Images
Formats
- 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."
- Photography Stack Exchange: terminology - What does "frequency" mean in an image?
Vector
- https://en.wikipedia.org/wiki/Vector_graphics - 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.

Bitmap
- https://github.com/StanleySathler/bitmap-parser - 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.
TIFF
GeoTIFF
- https://en.wikipedia.org/wiki/GeoTIFF - 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.
XBM
- https://en.wikipedia.org/wiki/X_BitMap - 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.

- https://github.com/richgel999/fpng - 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.

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.

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. [41]

nomacs
- nomacs - a free, open source image viewer, which supports multiple platforms. You can use it for viewing all common image formats including RAW and psd images. nomacs features semi-transparent widgets that display additional information such as thumbnails, metadata or histogram. It is able to browse images in zip or MS Office files which can be extracted to a directory. Metadata stored with the image can be displayed and you can add notes to images. A thumbnail preview of the current folder is included as well as a file explorer panel which allows switching between folders. Within a directory you can apply a file filter, so that only images are displayed whose filenames have a certain string or match a regular expression. Activating the cache allows for instantly switching between images. nomacs includes image manipulation methods for adjusting brightness, contrast, saturation, hue, gamma, exposure. It has a pseudo color function which allows creating false color images. A unique feature of nomacs is the synchronization of multiple instances. With this feature you can easily compare images by zooming and/or panning at the exactly same position or even by overlaying them with different opacity.

CinePaint
- CinePaint - an open source computer program for painting and retouching bitmap frames of films. It is a fork of version 1.0.4 of the GNU Image Manipulation Program (GIMP). It enjoyed some success as one of the earliest open source tools developed for feature motion picture visual effects and animation work. The main reason for this adoption over mainline gimp was its support for high bit depths (greater than 8-bits per channel) which can be required for film work.[citation needed] The mainline GIMP project later added high bit depths in GIMP 2.9.2, released November 2015.

- https://github.com/3Dickulus/FragM - derived from Mikael Hvidtfeldt Christensen's Fragmentarium representing a compilation of features and fixes contributed by many users at FractalForums.com over 3-4 years.
XFig
- XFig - a free and open-source vector graphics editor which runs under the X Window System on most UNIX-compatible platforms. 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
- 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. [43]

Seashore
- 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

Xournal
- Xournal - an application for notetaking, sketching, keeping a journal using a stylus. It is free software (GNU GPL) and runs on Linux (recent distributions) and other GTK+/Gnome platforms. It is similar to Microsoft Windows Journal or to other alternatives such as Jarnal, Gournal, and NoteLab.
Jarnal
- Jarnal - an open-source application for notetaking, sketching, keeping a journal, making a presentation, annotating a document - including pdf - or collaborating using a stylus, mouse or keyboard. It is similar to Microsoft Windows Journal and to the earlier Mimeo whiteboarding and Palm notepad applications. There is also a commercial knockoff of Jarnal called PDF Annotator - for $50 you can enjoy a subset of the capabilities that Jarnal provides for free.
Gournal
- Gournal - note-taking application written for usage on Tablet-PCs (such as the Toshiba M200). It’s designed for usage with a stylus, not a mouse or keyboard. It does not have handwriting recognition but can be used in co-ordination with xstroke to accept text. Gournal is written in perl using gtk2-perl so you will need gtk2-perl along with the gladexml and gnomecanvas modules of gtk2-perl. The pages are saved as gzipped SVG files (not totally standard yet but working on it)
NoteLab
- NoteLab - brings the power of digital note taking to Linux, Windows, Mac OS X, and Solaris. Using NoteLab is just like writing with a pen on real paper. However with NoteLab, the pen and paper are electronic, you never run out of ink, and you have all the paper you'll ever need. NoteLab is free software licensed under the GNU GPL. Like Linux and Firefox, NoteLab and its full source code are available at no cost for anyone to view, analyze, scrutinze, and improve. NoteLab saves your notes in the industry standard SVG (Scalable Vector Graphic) format. Thus any program that can understand this open, next-generation graphic format can be used to view NoteLab files. NoteLab can also print your notes or export them to a number of image types including PNG and JPEG. NoteLab allows the user to select en tire words, stretch them, move them, change their color, change their line width, delete them, and bring them back. Simply speaking, NoteLab understands a stroke as a complex shape. It doesn't just look at the page as a collection of ink on a page, but instead as a collection of words in a dynamic environment.
