Libraries \ Processing.org

The following libraries are included with the Processing software. To add one to a project, select its name from the "Import Library..." option in the Sketch menu. These libraries are open source; the code is distributed with Processing.

Candy SVG Import

This library has been moved to the Processing core code as of version 149. To load SVG files, check out the reference for PShape(), loadShape(), and shape().

XML Import

This library has been moved to the Processing core as of version 149. To load XML data, check out the reference for XMLElement in the extended reference.

Contributed libraries must be downloaded separately and placed within the "libraries" folder of your Processing sketchbook. To find the Processing sketchbook location on your computer, open the Preferences window from the Processing application and look for the "Sketchbook location" item at the top. Copy the contributed library's folder into the "libraries" folder at this location. You will need to create the "libraries" folder if this is your first contributed library. Follow the links below for more information about each library.

Contributed libraries are developed, documented, and maintained by members of the Processing community. For feedback and support, please post to the Discourse, for development discussions post to Libraries, Tool Development. Instructions for creating your own library are on the Develop Processing site.

On 19 Jan 2009, libraries that had not yet been updated for Processing 1.0 were removed from this list.
