GENERAL

SCRATCH supports the OpenFX, or OFX, plug-in architecture. This allows external developers to create customized image manipulation code,which can be used and interacted with directly inside the SCRATCH interface, without passing images out to external applications.

Assimilate Inc. is a founding member of the OpenFX Association http://openeffects.org/ .

An initial list is provided below with links to individual vendors. For the most recent list of supported OFX plug-ins for SCRATCH, visit the ASSIMILATE website at http://www.assimilateinc.com/partners/third-party-partners. Also note these plugins are available directly thru our ASSIMILATE Web Store: https://store.assimilateinc.com/ .

PLUG-IN LOCATION

During startup, SCRATCH automatically searches for Plug-in modules in the following locations, and in this order:

1. [Installation]\bin64\*.node *.spa
2. [Installation]\plugin64\*.node *.spa *.ofx *.ofx.bundle
3. [ProgramData]\plugin64\*.node *.spa *.ofx *.ofx.bundle
4. [Environment:'ASSIMILATE_PLUGINS']\*.node *.spa *.ofx *.ofx.bundle
5. [ProgramFiles]\Common Files\OFX\Plugins *.ofx *.ofx.bundle
6. [Environment:'OFX_PLUGIN_PATH']\*.ofx

For OS X the search paths are

1. /Library/Application Support/Assimilator/Plugins
2. /Library/OFX/Plugins/
3. [Environment:'ASSIMILATE_PLUGINS']\*.node *.spa *.ofx *.ofx.bundle
   
4. [Environment:'OFX_PLUGIN_PATH']\*.ofx

Where [Installation] is the root path of the SCRATCH installation ( c:\Program Files\Assimilate, by default) and [Environment] is a Windows environment variable. ASSIMILATE_PLUGINS can be set to any path and SCRATCH looks for Third-Party Plug-ins under that path.
