I have a JPEG "image" (actually a BLOB in a database) which I want to import/convert into a "Bitmap" structure in memory. The reason is that I use a third party library which is unable to work with JPEG images and I need to pass an uncompressed bitmap (as a pointer). All I found so far are ways to convert between different formats on disk but saving the image as bitmap first and re-import it will take far too long.
I don't know much about .NET but I think a System.Drawing.Bitmap should be able to hold the uncompressed data. I'm working with C# and Visual Studio 2008.
