[gdal-dev] Overviews using GDAL

[HariPrasad]

Iam beginner to GDAL.

I have an Image which has internal overviews in it. I am able to display
each overview separately, but i want to dynamically select the corresponding
overview when that image is zoomed in/out. Which method i need to use in
GDAL to achieve this functionality.  And how does ArcEditor 10 understand
which overview to display.
