[Fu Chen]

Hi!
GdalWarp doesn't work when i try to convert a image into lcc project.

the source image is

=================================================

I can use gdalwarp to turn it into utm's other zone, and can see the diferent in size and image content.
I don't know why lcc doesn't work. 
Do I miss something?
