You can find examples in the gdal source tree about creating a dataset and
write data by using the WriteRaster method:<br>

<p class=MsoNormal>Hello list,<br>
<br>
I'm using GDAL via swig C# bindings. Is there a way to create a gdal dataset
object from an in-memory Image/Bitmap/byte[]/MemoryStream, and if so, how
can I achive this.<br>
<br>
Thanks in advance<br>
<br>
