[REBOL] Re: convolve effect

Hi Pekr,
<< Well, long time ago I asked about the feature. My friend suggested me
that general native matrice operations could be used for many
computational stuff, but I am no math folk, so I don't know if it would
help. >>
Yes, that's the idea. I'm not a math person either, which is why I'd prefer
to have RT do it. :)
<< - Added "func" effect. This allows you to call a REBOL function from
within the effect pipeline, manipulate the current image (including
its alpha information) and pass an image back to the effect pipeline.
Is that what you are asking for? >>
That's a great feature too, but I think for the matrix operations, REBOL
functions will still be very slow if we have to pick/poke values.
<< Or do you mean operations upon image
datatype directly? Now another question popped in my mind - are Core and
Command users left behind? What do I mean? Core and Command both know
image datatype. But they don't know of face composition. How can we work
with images using Core and Command? Hmm, shouldn't datatype manipulation
functionalities be part of the kernel of the system? >>
It should work for Core and Command as well. It has nothing to do with
displaying the images, just manipulating the pixel values in them. I haven't
looked into it, but I wonder if there's a similar way to deal with audio, to
create audio compositing functions? It doesn't matter what the data is, it
may just be raw data (GIS or simillar) that you want to perform the
operations on.
