While I understand your sentiment, I disagree with your conclusion. The original altTrans script was created for Ken Ray who wanted to use it on 32x32 icons, for which it was plenty fast. I also use altConvolve to create blur shadows for small buttons in ButtonGagdet. I consider both cases to be 'real world.'
My apologies, by 'real world' I meant all image dimensions, not just icons and thumbnails.
The demo I created (alluded to in the subject of this email), had a max size it could be used. I found it worked fine on all my computers with images up to the max size, and never did I see anything close to a 30 second wait time.
I modified the script and removed the size restriction. Then I loaded a photo that was 1024 by 768. It took just about 30 seconds to complete.
Again, the algorithm is there for anyone to convert to a C function and either 'shell' to, or create an external with.
Could you elaborate on 'shell' to? Since my experience with compiling C is proving to be difficult, a way to execute the script from the shell for faster results would definitely be an alternative.
As always, if you don't like it, don't use it.
Please understand, it was not my intention to offend. Your script is great, as most of your scripts are. I was just trying to show that Transcript needs to speed up for (large) image manipulation purposes.
Regarding the altConvolve fix, thanks for your comment and I'm very sorry I didn't get back to you. I only now found it in my email, and it does appear you have a good hypothesis on why the external doesn't work. Unfortunately, I'm not an external writer-- though I hope to create some simple ones soon, with tutorials on how they're done. Perhaps that's a good one to start with!
That's OK. :) I'm going to keep attempting to build the external with the resources that I have, but if I don't get it to work soon then I'll be dropping down $150 to have it compiled for me (definitely a loss when your software is free).
As far as a tutorial on building externals, it would be a wonderful tool to help with the furtherment of Revolution. Honestly I'd like to think the folks at Runtime Revolution are creating a tutorial or walk-through of some sorts. The Externals SDK contradicts the "Programming made easy" feeling that Revolution tries to promote.
