>You cannot. A workaround is maybe to keep references to all registered
handlers,
free the manager, recreate it and re-register all handlers except the one
you want removed.
Please file a bugreport (feature request) so a handler can be un-registered.
Thanks. I've tried that, and it works. But I saw that Lazarus is not
using these registered handlers, so it doesn't really help me.
For the record:
Om:=ImageHandlers;
ImageHandlers:=TImageHandlersManager.Create;
for i:=0 to Om.Count-1 do
begin
tn:=Om.TypeNames[i];
ext:=Om.Extentions[tn];
ir:=Om.ImageReader[tn];
iw:=Om.ImageWriter[tn];
if tn<>'JPEG Graphics'then if ir<>nil then
ImageHandlers.RegisterImageReader(tn,ext,ir);
if iw<>nil then ImageHandlers.RegisterImageWriter(tn,ext,iw);
end;
Om.Free;
Thank you Michael!
