kenyee Posted July 3, 2017 Share Posted July 3, 2017 Tried using Affinity Photo for some retouch and found the initial file size w/ just two layers is 200MB :-O When I did a search for this, I found out this is a known problem since 2015 (or at least people have posted about it then)...was hoping it was fixed w/ the latest version which I have purchased because I like a lot of what you're doing. A similar image saved w/ gimp is only 36MB (bzip2'd which it automatically does if you save it to the gmp.bz2 extension). You folks should look into doing something like this. A finished edit w/ about 6 layers in Gimp is only about 80MB for me (though more destructive). Or when saving, save layers as diffs... Would make a nice program much better and more usable for me...as it is, I''m going to drop stuff into Affinity Photo as needed for using some of its tools, but will continue w/ Gimp until this file format size issue is solved...

rubs Posted July 4, 2017 Share Posted July 4, 2017 Also, using Save As sometimes reduces the file size because it discards unused data from the database, but all images are saved uncompressed nonetheless. It would be nice to have at least an option to compress the images as PNGs like most applications. This happens with Affinity Designer as well, since the file format is the same.

Staff Ben Posted July 4, 2017 Staff Share Posted July 4, 2017 The data in Affinity files is already lib compressed. We compress the different sections differently to give a balance between size and performance. We also will only use lossless compression for Affinity files. They are an editable document format, not an end storage format, so using lossy compression would be unacceptable. File sizes are comparable to the increase you see with PSD files, though we do store extra data to allow our files to be opened more quickly.

(Lossy is obviously out of question.) Quote Link to comment Share on other sites More sharing options...
