[FWTools] Recreating some of gdaltindex functionality in gdal python

[David Fawcett]

I am interested in building a python function to create a polygon
'wire frame' feature class based on the footprints of raster images.

In looking at the docs for gdal python, it looks like using
getGeoTransform, I can get the origin and the transform information.
Is there an existing function to get the coordinates for the four
corner points (like that reported in gdalinfo)?  I assume that I will
need to calculate this myself, but I thought that I would check first.

Thanks,

David.
