Adobe Illustrator | Javascript

🚧

Documentation under development.

The Adobe Illustrator extension primarily builds upon

gRPC via Javascript but deals with some particularities of Adobe extensions. To run the extension, copy the folder to C:\Program Files\Common Files\Adobe\CEP\extensions

You will need to enable debugging, we recommend using that third-party software for it: ‣

It was only tested on Adobe Illustrator, though with some changes it should also work e.g. in Photoshop.

Draw some curves, “Connect” with PRC, select them and click “Update Toolpath” to turn the curves into toolpaths and send them to PRC for simulation and code generation.

You can connect to localhost:8004 to debug the Javascript code.

was used to design the user interface, therefore the relevant *.css and *.js files are imported.

The interaction happens through the hostscript.jsx file, which uses ExtendScript (basically an older Javascript dialect) to interact with Illustrator. To be able to exchange data,

json.jsx

indiscripts

is used to serialize and deserialize.

In the hostscript.jsx, GetToolpath() gets the currently selected curves and uses their anchor points for linear movements. Consider using Path/Add Anchor Points to add more points and then Path/Simplify to reduce them again locally.

Currently, the base values are only updated if you set them before clicking Connect. Otherwise use the settings in the PRC browser-based UI.
