[reportlab-users] Reportlab and IronPython

[Robin Becker]

I suspect part of your problem may be that you're using latin1 as an encoding 
for the python.


We have made an assumption that all the strings we'll see in the print path, ie 
things that end up on the pdf canvas, will either be unicode strings or will be 
utf8 encoded byte strings. I see the error refers to u'\x93', but I don't think 
that's a legal character.

I did try out IronPython some time ago, but at that time I was unable to get it 
running. I don't think that was because of any of our extensions though.

It may be that you can do without the extensions as most of the code will run 
happily (if a bit slower) without them.

There are three main C extensions,

_rl_accel.pyd which provides fast operations for some of the reportlab internal 
operations. If omitted nothing serious should happen.

_renderPM.pyd which implements a canvas like object for drawing charts/lines etc 
etc.

sgmlop.pyd an sgml type parser to be used with paragraph tags; if omitted the 
paragraph xml may become a bit more xml like ie things like naked ampersands 
will not pass without error.

In addition when we use images other than jpg we need to use PIL the Python 
Imaging Library to do conversions of various bitmap formats into simple RGB.
