digiKam is a KDE photo collection manager. It provides streamlined importing and organizing/classifying them into albums or chronologies. Besides allowing custom directory schemes for storage, it also permits plain tagging, indexing and rating. Through KIPI it integrates with other KDE photo management software; but also provides a Light Table tool to pick highest quality shots from a series, or retouch them. A built-in image editor can apply colorization and lightning correction effects.
Crosti helps in creating custom cross-stitching schemes from image files / photographs. It supports all common raster and vector images, permits various colorizations and adaptions, resizing and rotating templates, adding lines or circles, and obviously printing them out.
Gwyddion is a modular SPM (Scanning Probe Microsope) data visualization and analysis tool. It can be used for all most frequently used data processing operations including: leveling, false color plotting, shading, filtering, denoising, data editing, integral transforms, grain analysis, profile extraction, fractal analysis, and many more. The program is primarily focused on SPM data analysis (e.g. data obtained from AFM, STM, NSOM, and similar microscopes). However, it can also be used for analyz
libpng is the PNG image format reference implementation. Portable Network Graphics are the most widely used raster image format, patent-free, based on lossless data compression, support indexed/paletted, grayscale, and 24 or 32 bit truecolor images with transparency. It's also an highly extensible container format, with built-in color profiles and representation information, textual meta data, filters, progressive interlacing, and permits animations in the derived APNG or MNG formats.
Simple to use paint program like Paintbrush for Mac or classic MS Paint, but for Linux.
Pixelitor is a Java/cross-platform image editor. It provides image filters, drawing tools, layered editing, bleding modes, multiple undo steps, etc. Its main attraction are the more than 80 unique image filters and color adjustment tools. Besides supporting standard graphic files, it defaults to saving in its custom PXC format (a gzipped Java object serialization for retaining layer data).
TubePress provides a modern photo and video gallery PHP script. It can index and display thumbnails, photo meta data, categories, Youtube/Vimeo videos, favourites. TubePress displays them either embedded, in popups or modal overlays.
This program allows you to view BPG Images in Windows, Linux and macOS. Features: * Large images are autoscaled to fit screen area * Basic support for animated images (zooming, rotating and exporting for animated images are not supported) * Zoom In/Out * Full screen mode * Support mouse dragging of the zoomed image * Cyclic view of all images in the same directory * Saving a copy of the opened file as a PNG file * Saving a copy of the opened file * Deleting the opened files * Rotating the view (
shufti is a lightweight, PyQt-based image viewer that non-destructively saves and restores the zoom level, rotation, window size, desktop location and viewing area on a per-image/file location basis.
An alternative to Windows' built in Snipping Tool with auto Imgur Upload or Image to Clipboard Copy for even faster Image sharing.
Pure Java cross-platform image processing framework that provides features for image and video frame processing, multi-threading image processing, GUI integration, extensibility via plug-ins, unit text automation among other things.
FIM is a lightweight universal image viewer, mostly for Linux. It is highly customizable and scriptable, and for users who are comfortable with software like the VIM text editor or the Mutt mail user agent. You can control it using the keyboard. FIM can open many file formats (even using converters) and it can display pictures graphically, with the Linux framebuffer or under X/Xorg, or in a terminal as ASCII Art renderings.
wxSVG is C++ library to for Scalable Vector Graphic (SVG) files. It can create, manipulate and render them using the wxWidgets toolkit.
Pinta is a graphics drawing/editing program modeled after Paint.NET. It strives to be simple yet feature-rich, and runs cross-platform. Drawing tools include freehand, lines, rectangles, ellipses, and more. It allows unlimited layering, undo and redo history, over 35 image effects, and supports floating or MDI workspace layout.
BPGconv can convert multiple JPEG or PNG files into BPG files at once. The conversion processes run parallel to each other, so they can be completed in a shorter time. You can also visually confirm the change in file size from before and after the conversion. The application screen is made up of a single screen. It is designed so you can complete all operations without the need to go back and forth between multiple windows. You can switch between encoding (JPEG/PNG to BPG) and decoding (BPG to J
BPG (Better Portable Graphics) is a new image format. Its purpose is to replace the JPEG image format when quality or file size is an issue. Using BPGviwer you can view any BPG file.BPG is a lossy and lossless picture compression format based on High Efficiency Video Coding(HEVC))
DiffImg computes pixel discrepancies between two image files and displays them as color mask or as yellow/red overlay. It also provides a dual panel display, can compute the mean error, RMS and min/max values, shows an error histogram, or display a slideshow for image directories. This allows for compression level comparisons, or optimizing raytracing parameters.
A simple cross platform GIF animator, written in Java.
KPhotoAlbum lets you index, search, group and view images by keywords, date, locations and persons. It provides a quick and elegant way to lookup groups of images when you have thousands of pictures on your hard disk. The information associated with each photo is stored in an XML file. Together with its keywords, KPhotoAlbum stores each picture's MD5 sum, so it will recognize them even if you move them to another directory. KPhotoAlbum can also create HTML galleries with the images you select
