Summary0002388: Add export into tif-files
Descriptionthats not possible at the moment by the image exporter.

As discussed on IRC, ringerc said:
"We should ideally be using libjpeg, libpng and libtiff directly (and stuff the other formats), and doing the export more efficiently than we currently do - an mmapped file, or similar, if possible.
QImage is *bad* for big images."
TagsNo tags attached.

Yep. It seems that QImage may be a real memory hog for big images. I haven't actually done any formal testing on this, but I've managed to swap my 2GB RAM desktop to death a couple of times exporting big pages as images from Scribus ;-)

It might be worth seeing if there's anything we can do to progressively render a page or render to an mmap()ped file. If it can work with QImage, all the better, but it might be better to support direct use of libjpeg, libpng, and libtiff were possible (more flexibility - eg CMYK TIFF export, alpha in PNG, etc).

Done thanks to qt4. The memory efficiency stuff is duplicate of 0001398
