[gdal-dev] how to create just the msk file from a rgba vrt file

[Duarte Carreira]

Hi there.

Continuing with trying to cut processing times, I am trying to get a msk file from a vrt mosaic, without converting the entire vrt to tif just to get the msk file.

In other words, how can we create a msk file from the alpha band without rewriting the whole image?

Thanks again.
