--- Comment #5 from Vasily Melenchuk (CIB) <vasily.melenchuk at cib.de> ---
Current implementation (see
https://opengrok.libreoffice.org/xref/core/sdext/source/minimizer/optimizerdialogcontrols.cxx#791-806)
is making very rough calculation based only on desired JPG compression and
resolution. This approach gives very rough estimation even for JPEG images, but
here are many factors not taken into account, like removing hidden slides,
cropping images, etc.

Theoretically, I see no limitations to provide more precise filesize
estimation.
