Thread: problems getting past the out of bounds error

I know this is basic but I am in an into class doing this...I have a method to copy a picture onto a white background. I need to be able to make it so that when I put in coordinates it will not go out of bounds and will just cut part of the picture off and show the rest any help would be great. I know I need an if loop or two in there I just can not get it to work Here is the code I have: I am also using dr java to write everything

public void copyPicture(Picture picToCopy, int startX, int startY){
 
       Pixel pSource = null;
       Pixel pTarget = null;
       int offsetX = startX, offsetY=startY;
 
            for (int x=0; x<picToCopy.getWidth(); x++){
         for ( int y = 0; y<picToCopy.getHeight(); y++){
           pSource= picToCopy.getPixel(x,y);
           pTarget= this.getPixel(offsetX+x,offsetY+y);
           pTarget.setColor(pSource.getColor());
         }//end y loop
       }//end x loop
 
         return;
         }
 //end copyPicture

Carefully go through the logic of your loops. If you loop through the entire width/height, adding an offset other than 0 will at some point take you out of bounds. Either loop from offset forward, or from 0 to offset, depending upon your needs.

Maybe a long shot but...this isn't for Troy's class is it?

Anways, do you want to just copy a part of the picture, and have white space next to it? Or do you want nothing next to it at all, and only have the piece of the window you want, which essentially is "cropping".
