“Overview
“Gwenview supports practically any image format handled by Qt,
like PNG, JPG, BMP, XPM, TGA or PNM. These are not all though, and
even the SVG (scalable vector graphics) format is supported.“Basically, Gwenview has two modes: browser view and image view
(which can also be viewed in fullscreen mode). The browser mode
displays previews of images in the current directory as thumbnails
which can be resized, while in view mode a single image is
displayed and it occupies most of the window space. The left
sidebar in view mode can be shown or hidden using F11 and includes
three tabs:– Folders, which is the file browser, displaying directories in
tree view mode
– Information, which shows image info, allows to set tags and
ratings
– Operations, which can show the KDE file properties window, or
actions like copy to/move to and delete current image”
