Re: [gdal-dev] Re: gdal_rasterize output off by one pixel/cell
Thanks Even for making the fix! Is there documentation anywhere for how to apply changes like this? I apologize but I am just getting into this type of development. I thought I was able to install the latest nightly build today, but I'm not sure. Running Mac OS X. If anyone has any pointers I would really appreciate them off-list.

Re: [gdal-dev] gdal_rasterize output off by one pixel/cell
Eli, I finally got around to looking at the example shapefile and running the same operation on my machine, and it does indeed seem like the same bug. Thanks for the good eye, this almost seems like two separate issues; first being the missing edge points and second being the weird offset. I only say this because the offset persists even when I set the extents of the output raster as larger than the input layer.
