Using the loadImage() function on an image that doesn't exist throws an exception and halts processing.

Would it be possible for loadImage() to return a boolean regarding the existence of the file / url it's being fed?

I'm not implying anything about the nature of the picture, don't get missunderstood with the name of the file.  jejejeje

I am seeing this same problem.  Processing halts and will not continue when a file is not found with loadImage method.  

I can catch the exception, but I can not seem to continue processing.


Here is my code:
Code:

boolean getImageById(int Id) {
  
  String f = "thumb" + Id + ".jpg";
  
  try {
    PImage p = loadImage(f);
    doSomethingWith(p); 
 } catch (Exception e) {
    println(f+" file not found");
    return false;
  }
  return true;
}
 

Here is the error I get when a file is missing:
-----------------------------------------------------
java.io.IOException: openStream() could not open D:\folded\thumb161.jpg

This is Processing 0091 in Windows XP, JRE 1.4.2.  

Thanks for any help!

I tried the code above, and it seemed to work fine:
Code:

  try{
    PImage img = loadImage("http://wliia.org/bob.gif");
  }catch (Exception e){
    println(e);
  }
 

I only get the exception printed out, and the program continues.. :)
