Another question bugs me
Aug 13th, 2009, 6:41pm  
I'm using loadImage("URL") to retrieve pictures from a webcam. So far everything is fine. The pictures come flowing in. But every now and then, one of the images seems to be corrupted.
In these cases i get an orange error alert in the console-area of the sketch window saying:
Corrupt JPEG data: bad Huffman code
or
Premature end of JPEG file

And that's it.
The PImage is not null and has width != -1. I can loadPixels() and pixels.length is the full value as the good pictures.
But the image is broken!
It contains only a few lines of content and then zero.

What can i do to catch this error?

You may be able to surround the loadImage() call with a try/catch block.
Look up the exact error to catch, or just assume that the bad Huffman code was found.
Code:
try {
  loadImage("source.jpg");
} catch(Exception er) {
  //something bad happened
  er.printStackTrace(); //I would expect this to print out the same error
}
