It can be used as a simple paint program, an expert quality photo retouching program, an online batch ... [More] processing system, a mass production image renderer, an image format converter, etc. GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything.

It supports almost all PNG features, is extensible, and has been extensively tested for over 17 years. libpng is available as ANSI C source code and requires zlib 1.0.4 or later (1.2.3 or 1.1.4 recommended due to potential security vulnerabilities in ... [More] earlier versions). In addition to the main library sources, libpng includes the rpng, rpng2 and wpng demo programs, the pngminus demo program, a subset of Willem van Schaik's PngSuite test images, and Willem's VisualPng demo program.

grafx2

Compare

  Analyzed almost 4 years ago

GrafX2 is a bitmap paint program that allows you to draw in more than 60 video resolutions including most of the standard Amiga resolutions : 320x200, 320x256, 320x512, 640x256, 640x512, etc. It was written to run under DOS, but the code you'll find here was modified to use SDL and modern operating ... [More] systems. This program is dedicated to everybody who knows what a single pixel is. Its layout is not very different from the famous Deluxe Paint or Brilliance, so it will be quite easy to handle it if you know at least one of these programs. If you aren't used to the art of drawing with up to 256 colors, it will be a little more difficult for you, but you should give it a try (or more, because most of the power of this program won't show up on the first try).

  Analyzed 3 days ago

GraphicsMagick is the swiss army knife of image processing. It provides a robust collection of tools and libraries which support reading, writing, and manipulating an image in over 88 major formats including important formats like DPX, GIF, JPEG, JPEG-2000, PNG, PDF, SVG, and TIFF. GraphicsMagick ... [More] supports huge images on systems that support large files, and has been tested with gigapixel-size images. GraphicsMagick can create new images on the fly, making it suitable for building dynamic Web applications. GraphicsMagick may be used to resize, rotate, sharpen, color reduce, or add special effects to an image and save the result in the same or differing image format. [Less]

VIPS

Compare

  Analyzed 1 day ago

The VIPS library/image processing system is well suited for larger than RAM true and false-colour images. VIPS can be used for image format conversion, colour calibration, image filtering, transformation and analysis, thumbnail generation, small object recognition and many other image processing ... [More] tasks. VIPS is well suited for medical and scientific research & development and batch image processing. It is not so good for retouching photographs. The system has two main parts: libvips is the library, and nip2 is the GUI. Both execute common image processing tasks faster than other image processing systems because of sophisticated memory/task management and multicore compatibility. VIPS runs in batch (command line) mode on *nix, Windows, Mac and other OSes. [Less]

NIP2

Compare

  Analyzed about 24 hours ago

nip2, the "free love child of Photoshop and Excel," is the GUI of vips. You don't directly edit images --- instead, like a spreadsheet, you build relationships between objects. nip2 actively manages these relationships: if you change an object property, the change is propagated "spreadsheet-style." ... [More] Like vips, nip2 is fast and needs little memory. You can comfortably work with multi-gigabyte images on very modest hardware. In addition to the visual programming interface accessible through the GUI, nip2 has command-line and batch modes. It even has its own functional programming language (for writing extensions).
