Hi all,
I am currently thinking on how to handle pipelines in some of my application. By pipeline, I mean "something" in which I can set an input, add some processing on that input, and retrieve the output (the result of the processing).
If I am not clear enough, let's go with an example. Suppose I have an image, and I want first to crop it, then apply a filter on the crop and get the result in another image.
Does boost has a library with such a feature?
Best regards,
Olivier Hi,
those "Pipelines" are called streams in C++, and boost does provide a library for streams (boost.iostream). However, given this image-example I'd not recomend you to use streams for this as those require copying, proxy object or move-semantics. Moreover iostreams are not thought to pass whole objects, but little pieces of information instead (like chars). This doesn't mean that you can't use the operators << and >> for this though. You might want to look at boost.Proto to build a lazy evaluated expressions. If you really try to build such an Image-Library, look at boost.GIL first. Regards, michi7x7
