pViewer: Another Minimalist Image Viewer
pViewer (Version: 1.6) is a minimalist open source image viewer. It has no menu and little distraction.
pViewer’s options are available via right click and there are keyboard shortcuts for its features. These features are Send To Dropbox Public folder, rename, slideshow, rotate, flip, resize and read exif data. It supports effects such as invert, grayscale, sharpen, blur, brightness, contrast, tint, black border, white border and red eye correction. Additionally there is support for .zip, .rar, .cbz, .cbr archives with Manga and Comic mode displaying two images side by side.
The batch operations – resize, rotate, convert, rename, grayscale, invert white or back border – work on all images in the current directory and sometimes even without any additional prompts. For example Add White Border just goes to work and creates a subfolder containing the output.
The program settings has options for drawing and text color and fonts. These are not accessible via the right and looking at the keyboard shortcuts one sees the following
Crop: Ctrl+Click to make a selection, release the mouse button while still pressing Ctrl. Writing on the image: press Shift+Click on the picture to add text, write what you want, move it wherever you want with the mouse, press Ctrl+Enter.
Drawing a rectangle: Alt+Click and drag to draw, then you can save the edited image. Filling the rectangle: After drawing a rectangle you can fill it with the same color by pressing TAB
It is less than 1MB unzipped, doesn’t require installation and should run on Windows XP and newer.
Thanks to commenter andy for pointing out that it requires the .NET framework 4.0
