Question

I’m am trying to read a .bmp file called circle1.bmp. It is in a package that I have imported into the following file.

So far I have the following code, but when I run the following code I get:

javax.imageio.llOException: Can’t read input file!

public void setUp() throws IOException
{
    BufferedImage image = ImageIO.read(new File("circle1.bmp"));
    byte[][] greenInputData = new byte[30][40];

    for (int x = 0; x < inputData.length; x++)
    {
        for (int y = 0; y < inputData[x].length; y++)
        {
            int color = image.getRGB(x, y);
            //alpha[x][y] = (byte)(color>>24);
            //red[x][y] = (byte)(color>>16);
            greenInputData[x][y] = (byte)(color>>8);
            //blue[x][y] = (byte)(color);
        }
    }
    this.inputData = greenInputData;

    System.out.println(this.inputData);
}

You should try something like

image = ImageIO.read(getClass().getResourceAsStream("path/to/your/file.bmp"));
