I have created a proper GeoTIFF file with the code

The code sets the line/sample -- x/y affine transformation
using an array of 6 doubles. The code contains a conditional

Norman,
My apologies. The GCP projection is actually supposed to be passed as the
third value in the SetGCPs call - where you have passed the string
Richmond. Instead pass the whole WKT strings for the coordinate system.
Best regards,

I have created a geotiff file using the GTiff driver, and have
successfully set options for it to be a strips file with no
compression. Also, successfully called the functions

Norman,
I believe you want to call SetGCPProjection() instead of SetProjection()
when using GCPs instead of an affine transform.
Best regards,

Frank,
I am using GDAL
Version : 1.9.2
so maybe that is why I do not see the method SetGCPProjection().
I think you have convinced me, though, to calculate the 6 coefficients
directly,
and then call SetGeoTransform(). Will let you guys know how this works out
for me.
Thank you,
Norm
