This example shows how to load an image into the BITMAPHANDLE, then convert the BITMAPHANDLE into a RasterImage.

I've updated this project to use the LEADTOOLS v17.5 in VB.NET using Visual Studio 2008. Copy the "Test.jpg" file to the c:\ drive to test the project without modifying it.

Updated to LEADTOOLS v19 with Visual Studio 2017. Also changed project to automatically select dll's for running in 32-bit and 64-bit.
Extract to "C:\LEADTOOLS 19\Examples\DotNet\CS\" to use the example.

Uses Visual Studio 2010 (v100) compatible CDLL toolset found in "C:\LEADTOOLS 19\Bin\CDLLVC10\", chooses "Win32" or "x64" subfolder automatically.
There is no longer an included "Test.jpg", instead it uses "cannon.jpg" from the "LEADTOOLS Images" folder.
Changed conversion method to use an intermediate of Windows device independent bitmap (DIB). First converts the BITMAPHANDLE to a DIB via L_ConvertToDIB(), then converts to a RasterImage via RasterImage.FromDib()
