[api-dev] Re: using external libraries with Pyuno components

2011-03-17 Thread J├╝rgen Schmidt
Hi Paolo,

i don't know, i am still no Python expert :-(

But maybe it is possible to expand the sys.path variable with a
directory in the oxt package. Something like

OXT_DIR = 'oxt_root/external/'
import sys
if OXT_DIR_DIR not in sys.path:
sys.path.append(OXT_DIR)


If it is not possible, it sounds like a useful enhancement ;-) The
question is would be who can make it and when ...

 Hallo,
 
 I'm developing a tool in python that perform some very basic image
 manipulation.
 The tool uses the Python Imaging Library (PIL)
 
 Now I would like to integrate my tool in OOo as a pyuno component, but
 PyUno comes without the PIL library
 
 Is there any way to deploy such a dependence inside my extension?
 
 or as an alternative: perhaps pyuno contains a module/library providing
 some basic (raster) image manipulation functions?
 
 thanks for any help

Hi paolo

long time !!!

i put my imported .py file inside the extension in a pythonpath directory

the main .py files are at extension root

i found this information long time ago and think it is a reserved
directory name

no declaration in manifest.xml

HTH

True, I was aware of this feature and I'm already using in order to 
split my pyuno components in more modules.


Actually I've expressed my question very poorly.

The fact is that Image library (PIL) looks quite complicated.
It contains python modules beside c code that is platform dependent.

so I'm not sure of the path to follow in order to compile and include 
the library in my extension.


Perhaps I should address the question to PIL authors/mantainers...

However, if there is an alternative for not using that library I'd be happy.

In substance I need to load an image (*.jpg) and with a nested cycle 
(rows / columns) I need to look for pixels having certain colors.


After that, I need to clip the original image in many thumbnails

Perhaps is that possible using OOo API's ?

ciao
Paolo M
