I'm reading pixel values (RGB) from a bitmap object using function from
system.drawing namespace & vb.net (.net framework 1.1)

But I would like to make it faster, so is there any another way of reading
pixel values from bitmap objects? (some API or smthng)

Eric Gunnerson wrote an article called 'Unsafe Image Processing' that
covers use of Lockbits() for dealing with pixels in a bitmap. check:

Eric refers to C# but the concepts are the same.

If you wanted to dive deeper, you could check Pinvoke.net for info on
accessing DibSections.
