<div>Is a newly created raster band initialized to zero? If not,
is there some trivial way to perform such an initialization
(this is a MEM driver raster, if that matters).<br clear="all">

<p>This might be indeed driver dependent. Drivers will generally
initialize to zero or the nodata value. As far as I can see, the
MEM driver uses calloc() to initialize the buffer, so that should
be zero. Otherwise you can use GDALRasterBand::Fill() to
initialize at the value of your choice</p>
