a while back, toxi posted a great method for asynchronous media loading:
http://processinghacks.com/hacks:dataloadqueue
unfortunately, this code is broken with java 1.6.
PImage will no longer take a BufferedImage, despite the fact that it extends java.awt.Image. this works for me if i force my Mac to run Java 1.5
here's where the error occurs:
in DataBuffer{}:
public PImage getAsImage() {
try {
ByteArrayInputStream bis=new ByteArrayInputStream(bytes);
BufferedImage bimg = ImageIO.read(bis);
return new PImage(bimg);
}
catch(Exception e) {
System.err.println("Can't create image from buffer");
e.printStackTrace();
}
return null;
}
(bytes is simply the raw byte array)
and here's the console output:
java.lang.ClassCastException: [I cannot be cast to [B
I'm not sure exactly how to convert BufferedImage back to java.awt.Image. there is some code here, but its from 2002 and i'm not sure how relevant it is: http://www.java2s.com/Code/Java/2D-Graphics-GUI/ConvertjavaawtimageBufferedImagetojavaawtImage.htm
Another option might be to completely replace toxi's code with MediaTracker, has anyone had sucess with this in Processing?
