Name param() Examples void setup() { size(100, 100); // Read the value "51" from the following text embedded in an HTML page: // <applet code="param_example" archive="param_example.jar" width=100 height=100> // <param name="back" VALUE="51"> // </applet> String bgcolorStr = param("back"); int bgcolor = int(bgcolorStr); background(bgcolor); } Description Reads the value of a param. Values are always read as a String so if you want them to be an integer or other datatype they must be converted. The param() function will only work in a web browser. The function should be called inside setup(), otherwise the applet may not yet be initialized and connected to its parent web browser.
