IMO existing code, such as GDI+, will not do format conversions for you. Its matrix operations preserve the pixel format, all they do is multiply and/or add pixel values and matrix coefficients, not bit masking or shifting.

There are a few optimizations you could apply to your code; in particular you should avoid calling methods for each and every pixel (RGBArray.Length, SwapDWORD, ReadUInt32); replace them by local variables, local code, and larger moves (say a scanline at a time).

FWIW: languages that don't support pointers (such as VB.NET) aren't as good as C/C++/C# for image processing.
