Process from imagedata

[D4koon]

For my project it was easier to process the pixeldata directly so i added the missing functions in the wrapper maybe someone else needs that.

Ive added the possibility to pass a byte-pointer directly the downside is that is has to be decleard as unsafe.

Looks good, I don't have an issue with the unsafe code (we already have some unsafe code in PixData). However in this case using an IntPtr might be a better fit.

What's the actual use case here and is there any reason why you cannot use a Pix directly? I've had a bit of a look here and I'm not sure this is such a good idea as all tesseract does in this case is convert the byte data into a Pix object (see ImageThresholder::SetImage in the tesseract source code).

Maybe a few things you could consider:

• Someone dont need the image as a pix -> acomplish the same thing with less code is always a good thing even when it is used internaly anyway.
• Its an "offical" Api call why not integrate it in a Wrapper
• It should be a tiny bit more efficient because thers no need to interop with leptonica (to create the Pix). there might be more performance benefits. I did not look into it that much.

OK, I agree.
