I modified the color curve demo to be able to add layers.
If i load an image and change the curve, the image gets darker or lighter. now if i add a layer and assign the imageenview, when i move the point on the curve, only the selected layer (new one) gets modified. the background stayed the same as it was before i loaded a new layer.
I thought that all the layers should be modified but i guess not.
Is that the normal behavior ?
Thanks

Hi Pierre
Yes, because ImageEn treats each layer as a separate image for the purposes of editing. You would need to use the ApplyCurve() method to assign the changes to each layer.

| Thank you. so let me ask you another question. I have not tried yet. If i modify the curve in layer 0, add another layer and then modify this layer too. it looks like layer 0 still show the original modification. now if i select back layer 0, i assume the curve does not go back to its original setting, the one I had before i created the new layer ? |

Hi
The layer should be same as when you last modified it. Is that what you mean?

| yes, that is what i mean but the curve will not revert to the state that created the modification when you switch back to the original layer. No worry, let me play with that. |

Try this:
procedure TFormCurves.ImageEnView1LayerNotify(Sender: TObject; layer: Integer;
event: TIELayerEvent);
begin
if event = ielSelected then
begin
ImageEnView1.LayersCurrent := layer;
IEColorCurve1.AssignSource(ImageEnView1.IEBitmap);
IEColorCurve1.ResetAllCurves();
end;
end;

Actually to apply the existing curve to a layer try this:
procedure TFormCurves.ImageEnView1LayerNotify(Sender: TObject; layer: Integer;
event: TIELayerEvent);
begin
if event = ielSelected then
begin
ImageEnView1.LayersCurrent := layer;
IEColorCurve1.AssignSource(ImageEnView1.IEBitmap);
end;
end;
This will apply the curve to any selected layer.

Hi
We'll do some work to improve the color curve handling with layers for the next release.

Hi
I investigated this today. TIEColorCurve is only using the TImageEnView for previewing, so it is correct for it to output to the active layer. You should use the LayerChange event of the TImageEnView to ensure the color curve is relevant to the selected layer.
I will improve the documentation.
