I have several questions relating to automatic compression, which come to the fore as I’ve tried to efficiently print out documents, and/or pre-existing PDFs, into smaller files.
I have 1.6.2, and note that the compression setting is "automatic"
1. What is that, exactly? The user manual doesn’t provide a clue
2. How does compression of the Text or JPEG, inside a PDF, relate to DPI? Why isn’t there a DPI setting?
3. When I have tried to print out large-file-size PDFs, using PDFCreator, the printed file is no smaller than the original. Does this have to do with the AutoCompression setting? I try to view and then print out files which are scanned and emailed to me, and have file sizes which approximate 1-1.5 Mb per page! All in an attempt to reduce that to less than 100k/page.
4. Why is DPI resolution only available for setting when the compression is not automatic, -and- there -is- resampling
5. What is the difference between downsampling and “average downsample”
6. What is “Zip”, in the compression area ?
