I just reworked an old document written in Writer five years' ago. My
intention was to replace all the images with new ones.
There are 69 png images in the doc and all are black and white line
drawings saved, at the time, in RGBA format with transparency. The
replacement images are pngs saved in grayscale without transparency.
Without exception, each replacement image is smaller than the
original. The original images totalled 5.49 MiB and the replacements
3.89 Mib.
My replacement procedure was to delete an image and then insert its
replacement, check its anchor, wrap alignment and size to be
identical to the original, and then pass on to the next image ... etc.
The old document was 4.7 MiB with its original images and I expected
the new document to be smaller. Instead, it is now 8.1 MiB. It has
gained 3.4 MiB which is close to the overall size of the new images.
Does this mean that the odt document retains all the old history
including the original images? I'd like to get back to something
smaller than the original 4.7 MiB so would welcome ideas for pruning
it back without rewriting from scratch.

Sorry. Stupid post. I forgot to check the original document. All the
original images were linked in and not inserted.

That solves that issue. I have been reworking my documents replacing the
PNGs of line drawings with PDFs created as vector art so that the output
PDFs remain crisp and sharp when zoomed for fine detail. It is
interesting thinking back on the evolution of the images. Originally
EPS, then PNG and now PDF.
