[Gdal-dev] merge 3 tiff files into RGB color composite geotiff

[Gillian Walter]

Hi,

Sometimes I've found that I have to use the option "INTERLEAVE=PIXEL" 
when creating an rgb tiff in order for other applications to be able to 
view it.  I don't know if that could be the problem here (I usually get 
tag warnings, but the image still comes up).
