Derek:
Let's put it differently. My real interest is in seeing how to optimize
Rev code to access arrays in general, and image data in specific, as
rapidly as possible.
If I wanted to code a DLL to do the processing, I know how to do that
(theoretically). I was looking at Rev as a way to write portable code
(in Rev).
So, if you want to port my Rev code to C, please feel free to do so, but
it would not be solving the original problem I wanted to solve
(optimizing Rev code).
Thanks again!
:)

First off, thanks for your help.
Not a problem.
Secondly, why convert it to C? I have already written it in
Delphi/Pascal. The whole point was to make something that was
cross-platform. If you create an external on your platform (Window?
Mac), would it automatically work on the other platforms?
The external I make would be for Windows, but I hope releasing the
source will allow someone on another platform to port the code.
As far C, it's the only way I know how to make image commands and
functions for Revolution that are fast enough to consider using in
commercial applications.
Thirdly, the code I wrote is not at ALL how I wrote it in Delphi: the
extra loops to transfer the image data to the R/G/B arrays were not
necessary in Delphi (and perhaps not in Rev!).
If it's possible to convert Delphi to a Rev External then that would
be a solution, but I know nothing about Delphi.
Speaking of which, would a new feature for Rev, like
"repeat for each pixel in imagedata..." be one way to speed image
processing up?
be helpful for anyone else?
I think it would be helpful, but still rather slow. Submit it as an
enhancement on RevZilla. If people want it they will vote for it.
