Our two competitors MS Office/WPS do not have the problem of scaling.
Opening a document with 100 slides makes little percetible difference
from opening a PPT of one single slide. We take a look at the code, and
we think, maybe, instead of importing the document slide by slide, would
it be possible to import all the slides at once with multiple threads?
Has anyone made such attemp? What stops us from using concurrent processing?
Looks like this is what
https://git.libreoffice.org/core/+/8062e88e73acd8d1f9a62b0bd519b499693285e3
recently did for ODF case, it seems?
Here are the code snippet, in oox/source/ppt/presentationfragmenthandler.cxx
void PresentationFragmentHandler::finalizeImport()
{
...
int nPagesImported = 0;
for (sal_Int32 elem : aRangeEnumerator)
{
if ( rxStatusIndicator.is() )
rxStatusIndicator->setValue((nPagesImported *
10000) / aRangeEnumerator.size());
importSlide(elem, !nPagesImported, bImportNotesPages);
nPagesImported++;
}
...
}
