraph height?

[Marcel Gsteiger]

I now added a new flowable in flowables.py:

class VertAlignBottom(Spacer):
    """Use up vertical space so that only a given space remains"""
    def __init__(self, height):
        self.height = height

    def __repr__(self):
        return "VertAlignBottom(%s)" %(self.height,)

    def wrap(self, availWidth, availHeight):
        if availHeight>self.height:
            return (availWidth, availHeight-self.height)
        return (0, 0)

....this did the trick.

The opposite would be to "extend" a paragraph to reach a certain
height (quite interesting operation ;-). I imagine the UseUpSpace
flowable (bug report: no docstring ;-) fills a frame down to its
bottom. Maybe you try that one?
