Spencer Thomas said about the original TCL GD:
Thomas Boutell's Gd package provides a convenient way to
generate PNG images with a C program. If you, like me, prefer
Tcl for CGI applications, you'll want my TCL GD extension.
The software is now maintained by John Ellson <ellson@lucent.com>, it
seems.
GEGL (Generic Graphics Library) is a graph based image
processing framework.
GEGL provides infrastructure to do demand based cached
non destructive image editing on larger than RAM buffers.
Through babl it provides support for a wide range of color
models and pixel storage formats for input and output.
The goal of the OpenGL Extension Wrangler Library (GLEW) is to assist
C/C++ OpenGL developers with two tedious tasks: initializing and using
extensions and writing portable applications. GLEW provides an efficient
run-time mechanism to determine whether a certain extension is supported
by the driver or not. OpenGL core and extension functionality is exposed
via a single header file.
epstool - Create or extract preview bitmaps in EPS files.
Features:
- Add EPSI or DOS EPS previews.
- Extract postscript from DOS EPS files.
- Uses Ghostscript to create preview bitmaps.
- Scan a bitmap created by Ghostscript to find bounding box.
- Create TIFF or Interchange from part of a bitmap created
by Ghostscript.
feh is a versatile and fast image viewer using imlib2, the
premier image file handling library. feh has many features,
from simple single file viewing, to multiple file modes using
a slideshow or multiple windows. feh supports the creation of
montages as index prints with many user-configurable options.
GLFW is a free, Open Source, multi-platform library for OpenGL application
development that provides a powerful API for handling operating system specific
tasks such as opening an OpenGL window, reading keyboard, mouse, joystick and
time input, creating threads, and more.
A simple graphics library, designed to give the programmer access to
most interesting parts of the Win32 Graphics Device Interface and X11
library without exposing the programmer to the pain and anguish usually
associated with using these interfaces. The library also includes a
module Graphics.SOE providing the interface used in "The Haskell School
of Expression", by Paul Hudak.
jpg2pdf 是一个能把一个或多个 JPG 图像转成一个单一的 PDF 或 PostScript 文件
的程序。
和其它类似的程序相比,jpg2pdf 的主要有点在于其小巧、快速且完全由 C 语言写
成。
它可以通过使用适当的 PDF 或 PS 规则直接包装 JPG 数据,因此没有图像转换工作。
Kludge3d is a simple 3d editor, in the spirit of Worldcraft or Milkshape.
It is the offspring of several other (presumably abandoned) GTK-based editors,
with the best features taken from each. As the name implies, kludge3d is
exactly that - a kludge.
This package provides encoder/decoder implementation for DEC SIXEL graphics,
and some converter programs.
SIXEL is one of image formats for terminal imaging introduced by DEC VT series.
Its data scheme is represented as a terminal-friendly escape sequence.
So if you want to view a SIXEL image file, all you have to do is "cat" it to
your terminal.
