1
 Different ways to display the image
2 Use the webcamxtra cast directly by dragging it onto the stage.
3

Use copyPixels command to display the image onto the stage. In this case, you cannot overlay other sprites on top of the image. It has better playback performance.

Say you have the webcamxtra cast member named webCam.

function startMovie() {
  _global.display = _movie.stage.image;
  member("webCam").findGlobs = true;
}

 

function exitFrame() {
  var m = member("webCam").cameraImage;
  var r1 = m.rect;
  var r2 = _global.display.rect;
  _global.display.copyPixels(m,r2,r1);
  _movie.go(_movie.frame);
}

Use copyPixels command to copy the webcam image onto the image of another bitmap cast member and that cast member has been dragged on the stage as a sprite.

Say, you have a bitmap cast member named "here" of size 320 x 240 which is shown on the stage as a sprite.

function startMovie() {
  _global.img = member("here").image;
  member("webCam").findGlobs = true;
}

 

function exitFrame() {
  var m = member("webCam").cameraImage;
  var r1 = member("webCam").cameraImage.rect;
  var r2 = _global.img.rect;
  _global.img.copyPixels(member("webCam").cameraImage,
    r2,r1);
  _movie.go(_movie.frame);
}
