Bug ID: 97662
Summary: CPU burned re-compressing JPEGs to make them bigger
...
Product: LibreOffice
Version: 5.1.0.1 rc
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Printing and PDF export
Assignee: [email protected]
Reporter: [email protected]
It appears that our heuristics to avoid image de-compression and/or
re-compression could use some improvement. The re-compression is particularly
expensive since we not only jpeg but also png compress the result - cf.
pdfwriter_impl2.cxx. Also it seems we re-compress jpegs we just de-compressed
potentially at a higher 'quality' - thus carefully preserving any
de-compression artifacts, but not adding quality; not ideal - and very slow
with it.
