Fraqtive is a program for drawing Mandelbrot and Julia fractals. It uses a
very fast algorithm and generates high quality, smooth images. It is fully
interactive, allowing for real-time mouse navigation and dynamic generation
of the Julia fractal preview. OpenGL-rendered 3D view of the fractals is
also supported.
g2 is an easy to use, portable and powerful 2D graphics library. It provides a
comprehensive set of functions for simultaneous generation of graphical output
on different types of devices. Presently, the following devices are supported:
PostScript, GIF and X11 (xfig is in development). g2 is written in C (ANSI)
and additionally has a Fortran interface.
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。
