Image creation, conversion and manipulation with ImageMagick

March 26, 2006

ImageMagick logoImageMagick consists of a set of powerful, open-source (free!) routines used to create and edit images. These can be called directly, i.e. by web pages, batch programs, software you're writing, or via the appropriate interface for your platform. ImageMagick is available for all major operating systems.

ImageMagick handles over 90 formats, including GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD and TIFF. Crop, resize, stretch, rotate; sharpen, color-reduce your palette, make the image transparent, or sepia-tone it. Merge images or combine them into an animated GIF. Add text, lines, polygons, ellipses and BΘzier curves.

Of course, nothing is perfect. The number of options are overwhelming: it's almost impossible to visualize the enormous range of possibilities these routines offer. Complex commands take time to craft. And my web hosting service no longer permits the PHP exec() command - it can open the door for crackers. If they can upload one .php file, they can destroy your system. [ Examples of ImageMagick usage, and full review ... ]



SourceForge.net: premium archive of freeware and public domain code projects

March 20, 2006

Trying something new? Fifty to one someone else has already tried.

SourceForge logoSourceForge.net is the world's largest Open Source software development web site, hosting more than 100,000 projects and over 1,000,000 registered users with a centralized resource for managing projects, issues, communications, and code. SourceForge.net has the largest repository of Open Source code and applications available on the Internet.

Check here first to see what you might be missing. Find code you can use without restriction, whole or in chunks. Some projects may be inactive, but even then their code could be of use. You could even revive the project if you wanted, and create the Next Great Code.



Composing and formatting blog text using HTMLArea Composer

March 6, 2006

We're still in the process of coding the engine to store and serve new content. Part of the process - developing an easy-to-use interface for integrating and formatting text, graphics, links, etc. HTMLArea Composer fit the bill perfectly, though on-going development seems nebulous. The SourceForge home page does not seem to link to downloadable code - I found it at www.alloysoftware.com.
