Wow, that works great  :D - the shift+mouseclick on the foreground image green background (or blue background) to set the hue/saturation/light values almost nails the effect first time - it's just a little adjustment here or there and it's almost perfect.

Your library is amazing.  I just need to get this integrated into the 5dpo webcam stuff now and published on github.

Thanks again!

You're welcome.  :)

Notice the HueDiff function, which is useful if the background color is red, because then it ranges for example from 0 to 100 and from 65535 to 65435.

You may also consider using BGRAToGSBA instead of BGRAToHSLA. You might get a better result, but it is slower, so probably not adapted to this.

Hi Blacksheep,

Sorry for prodding you a bit, but any news on the integration/publication of the source code? I'd think such a project would be a great advertisement for Lazarus...

Note: I'm probably not going to use this code myself soon, and I understand if you need to polish some stuff etc, but I think having it out there would be very interesting for a lot of people...

Thanks,
BigChimp

Hi BigChimp

no problem with the prodding - I must admit have been feeling rather guilty on this front - circular has done wonders with this library and it will be good to show off some of the more unusual features of functionality within it (especially as he found/fixed some issues whilst trying to help me). 

Unfortunately, I've been tied up with work commitments recently (I'm changing job and have trying to get certain requirements for that out of the way) but will get back to this particular piece of work as soon as I can.

I understand. Good luck on the job front and we'll see it when it's done ;)

We all have things to do apparently. Well, it's still better to have something to do, right?  :)

I was thinking about guilt in this context. Guilt means that we do something that is negative. But you don't. You think that you haven't done something positive, that's neutral. It's neither positive neither negative. So it does not make sense to feel guilty.

If you can do things, it will be positive, and we would be grateful. If you can't, that's neutral, it's ok.

I suppose it's rather about choosing how to organize time.

You're a great philosopher.

Oh that's nice.

Well I do not have enough time now, but that's a good idea.
