[reportlab-users] Adjusting flowable position

[Andy Robinson]

The easiest way to do this will be by writing your own Flowable class.
 It needs a wrap() method to return the desired size in the story, and
a draw() method to draw the bitmap and the line (and, possible, any
other key strings like 'Signed: ___' ) wherever you want.

Look in reportlab/platypus/flowables.py at the class XBox, a
super-simple custom flowable which draws a box with two big diagonals
(we had the name before MIcrosoft did!).  This should be an easy one
to copy and adapt.

Hope this helps...
