[gdal-dev] Python-GDAL - How do I create a GeoTIFF from this array?

[Javier Jimenez Shaw]

Oh, that is one step further.

There are two things:
 - the difference between center of the pixel and corner of the pixel (that
I was "reporting" in my previous email)
 - row from top down or bottom up.

Tiffs usually have the rows ordered top down. Technically can be also
bottom up, but it may be a problem with some software. It is a strange
thing. Avoid that.
In the top-down mode (that is the usual one), in the geotransform the pixel
size in the Y direction is negative, because the Y direction in the image
goes in the oposite direction as the CRS.
