compositor
The compositor object allows you to perform actions related to the video compositor.
compositor IDL
interface Compositor {
void pause(int timeout_ms);
void resume();
int getCrc();
};Object Creation
To create a compositor object, first load the brightsign/compositor module using the require() method. Then create an instance of the screenshot class.
var CompositorClass = require("@brightsign/compositor");
var compositor = new CompositorClass();Compositor
pause()
void pause(int timeout_ms) Suspends graphics compositor updates for the specified number of milliseconds (or until the resume() method is called), up to a maximum interval of 10 seconds. While the graphics compositor is paused, no visual elements will be updated (except for HWZ Video, scrolling tickersscrolling tickers, and off-screen Chromium textures). Use this method to combine intensive graphics and layout operations into a single v-sync update.
resume()
void resume()Resumes the graphics compositor if it has been paused with the pause() method.
getCrc()
int getCrc()Returns the CRC of the Y and Cb signals as a single integer. This method allows the script to compare two moments in the graphics output: If the return values differ, then the output is not identical.
