Partly, but not entirely. That's part of it, as it doubles or quadruples
the in-memory size of the decompressed image. However, Scribus also load
sall images into RAM, filters them into another buffer, and then writes
that out, so you'll end up with more than just the source image in RAM.
Suddenly 2GB of RAM doesn't look like so much anymore ;-)
The goal is to progressively read, filter, and write images to the PDF
so that the whole image need not be kept in RAM at once (let alone two
or three decompressed copies of it as now!). And, of course, not to use

Yes, as above.

There was some progress with progressive image reading in 1.3.4.
