So I see the examples where the webcam is put out to the main drawing window via set or image.  This is great, but in my app I wanna put other stuff out to that and instead just get the jpg when I hit a key.  I have this app that gets the bytes of a PGraphics.  So is there a way to grab snap shot of web cam and then say getBytes on it... ?

I am new to all this graphics stuff or at least the way processing does it, so trying to figure out whats part of the system and whats not.  I wish the video capture had like theCapture.getJPG(); or something that grabs the latest frame...if I knew how to write it...

course then i couldnt say getBytes(theJPG) cause its not a PGraphics, its an PImage I am guessing...



my get bytes is this: (This is borrowed yes).
Code:

/**
   * Get the given PGraphics bytearray
   * @param src the source graphics
   */
  public byte[] getBytes(PGraphics src){

    switch(type){
    case ImageToTwitter.JPEG:
	// We need a new buffered image without the alpha channel
	BufferedImage imageNoAlpha = new BufferedImage(src.width, src.height, BufferedImage.TYPE_INT_RGB);
	src.loadPixels();
	imageNoAlpha.setRGB(0, 0, src.width, src.height, src.pixels, 0, src.width);
	return getBytesJPEG(imageNoAlpha);

    case ImageToTwitter.PNG:
    case ImageToTwitter.GIF:
	ByteArrayOutputStream baos = new ByteArrayOutputStream();
	try
	{
	  ImageIO.write((BufferedImage)src.image, imageType, baos);
	}  
	catch (Exception e)
	{
	  e.printStackTrace();
	  return new byte[0]; // Problem
	}
	return baos.toByteArray();

    case ImageToTwitter.TIFF:
	return getBytesTIFF(src);

    default:
	println("Unknown type");
	return new byte[0];
    }
  }
