TImageEnView.UnlockUpdate
Declaration
procedure UnlockUpdate();
Description
Re-enables all calls to the
Update method, after a call to
LockUpdate.
LockUpdate and UnlockUpdate are useful, for example, when you need to resample multiple layers.
UnlockUpdate decreases
LockUpdateCount and calls
Update when the count reverts to zero.
Example
ImageEnView1.LockUpdate();
for i := 0 to ImageEnView1.LayersCount-1 do
begin
ImageEnView1.LayersCurrent := i;
ImageEnView1.Proc.Resample(300, -1, rfNone); // without LockUpdate this call resizes all other layers
end;
ImageEnView1.UnlockUpdate();
