  • Pixel-fitting - "Most icons and logos are stored in vector image files that specify perfect mathematical representations of their shapes. Unlike JPG and PNG images, vector graphic files don’t tell the computer how to display their contents in pixels that can be displayed on a screen; for a vector graphic to be displayed, the computer has to perform a translation from the mathematical vectors into something that can be displayed with pixels on the screen."

  • About those vector icons · Pushing Pixels - "Listing “one [SVG] icon, infinite sizes” as one of the advantages, it seems to be a great solution, but only for duotone, or more precisely purely black and white, icons. In addition, it completely fails to address the giant elephant in the room – what to do for complex icons that do not scale well to small sizes? Type engines have two major approaches to solve this problem – embedding bitmaps and font hinting."


  • - the set of mechanisms for creating visual images directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves, and polygons. These mechanisms may include vector display and printing hardware, vector data models and file formats, and software based on these data models (especially graphic design software, Computer-aided design, and Geographic information systems). Vector graphics are an alternative to raster graphics, each having advantages and disadvantages in general and in specific situations.




  • - an SVG optimizer/cleaner that reduces the size of scalable vector graphics by optimizing structure and removing unnecessary data written in Python.It can be used to create streamlined vector graphics suitable for web deployment, publishing/sharing or further processing.

  • Professor Cloud - converts SVG into an HTML5 Canvas JavaScript function. It will work with any host, and I hope it helps people to experiment with Canvas. Most vector art packages (Illustrator, Inkscape etc) can export as SVG.

  • canvas-svg - a set of related components that make canvas and SVG play together more. Notably, it allows you to save a canvas 2D context as SVG, and to have an SVG mirror of a canvas context.

Raster/ / bitmap

  • - In computer graphics and digital photography, a raster graphics represents a two-dimensional picture as a rectangular matrix or grid of square pixels, viewable via a computer display, paper, or other display medium. A raster is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. Raster images are stored in image files with varying dissemination, production, generation, and acquisition formats. The printing and prepress industries know raster graphics as contones (from continuous tones). In contrast, line art is usually implemented as vector graphics in digital systems. Transposing an image to covert raster organization (a relatively costly operation for packed formats with less than a byte per pixel); composing an additional raster line reflection (almost free), either before or afterwards, amounts to a 90° image rotation in one direction or the other. Many raster manipulations map directly onto the mathematical formalisms of linear algebra, where mathematical objects of matrix structure are of central concern.

  • - a very simple Bitmap parser. The goal here is to understand how an image file works behind the scenes. I chose the Bitmap format because it often does not contain compression, so it is an easy starting point.


  • - a public domain metadata standard which allows georeferencing information to be embedded within a TIFF file. The potential additional information includes map projection, coordinate systems, ellipsoids, datums, and everything else necessary to establish the exact spatial reference for the file. The GeoTIFF format is fully compliant with TIFF 6.0, so software incapable of reading and interpreting the specialized metadata will still be able to open a GeoTIFF format file.

An alternative to the "inlined" TIFF geospatial metadata is the *.tfw World File sidecar file format which may sit in the same folder as the regular TIFF file to provide a subset of the functionality of the standard GeoTIFF described here.

  • Cloud Optimized GeoTIFF - A Cloud Optimized GeoTIFF (COG) is a regular GeoTIFF file, aimed at being hosted on a HTTP file server, with an internal organization that enables more efficient workflows on the cloud. It does this by leveraging the ability of clients issuing ​HTTP GET range requests to ask for just the parts of a file they need.


  • - a plain text binary image format, for storing cursor and icon bitmaps used in the X GUI.[2] The XBM format is superseded by XPM, which first appeared for X11 in 1989.


  • - an image file format used by the X Window System, created in 1989 by Daniel Dardailler and Colas Nahaboo working at Bull Research Center at Sophia Antipolis, France, and later enhanced by Arnaud Le Hors. It is intended primarily for creating icon pixmaps, and supports transparent pixels. Derived from the earlier XBM syntax, it is a plain text file in the XPM2 format or of a C programming language syntax, which can be included in a C program file.


  • DICOM - the international standard for medical images and related information. It defines the formats for medical images that can be exchanged with the data and quality necessary for clinical use. DICOM® is implemented in almost every radiology, cardiology imaging, and radiotherapy device (X-ray, CT, MRI, ultrasound, etc.), and increasingly in devices in other medical domains such as ophthalmology and dentistry. With hundreds of thousands of medical imaging devices in use, DICOM® is one of the most widely deployed healthcare messaging Standards in the world. There are literally billions of DICOM® images currently in use for clinical care. Since its first publication in 1993, DICOM® has revolutionized the practice of radiology, allowing the replacement of X-ray film with a fully digital workflow. Much as the Internet has become the platform for new consumer information applications, DICOM® has enabled advanced medical imaging applications that have “changed the face of clinical medicine”. From the emergency department, to cardiac stress testing, to breast cancer detection, DICOM® is the standard that makes medical imaging work — for doctors and for patients. DICOM® is recognized by the International Organization for Standardization as the ISO 12052 standard.

  • - Digital Imaging and Communications in Medicine,, is the standard for the communication and management of medical imaging information and related data. DICOM is most commonly used for storing and transmitting medical images enabling the integration of medical imaging devices such as scanners, servers, workstations, printers, network hardware, and picture archiving and communication systems (PACS) from multiple manufacturers. It has been widely adopted by hospitals and is making inroads into smaller applications such as dentists' and doctors' offices. DICOM files can be exchanged between two entities that are capable of receiving image and patient data in DICOM format. The different devices come with DICOM Conformance Statements which state which DICOM classes they support. The standard includes a file format definition and a network communications protocol that uses TCP/IP to communicate between systems.


  • OpenEXR - provides the specification and reference implementation of the EXR file format, the professional-grade image storage format of the motion picture industry. The purpose of EXR format is to accurately and efficiently represent high-dynamic-range scene-linear image data and associated metadata, with strong support for multi-part, multi-channel use cases. OpenEXR is widely used in host application software where accuracy is critical, such as photorealistic rendering, texture access, image compositing, deep compositing, and DI. OpenEXR is a project of the Academy Software Foundation.

  • - a high-dynamic range, multi-channel raster file format, released as an open standard along with a set of software tools created by Industrial Light & Magic (ILM), under a free software license similar to the BSD license. It is notable for supporting multiple channels of potentially different pixel sizes, including 32-bit unsigned integer, 32-bit and 16-bit floating point values, as well as various compression techniques which include lossless and lossy compression algorithms. It also has arbitrary channels and encodes multiple points of view such as left- and right-camera images.

  • develops new JPEG features and maintains the Independent JPEG Group's (IJG) software.

"when your JPEG image is under 10K, it’s better to be saved as baseline JPEG (estimated 75% chance it will be smaller) for files over 10K the progressive JPEG will give you a better compression (in 94% of the cases)"

  • pngquant is a command-line utility and a library for converting 24/32-bit PNG images to paletted (8-bit) PNGs. The conversion reduces file sizes significantly (often as much as 70%) and preserves full alpha transparency. [7]




  • - a very fast C++ .PNG image reader/writer for 24/32bpp images. It's a single source file with no dependencies on any other library. fpng.cpp was written to see just how fast you can write .PNG's without sacrificing too much compression. The files written by fpng conform to the PNG standard, are readable using any PNG decoder, and load or validate successfully using libpng, wuffs, lodepng, stb_image, and pngcheck. PNG files written using fpng can also be read using fpng significantly faster than other PNG libraries, due to its explicit use of Length-Limited Prefix Codes and an optimized decoder that exploits the properties of these codes.


  • Richard Geldreich's Blog: Announcing CPNG, "Compatible Network Graphics", a backwards compatible fork of PNG - a 100% backwards compatible fork of the ~30 year old PNG image format, which is still thoroughly, and probably forever, stuck in the 1990's. I've been quietly designing, prototyping, and shipping CPNG's key features over the past couple years on github. Why continue messing with PNG at all? Because if you can figure out how to squeeze new features into PNG in a backwards compatible way, it's instantly compatible with all browsers, OS's, engines, etc. This is valuable.

  • - Abstract: Image quality measures are becoming increasingly important in the field of computer graphics. For example, there is currently a major focus on generating photorealistic images in real time by combining path tracing with denoising, for which such quality assessment is integral. We present ꟻLIP, which is a difference evaluator with a particular focus on the differences between rendered images and corresponding ground truths. Our algorithm produces a map that approximates the difference perceived by humans when alternating between two images. ꟻLIP is a combination of modified existing building blocks, and the net result is surprisingly powerful. We have compared our work against a wide range of existing image difference algorithms and we have visually inspected over a thousand image pairs that were either retrieved from image databases or generated in-house. We also present results of a user study which indicate that our method performs substantially better, on average, than the other algorithms.To facilitate the use of ꟻLIP, we provide source code in C++, CUDA, MATLAB, NumPy/SciPy, and PyTorch.

  • Freestyle - software for Non-Photorealistic Line Drawing rendering from 3D scenes. It is designed as a programmable interface to allow maximum control over the style of the final drawing: the user "programs" how the silhouettes and other feature lines from the 3D model should be turned into stylized strokes using a set of programmable operators dedicated to style description. This programmable approach, inspired by the shading languages available in photorealistic renderers such as Pixar's RenderMan, overcomes the limitations of integrated software with access to a limited number of parameters and permits the design of an infinite variety of rich and complex styles. The system currently focuses on pure line drawing as a first step. The style description language is Python augmented with our set of operators.




Neural Photo Editor


Deep Image Prior

  • Deep Image Prior - deep convolutional networks have become a popular tool for image generation and restoration. Generally, their excellent performance is imputed to their ability to learn realistic image priors from a large number of example images. In this paper, we show that, on the contrary, the structure of a generator network is sufficient to capture a great deal of low-level image statistics prior to any learning. In order to do so, we show that a randomly-initialized neural network can be used as a handcrafted prior with excellent results in standard inverse problems such as denoising, superresolution, and inpainting. Furthermore, the same prior can be used to invert deep neural representations to diagnose them, and to restore images based on flash-no flash input pairs. [43]




  • PixiVisor - a tool for experimenting with the transmission of video over audio. It consists of two parts: Transmitter and Receiver.

In Xfig, figures may be drawn using objects such as circles, boxes, lines, spline curves, text, etc. It is also possible to import images in formats such as GIF, JPEG, EPS, PostScript, etc. Those objects can be created, deleted, moved or modified. Attributes such as colors or line styles can be selected in various ways. For text, 35 fonts are available. Xfig saves figures in its native text-only "Fig" format. Xfig has a facility to print figures to a PostScript printer too. A convenient feature is the PSTEX or PDFTEX export format that allows a smooth integration of Xfig-generated images into LaTeX documents.


  • GrafX2 - a bitmap paint program inspired by the Amiga programs ​Deluxe Paint and Brilliance. Specialized in 256-color drawing, it includes a very large number of tools and effects that make it particularly suitable for pixel art, game graphics, and generally any detailed graphics painted with a mouse. The program is mostly developed on Haiku, Linux and Windows, but is also portable on many other platforms. [45]


  • rx - an extensible, modern and minimalist pixel editor, designed with great care and love for artists and hackers. It was conceived to have as little UI as possible, and instead focus on the work. rx To achieve this, rx takes inspiration from vi's modal nature and is built around a command system, unique to tools of its kind. [46]


  • Seashore - an open source image editor for Mac OS X's Cocoa framework. It features gradients, textures and anti-aliasing for both text and brush strokes. It supports multiple layers and alpha channel editing. It is based around the GIMP's technology and uses the same native file format. However, unlike the GIMP, Seashore aims to serve the basic image editing needs of most computer users, not to provide a replacement for professional image editing products. Also, unlike GIMP, Seashore has an all-new Cocoa UI that will fit right in on Mac OS X.


  • VPaint is an experimental vector graphics editor based on the Vector Animation Complex (VAC), a technology developed by a collaboration of researchers at Inria and the University of British Columbia, featured at SIGGRAPH 2015. It allows you to create resolution-independent illustrations and animations using innovative techniques. [47]


  • - Convert any image into a Voronoi diagram. The result is a set of polygons of solid color, which can be used as a basis for a mosaic or other artistic rendering.


  • - A flowchart/node-based image processing GUI aimed at making chaining image processing tasks (especially upscaling done by neural networks) easy, intuitive, and customizable. No existing upscaling GUI gives you the level of customization of your image processing workflow that chaiNNer does. Not only do you have full control over your processing pipeline, you can do incredibly complex tasks just by connecting a few nodes together. chaiNNer is also cross-platform, meaning you can run it on Windows, MacOS, and Linux.

  • DALi - a dynamic animation library, a 2D and 3D scene graph that abstracts the rendering of the nodes through a simple API. It can be used to create 2D and 3D applications, providing support for resource loading, touch events, key events, animating the nodes and a whole array of functionality to make it easy for the user to produce effects, applications and user interfaces. DALi is developed with user input responsiveness, smooth updates with good FPS and low memory requirements in mind. A Toolkit is provided to make using DALi even easier along with a framework that facilitates the creating of your own controls. DALi is Open Source, constantly maintained and extended.DALi provides 2 apis, the native C++ and NUI which is based on C#.

  • - a new open-source 2D animation software for Linux. You can use enve to create vector animations, raster animations, and even use sound and video files. Enve was created with flexibility and expandability in mind.

  • Shutter is a feature-rich screenshot program. You can take a screenshot of a specific area, window, your whole screen, or even of a website – apply different effects to it, draw on it to highlight points, and then upload to an image hosting site, all within one window.

  • ScreenCloud - Take a screenshot using one of the 3 hotkeys or simply click the ScreenCloud tray icon.




  • Fawkes - takes your personal images and makes tiny, pixel-level changes that are invisible to the human eye, in a process we call image cloaking. You can then use these "cloaked" photos as you normally would, sharing them on social media, sending them to friends, printing them or displaying them on digital devices, the same way you would any other photo. The difference, however, is that if and when someone tries to use these photos to build a facial recognition model, "cloaked" images will teach the model an highly distorted version of what makes you look like you. The cloak effect is not easily detectable by humans or machines and will not cause errors in model training. However, when someone tries to identify you by presenting an unaltered, "uncloaked" image of you (e.g. a photo taken in public) to the model, the model will fail to recognize you. Fawkes


  • - A (thoroughly) parallelized experimental Rust vector-graphics renderer with both a software (CPU) and hardware (GPU) back-end having the following goals, in this order: Portability; supporting Fuchsia, Linux, macOS, Windows, Android & iOS. Performance; making use of compute-focused pipeline that is highly parallelized both at the instruction-level and the thread-level. Simplicity; implementing an easy-to-understand 4-stage pipeline. Size; minimizing the number of dependencies and focusing on vector-graphics only.

  • OpenBR - A communal biometrics framework supporting the development of open algorithms and reproducible evaluations.

  • ReCode Project - a community-driven effort to preserve computer art by translating it into a modern programming language (Processing). Every translated work will be available to the public to learn from, share, and build on.

  • - a project that estimates the psychovisual similarity of two images. It gives a score for the images that is reliable in the domain of barely noticeable differences. Butteraugli not only gives a scalar score, but also a spatial map of the level of differences. [54]

  • Enfuse - Wiki - command-line program used to merge different exposures of the same scene to produce an image that looks very much like a tonemapped image (without the halos) but requires no creation of an HDR image. Therefore it is much simpler to use and allows the creation of very large multiple exposure panoramas.

  • - I worked for a long time in financial services, and I can tell you that one thing I got sick of hearing was "how do I convert animated GIFs into Excel files". If you're here wondering why nobody has yet exploited this gap in a very lucrative market, wonder no longer. Help is at hand.

Machine learning


  • - web server software which specializes in delivering (and often modifying) images. However, not all image servers support HTTP or can be used on web sites. While traditional web servers generally supply clients with static copies of image files, image servers usually perform additional image processing before serving the file. These functions may include frame/format selection, resizing, cropping, alpha blending, compositing source images, rotating, color adjustment, and filtering. A major use of image servers is to support browser-based pan-and-zoom viewers. port/1188

  • IIIF - International Image Interoperability Framework, a set of open standards for delivering high-quality, attributed digital objects online at scale. It’s also an international community developing and implementing the IIIF APIs. IIIF is backed by a consortium of leading cultural institutions.

  • IIPImage - an advanced high-performance feature-rich image server system for web-based streamed viewing and zooming of ultra high-resolution images. It is designed to be fast and bandwidth-efficient with low processor and memory requirements. The system can comfortably handle gigapixel size images as well as advanced image features such as 8, 16 and 32 bits per channel, CIELAB colorimetric images and scientific imagery such as multispectral images and digital elevation maps. Streaming is tile-based, making it possible to view, navigate and zoom in real-time around gigapixel size images that would be impossible to download and manipulate on the local machine. It also makes the system very scalable as the number of image tile downloads will remain the same regardless of the size of the source image. Source images can be in either TIFF or JPEG2000 format. Whole images or regions within images can also be rapidly and dynamically resized and exported by the server from a single source image without the need to store multiple files in various sizes.

  • Cantaloupe Image Server :: Home - an open-source dynamic image server for on-demand generation of derivatives of high-resolution source images. With available operations including cropping, scaling, and rotation, it can support deep-zooming image viewers, as well as on-the-fly thumbnail generation. Compliance with the IIIF Image API enables it to work with a growing number of client applications.
