AW: [gdal-dev] Create gdaldataset from in-memory Image/Bitmap/byte[]/MemoryStream

[Felix Obermaier]

Tamas,

I just went through the gdal 1.7 release notes, and read that a function 'FileFromMemBuffer' was added to the csharp bindings.
Since I'm getting image blobs from an sqlite database (png), is it a suitable way to use that function?

Thanks
Felix Obermaier

Felix,

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

http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/GDALWrite.cs
http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/GDALDatasetWrite.cs

For more information about the raster IO operations in C# see: http://trac.osgeo.org/gdal/wiki/GdalOgrCsharpRaster

Best regards,

Tamas

Hello list,
