Static saveFrames 

pub static saveFrames: SaveFramesInternalType

Capture a sequence of frames that can be used to create a movie. Accepts a callback. For example, you may wish to send the frames to a server where they can be stored or converted into a movie. If no callback is provided, the browser will pop up save dialogues in an attempt to download all of the images that have just been created. With the callback provided the image data isn't saved by default but instead passed as an argument to the callback function as an array of objects, with the size of array equal to the total number of frames.

Note that saveFrames() will only save the first 15 frames of an animation. To export longer animations, you might look into a library like ccapture.js.

Examples

 function draw() {
 background(mouseX);
 }

 function mousePressed() {
 saveFrames('out', 'png', 1, 25, data => {
   print(data);
 });
 }

Parameters

filename

extension ‘jpg’ or ‘png’

duration Duration in seconds to save the frames for.

framerate Framerate to save the frames in.

callback? A callback function that will be executed to handle the image data. This function should accept an array as argument. The array will contain the specified number of frames of objects. Each object has three properties: imageData - an image/octet-stream, filename and extension.
