in work.
Comment 4 bettina.haberer 2001-07-17 14:53:40 UTC 
When exported to ppt in the 632, the filesize has decreased to 19 KB, after re-
save in Power Point the size is 14 KB. ->Sven: It is known, that there are 
differences between Impress and Power Point concerning internal handling of 
contents at saving. But how is above mentioned decreased filesize compaired 
with the filesizes in Jonathan´s description explainable?
Comment 5 sven.jacobi 2001-07-31 17:15:08 UTC 
Here a short explanation of the file sizes:
The original Impress presentation has a size of 238kb and is much larger than 
the correspondent PowerPoint variant, because the document includes some unused 
ole objects that are not saved to PowerPoint. This will not happen in an actual 
version. Our new xml file format creates a presentation that is 11kb.

The OO version 609 creates a PowerPoint document of 76kb because in that 
version is a bug that leads to document preview graphics of a minimal size of 
64kb. That is fixed now, so that in an actual version the document is 19kb.
(76Kb - 64Kb old preview graphic + small preview of about 7Kb = 19kb)

The 19Kb document will be smaller when it is resaved by PowerPoint because they 
remove the preview graphic. ( I do not know why they do this and how this could 
been prevented ).
