 Visual Basic and image processing
There are a couple of good 3rd party imaging packages that can be used in VB or
delphi or C++ that do a terrific job with very little coding, but they can be
spendy.

The new VB.NET is supposed to have a new GDI+ package, expanded file format
support that greatly enhance VB's imaging capabilities, but VB.NET is still
several month from release.

It's definitely possible to do image processing in VB but like Fedor
mentioned it's anything but fast.
There's some examples on my page and quite a bit of source code too.
There's very few pages that have VB source code on for graphics programming
but you may want to check out these pages:

Http://www.shrinkwrapvb.com/
Http://www.vbaccelerator.com/
Http://www.vb-world.net/
Http://codeguru.earthweb.com/vb/

The latter site also has a lot of C++ source code, and the API related
graphics code for that can be converted to VB.
Hope this helps,

Such a thing already exists ...

In 1993 we decided that VB was too slow, syntactically too complex, lacked
the IP functions, and so developed PiXCL (a more or less self-documenting
interpreted language written in C/C++), and an IP and image format handling
DLL (in C), so it would be a quick exercise to acquire, display and process
images. It does all of the above and a whole lot more. PiXCL is now at
version 5.04 and had been very useful to us (and the kind souls who bought
it...).
