XMagick - Integrate ImageMagick with any X Application

ImageMagick is a robust collection of tools and libraries to read, write, and manipulate an image in any of the more popular image formats including GIF, JPEG, PNG, PDF, and Photo CD. With ImageMagick you can create GIFs dynamically making it suitable for Web applications.

XMagick is a library written in C, which allows integration of the ImageMagick library with any X application by providing functions which convert between the native X image format (XImage) and the native ImageMagick format (Image).

Status

#!/bin/sh # If the file oldnews.shtml is present, it will contain a list of # all the release notes. In that case we only need to list the most # recent one here. oldnews() { f=`echo $news|cut -f 1 -d ' '` s=`basename $f .shtml | cut -c 6-` echo "News in $s" echo "

Version 0.0.1 caches results from XAllocColor and XQueryColor, speeding things up dramatically. Autoconfiguration of shared and static versions of the library. New Magick widget and demo program.

Version 0.0.2 adds autoconfiguration for the example programs.

Version 0.0.3 further optimizes the colour cache, speeding up lookups and making XMagickImageToXImage faster. See ChangeLog for details.

Version 0.0.4 makes a linear search for a best match if XAllocColor fails. It also adds manpages for the library and functions.

Version 0.1.0 is updated to support ImageMagick 5.2.0.

Version 0.2.0 is updated for ImageMagick 5.5.0. It is also much faster.

This code has been tested on Linux and Solaris. Reports of success or failure on other systems are welcome.

Examples

These two examples are included with the library, but not built by default.

A Widget

demo.c
Magick.c
Magick.h
MagickP.h

This program displays an image in a custom widget. The name of the image to display is given on the command line.

Basic Conversion

demo2.c

This program reads an image, converts the Image to an XImage and back, and stores the result. It can be used to convert between any formats supported by ImageMagick.
