After reading bug 80855, i see that exporting the entire document as pngs or jpgs is not possible, so i'd like to suggest that when the dialog appears to specify the output size of the images, that it be given the same range options found in the print and pdf export dialogs.
That would be a great feature.
Before exporting, all fields should be refreshed:
I think, this is right now not done (p.e. at PDF export)
If you need a workaround for now, try exporting the document to PDF, then using ImageMagick to convert each page to PNG.
ImageMagick has the helpful 'convert' command that can do that for you on the command line:
(BMC.pdf was produced from a 2-page BMC.odt)
qubit@lo:~/$ convert BMC.pdf BMC.png
BMC-0.png BMC-1.png BMC.pdf
we want to give our end-users a good user experience, so it's important to receive the first page fast. The end-user doesn't care, if a 100page-export needs 60 or 65 seconds, but it's a big difference, if the first page comes after 2 or after 7 seconds.
So it would be great, if the first page is exported as fast as possible.
This "all-page-png-export" should be accessable via Macro/API, too.
I think that you should possibly put in a new bug report about being able to limit the repagination to a particular page number, so that the export of the first page can be generated quickly.
Bug 88775 suggests an "All pages" checkbox and bug 48015 suggests the same range options mentioned in the description.
