GIT Repository (containing the source code of nomacs and all dependencies).If there is no package available for your favorite distribution, you can download the sources and compile nomacs according to the compile instructions.update your FreeBSD repository and change directory to /usr/ports/graphics/nomacs (if your repository directory is the default, otherwise change to the particular directory).repositories (Tumbleweed, Factory, 12.1, 11.4).nomacs is officially available on Arch Linux, simply install it with:.nomacs is included in the official repositories.Install the heif plugin to load heif images.translations can be added with sudo apt-get install nomacs-l10n.Just install it using your favorite package manager. nomacs is available in the “universe” repository of Ubuntu.We recommend installing nomacs from there if you want to have the latest version. © Markus Diem, Stefan Fiel, and Florian Kleber, 2011 – 2020 Windows (7/8/10) I should add that the zoom tool of the web site works well with Firefox for me in a computer with 4 GB RAM, I could reach a zoom level corresponding to full resolution of the 1.7 GB Tiff file and I could scroll horizontally and vertically to see the whole picture.Nomacs – Image Lounge is licensed under the GNU General Public License v3 This is a great picture well worth zooming into with the tools, that you have available. Please notice that I have measured the total usage of RAM (including the operating system). With 6 GiB RAM, you should select a light-weight viewer, and with 4 GiB probably be prepared to wait for some swapping. It should work with Ubuntu and 8 GiB RAM to view this picture with several viewers, and the editor gimp works really well for me. ristretto - does not work (silently, shows a thumbnail, but no picture).Gpicview - works but slower (failed to show full resolution directly, but works when gradually zooming in to full resolution, total RAM usage when showing and zooming 3016 MiB RAM, but 4219 MiB RAM during loading.įeh - does not work 'No ImLib2 loader for that file format' Shotwell - works also at full resolution (without delay), 7920 MiB RAM (after some horizontal and vertical scrolling at full resolution) It works well both with 16 GiB RAM and 8 GiB RAM. Gimp - works best for me also at full resolution (without delay), 6143 MiB RAM. The total RAM usage including operating system is measured with free -m. I tested with gimp also in a Dell Latitude E7240 with 8 GiB RAM and 18.04.1 LTS persistent live with Xorg. I tested to view the 1.7 GiB Tiff file in a Dell Precision M4800 with 16 GiB RAM and Ubuntu 18.04.1 LTS with Wayland. OUTPUT_FILE=$_tile_$TILE_NUMBER"_thumb.png"Ĭonvert -resize 100x100 $TILE_NAME $THUMBNAIL tile_image.sh originalImage tilesX tilesY, where tilesX is the number of tiles horizontally and tilesY is the number of tiles vertically. Maybe a bit off topic, but here's a quick&dirty bash script that tiles an image and creates an html page that displays an overview where you can click on a tile to open it in full resolution. To split the image into 5x3 parts and produce one file per part, use the following command: convert -crop inputfile.tif outputfile%0d.tifįor more information about convert, see man convert or take a look at the documentation. 41KP.Īdditionally, you need to increase the maximum disk space: In your case, the image has 40000x12788 pixels, so you only need to change the width to something greater than 40KP, e.g. You need to adjust the maximum size in pixels, which are defined in the following lines: You need to increase the default limits which are defined in /etc/ImageMagick-6/policy.xml (the number 6 may change in future versions). In general, if the image is too big to fit into RAM, you can split it using convert which is part of the imagemagick package. What options do I have if the image is way too big for RAM? Your best bet is trying GwenView (the default image viewer in Kubuntu, but can be installed in stock Ubuntu as well). GwenView went up to 3.8GB while loading and dropped to 2GB afterwards. The RAM usage gradually increased when editing the image. Gimp went up to 5GB and stayed there when viewing the image and zooming in. Shotwell took up to 5GB of RAM while opening the file and then dropped to 2GB. I did some (non-scientific) experiments and noticed differences between applications in three phases: when loading the image, after loading the image, when zooming in. Furthermore, depending on the application, there may be buffers that also need RAM. And that's where RAM and CPU come into play. When an application wants to display it, it needs to uncompress the image first. Why can't I open the image in any viewer?
