Hasin Hayder has provided some instructions he's created to install the Imagick extension for PHP on a Ubuntu linux system (7.10) in a new blog entry.   I already have ImageMagick installed in my machine and I tried to install the Imagick extension for PHP but I was stuck with strange errors. I have spent couple of hours today to figure out what I did wrong and Why I cant build that extension. Finally I've figured out that I must install ImageMagick from source first to build that extension. Heres how to.   He walks through the install, talking about where to get the package from, where to get the PECL extension for PHP and the compile process (with the result of a .so file PHP's extension can use).

Kore Nordmann has written up some benchmarks of some of the more popular PHP image creation libraries testing their output times and results for generating the same image.   In my article series I showed several ways on how to create images with PHP, going into implementation details etc. Now I just want to provide a very rough overview on speed and quality of the extensions.   He ran them with some settings disabled to optimize things as they ran and came up with results pointing to Cairo being the fastest to generate and output the image. It also had the benefit of outputting an image with the highest quality of the five tested (Cairo, SVG, Flash and GD with and without supersampling). His benchmark code is also included.

Read and Write ICO,BMP formats in 100% pure Java   Been a long time in the making, but I've finally gotten round to the final release for 0.7  The library appears to be stable, hence my decision to finalize the current release.  Thanks to Olivier Le Tiec for reporting a bug with irregular icons (width != height), together with the necessary bug fix.  Thanks for using image4j!

On the Zend Developer Zone, they point out a handy little image manipulation class they've come across - GenXDesign's PHP Thumbnail Class - as well as some details about it.    I've seen a lot of implementations of thumb nail functionality in PHP, I've even written a couple of my own. I like this class thought. In looking over the code the first thing you notice is that it's clean code. I don't mean they use the latest whiz-bang method to cshave a few keystrokes.    This code is simple, nicely formatted and easy to read through. My only real problem with the code itself is that it is not terribly well documented. That can be forgiven since easy to read.    Cal talks about some of the other features of the class, including that it works with gif/jpeg/png images, makes it easy to set the quality of the jpgs, and makes it easy to display the dynamic images directly to the browser. Check out the demo for more.

The CImg Library provides a set of C++ classes that can be used in your sources, to load/save, process, display images. Portable (Unix/X11,Windows, MacOS X,..), efficient, simple to use, it's a pleasant toolkit for coding image processing stuffs in C++.   The CImg 1.2.4 package have been released. This is a minor release but with interesting stuffs anyway.  *----------------------------- *----------------------------- * Changes from 1.2.3 to 1.2.4 *----------------------------- *-----------------------------  * New features : - Added macro 'cimg_for_lineXY(x,y,x0,y0,x1,y1)' that loops over an image segment (x0,y0)-(x1,y1). - Added function 'CImg::draw_polygon()' that draws a filled polygon of any shape in the instance image. - Added macros 'cimg_load_plugin', 'cimg_save_plugin', 'cimglist_load_plugin' and 'cimglist_save_plugin' allowing to easily add file support for your own data format. - Added plugin 'plugins/add_fileformat.h' to show how to use these new macros to register a new image format in CImg. - Added version of 'CImg[List]::{load,save}_cimg()' that is able to read/write only sub-images of data stored in a (big) .cimg file. - Added an online chat on the CImg website, so that users can interact freely.  * Optimizations / Modifications : - Added functions 'CImg[List]::save_empty_cimg()' that can be used to work with very large images. You can now create first an empty (big) image, then load/save sub-images into this big .cimg file, without needing much memory. - Slightly modified the header of .cimg files, so little/big endian info is stored. - Reorganized some 'CImg[List]::load_*()' functions, trying to avoid unnecessary memory usage. - Recoded versions of CImg::draw_triangle() that now use the Bresenham's algorithm for interpolation (more precise, while using only integer calculus). - Added versions of 'CImg::draw_triangle()' and 'CImg::draw_line()' that are able to map textures while correctly handling the perspective correction, so that 3D mapped triangles look correct now.  * Bug corrections : - Corrected a small bug in get_coordinates() : channels of hyperspectral images with (dim>3) where subsampled instead of cropped for image visualization. - And many small bug corrections...

We have some big news today for FlickrFan users, a major new source of high-def photography for the networked living room. They come from Agence France-Presse, one of the world's great news organizations, and a fantastic source of high-resolution news photography. I met with Agence France-Presse when I was in Paris in December, introduced them to FlickrFan and explained what we were doing with the Associated Press. They got excited, it took a little while to work out the technical details, but now we're ready to go. The updates are all out, here's the howto for FlickrFan users. Change #30: Agence France-Presse photos in FlickrFan. There were unique challenges in this project because their flow is huge. Yesterday we got over 3000 new photos. Because there are so many, I asked my friend Matt Mullenweg, if his company Automattic could help us out with server space and bandwidth, and he said yes. The AFP pictures are hosted on wordpress.com. Many thanks to Matt and his company for helping us out. To the extent we're bootstrapping a new use of the net, which I hope is what we're doing, Matt's company has made the kind of contribution we'd like to see more companies make. Usually the companies are happy to make the money, but not willing to help out with the bootstrap, which often costs money. Matt has always been a great guy and a visionary. I thank him and hope that FlickrFan users find an appropriate way to thank him too. And also, please consider the generosity of Associated Press and Agence France-Presse. We all hope that there's a market here, a way to monetize the flow of high-resolution photography to enrich and inform. Other content companies have been reluctant to take a chance on the Internet, we saw that in the early days of RSS and podcasting. I feel that these two media companies are playing the same pioneering role that the New York Times played with RSS 2.0 and NPR played in podcasting. Associated Press and Agence France-Presse deserve our respect and admiration for steping out, for going first, this is how new Internet activities get going. This is what we call market leadership, the real kind. Bravo!! And this couldn't come at a better time, with tomorrow being Super Tuesday here in the USA. Think of all the great photographs we're going to get in the next few days! Kevin Tofel helped test the feed over the weekend.

This is a cool little feature I've been wanting for a while now.  Every once in a while I'll develop some cool feature in some software that I'm writing and want to show off a screenshot.  The only problem is that without showing how it interacts with the user I can't demo the features raw power.  An animated screenshot would solve this but no existing screenshot tools support animated gif output.  It turns out that 'convert' from ImageMagick supports. Ksnapshot can be used to grab the screens and 'convert' can stitch them together.  Heres what you do:  - Startup ksnapshot and take a series of snaps from your application.  Each   snapshot should be an independent frame in the series.  - Save ...

For years, you couldn't go wrong by letting one number drive your digital-camera shopping: the  megapixels, or millions of picture elements, that the camera could record in an image.

Here's an interesting Howto on connecting FlickrFan to the Mac desktop. I love this stuff.  Here's a movie that demonstrates this coolest of hacks.
