[gdal-dev] [gdal-1.8.0] Get new Coordinates from Geotiff avoiding black area

[Luiz Motta]

Met,

I made a QGIS's plugin where calculate the 4 corners of polygon with
the real pixels inside. Maybe is useful for you.
The name of plugin is "Image Boundary", The source is Python and use
only GDAL library for process.

Best regards,
Luiz Motta
