@Elwood

I'll just say a thing about choice and all that.

Hello Vicente, i've sent you a PM.

@Ami603
You surely have more interesting things to do after 6 years since release of ZDR, but are you open for suggestions/reports , or maybe you can upload sources somewhere on some github, so it can be improved ? (and to have more compositing based example source code good too)

Why i ask, its because it seems quite tasty stuff to use together with odyssey when you watch a videos and setup call to ZDR via context menu.

For example will be good to have ability to disable that image in center when you run ZDR. Also made zooming back go to original size (currently when you run ZDR, its from start zoomed a bit, and when you tries to zoom back to original size you can't, and only way to have original look is to exit from ZDR). Also will be of good help is ability to choice what control are : mouse or keyboard or both at the same time.

So for odyssey we can disable then image, set let say keyboard control (so when one move by ancident a mouse picture didn't moves) and when go to video page, RMB, choice "compositing zoom" and via keyboard control position and size.

I surely can donate 20-30$ to show some support.

@All
Vicente was kind enough to share sources of ZDR tool and allowing me to upload them on github, so we all can improve it if need it as we want.

Thanks again!

@kas1e

The important part about compositing is inside gui.c, but please ignore comments from some functions as these may be leftovers from other tools

@kas1e

It really should be a best practice for all AmigaLike system programmers.

@Ami603
Well done! Thanks for sharing your code and efforts.
