Description clippka 2005-09-14 15:31:40 UTC 
In OOo 1.x, graphics where removed from memory at most 20seconds after they
where not visible any longer. Currently a graphic that was rendered once is
never removed from memory until the document is closed. For documents with huge
graphics on multiple slides, this leads to huge memory footprints.
Comment 1 clippka 2005-09-14 15:34:07 UTC 
To reproduce this issue

- Load a document with multiple slides and huge graphics on each slide
- Look at the current memory footprint (f.e. tast manager under windows)
- Travel through all slides

You can see that the memory footprint grows but never shrinks.

For QA, please test images like png/jpg/tiff but also metafiles, since it looks
like metafiles where never swaped out, even in OOo 1.x. This must be fixed with
this issue also
Comment 2 clippka 2005-09-14 15:36:14 UTC 
@cl->ka: there are three problems here

1. swap out does not seem to work, I don't know how to debug this
2. swap out for metafiles does not work since in SdrGrafObj::ImpSwapHdl there is
an optimization not to swap out graphics with a size < 20480 bytes. But for
metafiles this is not implemented and they always report 0 bytes.
3. swap out does not work in slidesorter since the slidesorter caches the view
object contacts.
