I checked that first but I still got the same error (spelled correctly
this time).

>Which documentation? That keyword is not present anywhere in my copy

of ReportLab 2.0.

preserveAspectRatio=False ...

New post version 2.0: drawImage can center the image in a box you
This saves developers from doing lots of math in their code. You can
define a box with x,y,width and height. If 'preserveAspectRatio'
is set, the image will be scaled up or down as needed in proportion to
fit entirely within the box. Unless the aspect ratio perfectly matches
the box, this will leave some space. So, the boxAnchor property defines
how the image should be anchored in the box, using imaginary points of
the compass. 'sw' for SouthWest is the default, but 'c' for center
will center it in the given box.
