When I use this function, then Preview window is open for specified effect in the chain: ImageEnView1.IEBitmap.EffectsChain.Edit
The problem is that the result preview is not displaying the actual image. It shows the result as if there are no other effects in the chain, but only one - the selected one.
For example, if in my chain the first effect is a change in contrast, and the second is a change in hue. I run the EffectsChain.Edit function for the first effect (contrast). In the preview, everything looks as if there are no other effects, only the change in contrast is displayed in the result.
But we must see the end result - the result of all the effects in the chain, and in the correct sequence!
