If I add overviews to a TIFF (as described here: http://gdal.org/gdaladdo.html
) the single file contains multiple images. Then if I do an
operation on the image with ImageMagick ('convert') I end up with
multiple images output. For example, if I have a file 'test.tif' and I
attempt to resize a smaller image ('convert test.tif -size 2048 -
resize 1024 test.png') I end up with multiple copies of the PNGs, one
command is run and output for each overview (test-0.png, test-1.png,
test-2.png, ...).
How can I select only one of these overviews? It would be best if IM
even selected the best overview for me. How can I do this? I don't
even know where to start looking in the documentation.
Thanks,
Seth
