Hi Akash,
Your example controller code seems good and shouldwork. The issue is that
PISA is a bit sensitive and only supports a reduced subset of CSS. The
error suggests PISA does not know how to handle "Alpha(Opacity=0)". You
will need to somehow strip out the unsupported CSS from the html before it
is rendered by REPORTPISA. Note that images are also problematic (you will
need PIL installed if you want anything other than JPG and even then they
are rendered in separate paragraphs), so you might need to play with this
too.
Cheers
Russell
