Question

I’m trying to use some code like is seen on another questions answer: https://stackoverflow.com/a/621849/1044984

Upon using this I get the following error:

Exception in thread "AWT-EventQueue-0" java.awt.image.RasterFormatException: (y + height) is outside of Raster

Here is the code relating to this error:

try {

            tileSheetBig = ImageIO.read(new File("sprites/tiles.png"));
            charSheetBig = ImageIO.read(new File("sprites/player.png"));

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

        final int tileWidth = 64;
        final int tileHeight = 64;
        final int tileRows = 1;
        final int tileCols = 11;
        tileSheet = new BufferedImage[tileRows * tileCols];

        for (int i = 0; i < tileRows; i++) {
            for (int j = 0; j < tileCols; j++) {
                tileSheet[(i * tileCols) + j] = tileSheetBig.getSubimage(i
                        * tileWidth, j * tileHeight, tileWidth, tileHeight);
            }
        }

        final int charWidth = 16;
        final int charHeight = 23;
        final int charRows = 2;
        final int charCols = 3;
        charSheet = new BufferedImage[charRows * charCols];

        for (int i = 0; i < charRows; i++) {
            for (int j = 0; j < charCols; j++) {
                charSheet[(i * charCols) + j] = charSheetBig.getSubimage(i
                        * charWidth, j * charHeight, charWidth, charHeight);
            }
        }

Since not much was changed from the code provided on the answer I can not see what the issue may be. I’ve tried to google the error but not many answers out there relate to my issue.

Answer 1

That RasterFormatException is thrown by getSubImage() when the area specified by [ x,y : x+width, y+height] is not contained within the BufferedImage area.

Check that your tiles.png image is at least 704×64 px (width*cols,height*rows) and similarly that player.png is at least 48×46 px.

EDIT:
sorry i didn’t notice it at first glance; player.png has to be 32×69 px and tiles.png 64×704 px

EDIT 2:
this fixes your code for the player without editing the sprites; do the same for the tiles

final int charWidth = 64;
final int charHeight = 64;
final int charCols = 11;
final int charRows = 1;
for (int i = 0; i < charCols; i++) {
    for (int j = 0; j < charRows; j++) {
        charSheet[i * charRows + j] = charSheetBig
          .getSubimage(i * charWidth, j * charHeight, charWidth, charHeight);
    }
 }
