I thought I copied jpeg12_osgeo.dll as part of the PyPI build. I'll
reverify next week and rebuild if necessary to include it. You
shouldn't need to get anything special to use the Python bindings from
PyPI on windows (except if you want GDAL/reprojection support, which
requires linkage of GDAL -- OSGeo4W is the way to go in that case).
Thanks for the report,
Howard

Thanks for your response Mateusz. I think I got it working.
I located the jpeg12_osgeo.dll in the bin dir of Frank's FWTools,
made a copy and placed it in the Python path and liblas now seems to
import ok.
Not sure if that's the correct way to fix my problem but it seems to
work.
Thanks again.

Just tried to get v 1.2.1 (Downloaded from PyPi) up and running on

When launching from the cmd shell it looks like the dll that can't
be
located is jpeg12_osgeo.dll.
I had a similar problem with an earlier version caused by an old
libtiff.dll but that seems to not be the case here.
Any ideas?
Hi Jason,
From what you're writing I assume you have OSGeo4W package installed.
First, check if you have jpeg12_osgeo.dll installed in OSGeo4W
location.
Assuming it is on C: drive, the DLL probably is inin C:\OSGeo4W\bin
Now, try to add C:\OSGeo4W\bin to PATH environment variable, open
console and issue this command:
C:\> set PATH=C:\OSGeo4W\bin;%PATH%
C:\>python
import liblas
Does it work?
Best regards,
