Open Source Image Viewers

GraphicsMagick provides a set of commandline tools and programming APIs for manipulating, editing, and converting raster and vector images. It is derived from ImageMagick, with the objective of providing better stability and performance than ImageMagick while retaining the original MIT/X11 license.

JPEGView is a lean, fast and highly configurable viewer/editor for JPEG, BMP, PNG, WEBP, TGA, GIF and TIFF images with a minimal GUI. Basic on-the-fly image processing is provided - allowing adjusting typical parameters as sharpness, color balance, rotation, perspective, contrast and local under-/overexposure.

This is a lightweight image viewer with basic image processing. A thumbnail bar is shown at the bottom of the window with all the images in the folder. The name of the current image and the toolbar are shown at the top of the window. Use the toolbar to access basic commands like: image slideshow, adjust zoom, rotate, delete, crop or resize the image, sort the list or access the program settings. Move the mouse near the left or right side of the window to show the arrows and select the next or previous image. Move the mouse over the buttons to see a short description or over the thumbnails to see more information. By default, the viewer starts in full screen mode but it can be switched to windowed mode by pressing F11. Also, you can press Enter to hide or show the toolbars, Space to start the slideshow or Escape to exit the program. To use this program as the default viewer for any image file, right click on the file and use the "Open with" option in the context menu.

AiGfxLab is a powerful open source image processing application for Windows. The plugin architecture permits both general-purpose and specialized processing, with an emphasis on intuitive GUI, numerical accuracy, maximal extensibility and customization.

Image tagging (without using metadata) software written in Java (1.6). All image processing is taken care of by ImageMagick through JMagick. See wiki for main features/issues.

An IDE for people interested in Machine Vision/Image Processing. Written in Java, using JAI. It allows users to view image data and also provides a drag and drop environment that users can create/execute graphs of JAI operators.

The JPedal JBIG2 Image Decoder is a 100% pure Java image decoder for the JBIG2 file format. The decoder takes the JBIG2 image processing technology developed for the JPedal PDF renderer in 2007 and makes it available as a generic library for more general usage. The JDeli Image Library https://www.idrsolutions.com/jdeli contains a much enhanced and faster version and also provides a complete ImageIO replacement (see https://www.idrsolutions.com/jdeli/imageio-replacement) for Tiff, JPEG, JPEG2000, Png as well as lots of other image formats including Dicom, WMF, PSD, SGI and WebP.

JaToo Imager is a Java Open Source application created to view and alter images. Batch processing is also provided.

jIR is an open source project focused on building an open platform for image processing tasks. It is composed of individual algorithms whose task is to extract or compare information in a data set of images.

PGMania is a universal package for processing deep space images. The program provides wide and unique functionality, a powerful and flexible tool with a clear and user-friendly interface. The program performs all image processing cycles for astrophotography, including filtering, cleaning, aligning, image calibrating, stacking, post-processing, format conversion, cropping, rotations, many special operations and much more. PGMania is environmentally friendly - it does not clutter your photos with something that was never there. You get full control over all processing processes and the most clean and accurate result at all cycles. The program has a clear and user-friendly interface and detailed help for all stages of processing.

wxyzv is very small image viewer (with minimal image processing functions) that works under X Window System or SVGAlib. It needs no external image processing libraries or GUI libraries. It has no GUI, it is completely keyboard-driven.
