CR2 THUMBNAILER HOW TO
CR2 THUMBNAILER WINDOWS

Mobile phones are moving rapidly from jpeg to heif and even cameras like any Canon R model shoots CR3 raw and HEIF as lossy compressed format. Exiv2 is supposed to be much faster and robust as far as I’ve heard.Īnother problem I forgot to mention with the current thumbnailer in gnome is that it’s not generating or getting thumbnails from the metadata at all for the HEIF, HEIC, AVIF and CR3 images. But in the foss world, all of the apps that deal with raw files have moved or are moving from LibRaw to Exiv2.

Windows (and probably MacOS) uses LibRaw for accessing (or generating, idk) it. Yes, every raw file has thumbnails at multiple sizes embedded in it.

CR2 THUMBNAILER HOW TO

With digital images being more and more a part of our daily lives, with most modern phones having the ability to shoot raw and high megapixel raw images, with the introduction of high quality and cheaply available mirrorless cameras in the past 5 years, with GIMP and Darktable being some of the two most downloaded apps on app stores across all linux distributions, I’d like to ask if there is something that Gnome can do about it? Perhaps develop a state of the art raw thumbnailer for Gnome? If anyone is interested and skillful in that area? I myself don’t know how to code that but it would be well worth it for GNOME and various distros that are using it.

When testing the raw thumbnail generation on MacOS and Windows it happens almost instantly. On a low end machines it’s not even worth having the thumbnailer, the time it takes to generate thumbnails is too long to be of any real use. You can basically stare at the screen and count the seconds between each thumbnail that can take from 2 up to 10 seconds per thumbnail. User basically has to wait for thumbnails to appear, and wait a long time. Depending on how many raw files are you seing in Nautilus, the thumbnail generation can last for over 30min (for a few hundreds of raw images, which is not a lot) on a very high end machine. After you add the miemetypes and thumbnails are finally being generated, we still have the issue with thumbnail generation being way way too slow. They would just see that no thumbnails being generated and leave Linux. I’d imagine for most ordinary users that would be the end of the road.

You have to edit /usr/share/thumbnailers/gdk-pixbuf-thumbnailer.thumbnailer and manually add miemetypes otherwise thumbnails won’t be generated. On Linux/GNOME however that is not the case.įirst of all, it doesn’t even come preconfigured to generate thumbnails for raw images on any distro. You can open thousands of raw images in the systems file manager and you can’t even percieve the time it took to generate thumbnails. On any other operating system, working with raw files and images is a brezze.
