![]() ![]() 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? ![]()
