Description Mathias_Bauer 2005-02-09 13:01:54 UTC 
Load the attached document doc1.sxc and scroll up and down. It contains OLE
objects that are drawn by painting their metafiles.

doc2.sxc contains the same metafiles, but inserted as graphics. Scrolling is
very fast here.

The difference is that in doc1 the metafiles are drawn in buffered mode, in doc2
not. I talked with HDU and from what he proposed I don't believe that the
buffering can be accelerated enough to make the scrolling acceptable in that
mode. Currently it's close to be a showstopper IMHO.

So IMHO the buffering should be removed for DrawOLEObjects (and their
counterparts in Writer I assume).

Comment 3 Armin Le Grand 2005-02-14 17:39:17 UTC 
AW: After the reason for #114233# is gone (now always metafiles get painted),
that buffering can be removed again. Problem was more to find a m76/m77 version
where i could add a chart at all. Adding sw now.
Comment 4 Armin Le Grand 2005-02-14 19:32:59 UTC 
AW: sw added. Doing changes to DrawingLayer. Checking them. Looking for the old
buffering change in SW.
Comment 5 Armin Le Grand 2005-02-14 21:11:48 UTC 
AW: Found change in SW, changing, too. Tested both thoroughly, works. Checking in.
Comment 6 Armin Le Grand 2005-02-15 14:17:03 UTC 
AW: Okay, done.
Comment 7 Armin Le Grand 2005-03-03 14:38:36 UTC 
AW->WG: Please verify. Both example files should now scroll the same speed.
