[Gdal-dev] How to scale an image

[Sonson Sonson]

Hi all,
I have a question. I would like to know how to scale an image. I am
writing a program where I need to scale an image before processing it,
but I cannot find any sample program, or documentation on how to do
that. Say if my image's size is 6579x3289 pixel and I want it to be
scaled to 6656x3328, can anybody point me to documentation and sample
codes on how to do it.

Thanks.
