Pierre-Alain Joye's Blog:
5.1.3 is out, Congrats! (and finally)
May 02, 2006 @ 07:08:44

Pierre-Alain Joye has a quick post with a congratulations to the entire team (and testers, etc) that worked to get PHP 5.1.3 out the door.

He also specifically mentions two GD updates that were made to this new release - new compression filtering for the imagepng functionality, and a "weak mode" for imagejpeg. This new mode can be set in your php.ini file or with ini_set (gd.jpeg_ignore_warning).

To grab the latest PHP update, including these new features to the graphics libraries, head over to the main PHP site.

Pierre's Blog:
imagepng, take #2
January 30, 2006 @ 07:37:31

Pierre has posted his second look at working with the imagepng function today over on his blog.

Bernhard Seefeld was testing the new compression option for imagepng and was wondering why there is still a relative big difference in image sizes.

In my first attempt to create smaller images, I only allowed to change the compression, it was not sufficient to get really lite pictures.

After a short look to the libpng codebase (and the horrible imagick doc), I added a last argument to imagepng, the filtering mode.

He includes code later in the post, showing how to use this filtering option to make even smaller images (an option included from PHP 5.1.3 and up).
