loadImage Problem
Apr 28th, 2008, 4:16pm  
Hi guys, I have a multi-class program (separate files for each class) and I can only load jpegs in the main file. If I try to load the same image inside of the classes then it says that the file "f.jpg" is missing or inaccessible (????)

Does anyone know how to fix this??

 Thanks in advance.

it's probably because of the way you're declaring things.  Make sure you declare the image globally in the main section of your class and then initialize it in one of the constructors or methods. post some code so we can see where the problem is.

 Thanks for the help! Sorry for not being more specific.
 I have this folowing class, for now I am just trying to get it to draw an image on the screen. but it's not working.  
 You mean that I have to declare the PImage variable as a global for the hole program? I really don't like that!

-------------------------------------------
class MarkerScreen extends Screen
{
 PImage backgroundImage;
 
 MarkerScreen()
 {
   backgroundImage = loadImage("f.jpg");
 }
 
 void drawScreen()
 {
   image(backgroundImage, 0, 0);
 }
}
-----------------------------------------------

Problem solved,

  The thing is that you can't run the construct on the global definition of the variable.

 So you just declare all your global variables but you can only instanciate them in the setup() method

 I don't know if it's clear... just avoid this at all costs:

--------------------
MyClass variableName = new MyClass();

void setup()
{
}
--------------------


and try to do this all the times:

--------------------
MyClass variableName;

void setup()
{
 variableName = new MyClass();
}
--------------------

Hope it helps someone!!

see you!!
