[reportlab-users] Building/Storing PDF's in memory

[J. R. Carroll]

Hi Andy,

Thanks - that would be great.  I am currently using Canvas, but see myself
doing some platypus work very soon as I am generating quite a few reports.
 If you have examples for both that would help quite a bit, but if not,
Canvas is preferred.
