Sorry about causing this frustration. I just consider it pretty important to not restrain the image processing to one thread when even laptops have 4 cores these days. Please attach a zip of the source code here and a modification to the Minimal skin or project that makes use of your filter so I can quickly reproduce the problem.
As I'm on vacation, I can't promise a super fast resolution to this, but I'll try.
First: I hope you're having a good holiday.
Second: Don't worry about looking at this on holiday. It's not
that big of a deal!
Third: I am going to test if the other filters do actually work okay because I did see some oddities with the other filters that I don't recall seeing in the older versions. What I'll do is run the same settings on the older version and the newer version.
Fourth: As for uploading would it not be easier for both of us if I just linked to you my skin and then uploaded the source code here of the one filter (I could do the others but I imagine if we can figure out what the problem is I can make the others work). This way you have the settings available and all the features. My skin actually isn't all that complex but there are a lot of options to the filters.
Fifth: As for the JavaBean specification I did update the ReflectionFilter and it still doesn't seem to work (the problem is the images aren't mirrored - I just see the original image; please note that my skin allows for having just the original image or - the default - showing the original image and the mirror image in the direction - or directions - of the mirroring).
Six: What's strange is the TranslucentFilter does not follow the specification but this one does work but maybe that's not needing state; I don't know.
Seven: Yes laptops have 4 cores at the least but is it possible to mark some filters as using one? I didn't think it needed state but maybe it does anyway (at least with only the simplest configuration - the filters can be chained together for different effects).
Please let me know about the upload of the source code and the skin as I think that would be the better way to go about it as it has all the features configured (it'd take a while to get it to work in Minimal skin) and you can see for yourself how it works. Then I could just upload the one filter here for you to look at (I show the source code for the skin but not the filters in the skin directory).
Thank you for the reply, be safe and have a great remainder of your holiday! We can talk about this when you're back.
Cheers.
