Size estimate for save dialogue

Post by golemus »

Hi. I am not sure if I put this already somewhere else but didn't find it.

Some programs (Affinity, Photoshop?, Image Toolbox, etc..) tell in save dialouge/settings the estimated size of file to be saved. It would be very handy feature for xnmp as you wouldn't have to save multiple files and then start to study in file explorer which one became the size that you want (in the scenario where size is of high importance. Below is illustration how it could look in save dialogue and where it might be easy to put it.

As there are many file formats so it might be challenging to implement it for all of them but it would be cool for most important ones, which are (IMO):

JPG, JXL, AVIF, WEBP,,,, PNG, HEIC, TIF, PDF?, SVG?

The size should update every time you modify saving settings (e.g. change quality parameter, pull quality slider, 4:2:0 to 4:4:4, progressive vs. non progressive encoding, etc...etc...

Hmm... I had almost forgotten that it exists. You are right it seems to have this feature. I will study it.

BUT AVIF is missing from export dialogue. Is this intended behaviour or bug, Pierre? All others are there that are chosen in Settings - Formats.

Settings > Formats has nothing to do with Export dialog

Add tab AVIF to Export window
