It is an open source and cross platform software for Windows, Linux and macOS. The program opens up to a blank screen, which is not unlike qimgv. Right-click to access the qView menu, click open to select an image, and the program loads the picture.
Don't like that method? Use the context menu to navigate to the Options > Window tab, and enable the menu bar. This tab also lets you change the background color of the interface, set the title bar style (Basic, Minimal, Verbose), and the automatic resizing behavior of the window.
You can drag an image to position it anywhere on the screen. It's useful when you're viewing a wide-angle picture or a panorama. To Zoom in or out, use the mouse wheel.
Double-clicking on a picture switches to full-screen view. A second-double click takes you to the windowed mode. Once an image has been loaded in qView, you can jump between other pictures that are in the same folder using the arrow keys. The application has several keyboard shortcuts that you can view from the Shortcuts tab in the Options. And yes, the shortcuts can be modified.
qView supports the following image formats: JPG, BMP, GIF, PNG, CUR, ICNS, ICO, JP2, JPEG, JPE, MNG, PBM, PGM, PPM, SVG, SVGZ, TIF, TIFF, WBMP, WEBP, XBM and XPM. Yes, that includes animated GIFs. The program also supports web images, i.e., you can paste a picture's URL to view it in the qView directly. The context menu can be used to access recently viewed images, open an image's folder in Explorer.
The "show file info" option lists the picture's name, format, location, size, resolution with megapixel count, and aspect ratio. The View menu has options to reset the zoom, view an image in its original size, full screen, rotate, flip or mirror the picture. Watch a slideshow of an image folder from the tools menu in qView. By default, it loads the next image after 5 seconds. You can modify this setting from the program's options. The application allows you to set the sorting order (Name, Last Modified, size, type).
The program uses bilinear filtering and image scaling, and these are pre-enabled, but you can toggle them if required. The default zoom level, and behavior for zoom and window resize are also customizable to some extent.
qView is written in QT. The application is available in 32-bit and 64-bit versions. Portable archives of qView can be found at the download page. You may use the DEB file at the download page, to install the Linux version. The Linux and Windows versions are identical.
The program doesn't use a lot of resources when you use it normally. I did notice a memory spike viewing a slideshow of high resolution photos, it jumped from 75MB to 150MB, but that may have been due to the fact that the picture was very large in size. Otherwise, it stayed in the 70s for the most part.
Thanks to gHacks reader Hashama, for mentioning qView in the comments section of the ImageGlass article.
