I was modifying my spritesheet loading class to use 64x64 sized images from another sheet, and it now throws this error:

package com.natekramber.gfx;

         ;
   public BufferedImage sheet16, sheet64
      ;
   public BufferedImage[] sprites16, sprites64;
   
   public SpriteSheet() {
      try {

      } catch (IOException e) {
         e.printStackTrace();
      }

      } catch (IOException e) {
         e.printStackTrace();
      }
     
      sprites16 = new BufferedImage[rows16 * cols16];
   
      for (int i = 0; i < rows16; i++) {
         for (int j = 0; j < cols16; j++) {
            sprites16[(i * cols16) + j] = sheet16.getSubimage(
                     i * width16 + i * 3,
                     j * height16 + j * 3,
                     width16,
                     height16
                 );
         }
      }
     
      sprites64 = new BufferedImage[rows64 * cols64];
     
      for (int i = 0; i < rows64; i++) {
         for (int j = 0; j < cols64; j++) {
            sprites64[(i * cols64) + j] = sheet64.getSubimage(            //    <--Error is thrown here, line 47
                  i * width64 + i * 3,
                  j * height64 + j * 3,
                  width64,
                  height64
               );
         }
      }
   }
}


Why is it doing this? I have the exact same code for another game, and it doesn't throw any errors. It's even almost the same for the loader above it.

Thanks,

It's pretty simple: just like the exception message says: your sub-image is not fully contained in the parent image.

Check your coords.
