glViewImage is a user-friendly and open source image viewer that enables users to zoom in, zoom out, and move images. It is free software that provides simple functionality for viewing images.
One of the things that sets glViewImage apart from other image viewers on the market is its ability to handle a variety of image formats. From PNG to BMP to PPM, this software has you covered. It even supports RGBE, a format that allows for a high dynamic range of colors. While there are a few formats that are only partially supported (such as PCX and IPL), these are minor limitations that don't detract from the overall functionality of the program.
One unique feature of glViewImage is its ability to load external programs in order to support additional file formats. While this isn't necessarily the smoothest process, it does mean that users are able to access a wider range of images with minimal effort. The only requirement for this setup is that the convert program from the ImageMagick package is available on your $PATH.
Of course, like any software, glViewImage does come with a few requirements. Users will need access to X11, libpng, OpenAL, GTK and GtkGLExt, and vorbisfile in order to run the program smoothly. But for those who meet these requirements, glViewImage is a great choice for a simple, easy-to-use image viewer.
