[reportlab-users] Report lab/PIL and py2exe

[Larry Bates]

It definitely has to do with the fact that PIL does 
some "funny" dynamic loading of the plug-ins for each
different graphic format.  I supposed that ultimately
it might be considered a "PIL" problem but if I am
using PIL in my main program, I can just import the
appropriate plug-ins manually at the top of my 
program and it "fixes" the problem for py2exe.  Inside
of ReportLab this doesn't work.  I must go all the
way down into the module that is importing PIL and
insert the imports manually into that module (which
is sort of a "ReportLab" problem).  Changing code
down deep in ReportLab always makes me uncomfortable
because it makes doing version updates much more
painful.

I would suggest that being able to reliably "freeze"
a program that includes ReportLab/PIL with py2exe is 
a very good thing (it is very important for distribution).

The simple solution is to just import all the plug-ins.
I may not be terribly efficient, but it does fix the
problem easily.

I don't know enough about this.  Is the problem with
PIL's "lazy loading" and needing to help py2exe
detect which PIL plugins should be included in the distro?
If so I'd argue it's a PIL problem.  If not, can you
explain why this works in the file system and not in
an EXE?

It's obscure, but we are very concerned with packing
whole apps in compact distributions, so it's certainly
worth getting to the bottom of it...
