Hi, Partially inspired by this thread : http://tetrisconcept.net/threads/ctwc-stream-transparency-cropping-effect.2659/ I had a crack at knocking up a script to sample the playfield area (as a few others have done) and dump the output as text; essentially just to see how fast certain areas of the Windows GDI could cope. It worked reasonably quickly, so I thought I'd play around some more and do the same thing with some live input. Long iterative story short, I've been playing around with a writing a program that "may" be useful/interesting to people. There's a lot of tidying up and features that I'm interested in implementing for fun, but I thought I'd see if anyone had any use for it in it's current state. Rather than attempt to explain it with pictures, I did some quick messing around here: Essentially it's just sampling an area of the screen, dividing it into a grid and taking one or more pixels from each grid square. The detection/rendering parts are swappable, the idea being you can dump custom logic into the detection and subsequent rendering/output (e.g. dump it to a window, encode to a gif, output Fumen - I haven't written those yet). There are a number of shortcomings/refactorings, and optimisations to be made (e.g. Note the greatly improved capture speed when disabling Windows Aero), but if it's currently useful to anyone, I'm happy to throw up the source.
