Update the XCF docs to any 2.10 changes
GIMP version: 2.10.12 Operating System: Arch Linux and all others Is the issue reproducible? : Always
The facts: at this time, Gimp 2.10 XCF files can be only loaded by Gimp (to be written by another application is not the subject here) Except Gimp 2.10, none application is able to display Gimp 2.10 XCF multi-layers thumbnails. Digikam, Gthumb, Nautilus, Thunar, Pcmanfm, Gwenview, Geeqie, etc, none of them can display XCF thumbnails
It has changed since 2.9 version. Before, other graphic applications could display <= 2.8 Gimp version XCF thumbnails. Why this changing behaviour? It's a big problem for users and others apps developers.
This issue doesn't come from others softwares developers incompetence. It comes from the fact that Gimp 2.10 code cannot be used inside other graphic softwares. I imagine they could, in an other world, do a kind of "reverse engineering" but that would be a strange thing in a Free Software / Open Source world.
Personally, I use Gimp and Digikam. As i explain above, since 2.9 Gimp version, I can't see XCF thumbnails in Digikam. I have to convert Gimp 2.10 XCF files to proprietary Adobe format, .psd, to see them. It may sound strange in the Linux world but, sadly, it's the reality....
Gimp is an extraordinary, irreplaceable software but, I regret to announce here that Gimp 2.10 XCF format looks like a closed format. On paper, the code is open but, in facts, it is unusable in other projects, just like a closed code. All open source file formats offer a library to handle the data inside. Why not Gimp ?
