NOMACS UBUNTU MANUAL
I’d advise going through the manual for more details about the keyboard shortcuts in the program. This can be useful if you want a background with a frosted glass look.įeh supports common image formats such as JPG, PNG, BMP, GIF (non animated), etc. Hold the Control key and click with the mouse button and drag left to blur the photo or right to sharpen it. The only other editing options that Feh supports are the blur and sharpen tools. It will display the properties of the picture in a similar menu.įeh has a few options that you can enable including auto-zoom, freeze window size or fullscreen. The application also has a built-in EXIF viewer that you can access from the Image Info menu. Feh supports some viewing options such as the ability to sort the list by the name of the file or directory, last modified, or even set it to random view. You can rotate the picture and save it or set the image as your wallpaper. Feh is not an image editor but a viewer application don't expect too many options. Right-click on an image to access the context menu. The only exception is the multiwindow mode which uses feh -w as -m is already mapped to Montage. For the other modes, use the command feh followed by a space and the first letter of the mode, e.g., feh -m. I mentioned how you can open the slideshow and thumbnail.
List mode displays the properties of the images in the folder in this order: Format, Width, Height, Pixels, Size, Alpha and Filename. Multi window opens each image in its own window. Index mode displays the thumbnail and some of the image’s properties. Montage mode displays the images in a sequence. There are 6 viewing modes that the program supports: Slideshow (default), Montage, Index, Thumbnail, Multiwindow and List. For example, use feh -t to view the folder's gallery in thumbnail view and click on any thumbnail to view the larger version. Like most CLI apps, Feh has a ton of keyboard shortcuts for a nearly mouse-free usage. If you just want to open a single image you may type "feh filename.extension" instead to do so. The Slideshow mode of the viewer opens by default which means that you can view all images of the folder by using the right and left arrow keys, by left-clicking with the mouse, or using the scroll wheel. You can also right-click on images in the Files app (or other file managers) and select open with Feh. The image viewer should open and display the first image of that folder. So, how do you use Feh? There are 2 ways to do so: open a terminal in a folder that contains images, type "feh" and hit enter.
