FadingGroup_AssignImageOverlay

function

Delphi
procedure FadingGroup_AssignImageOverlay (FadingGroupId: LongInt; ImageOverlayIndex: LongInt);
C++Builder
void __fastcall FadingGroup_AssignImageOverlay(System::LongInt FadingGroupId, System::LongInt ImageOverlayIndex);
C#
public void FadingGroup_AssignImageOverlay(int FadingGroupId, int ImageOverlayIndex);
VB.NET
Public Sub FadingGroup_AssignImageOverlay(FadingGroupId As Integer, ImageOverlayIndex As Integer)
C++/Qt
void FadingGroup_AssignImageOverlay (int FadingGroupId, int ImageOverlayIndex);

Assigns the image overlay identified by ImageOverlayIndex to the fading group. The overlay then fades (alpha modulation) in synchronization with the other members of the group.

A given overlay belongs to at most one fading group: assigning it to another group removes it from the previous one.
