image is not beeing drawn

[Andrew Lit]

Hi,

i add canvas into mine form and want to draw an image which i read from file. but when i run the program my canvas draws nothing.
this is how i read the image file:
if i do it like this than it draws me something

  
        Image image;
        byte []image_arr;
        ....  
        String fullPath = "int1.png";
        try {            
            in = new FileInputStream(fullPath);
            image_arr = new byte[in.available()];
            for(int i = 0; i < image.length; i++) {
                image[i] = (byte)in.read();
                //System.out.print("@"+image[i]+" ");
            }     
            in.close();
        } catch(FileNotFoundException fnfe) {
            System.out.println(fnfe.toString());
        } catch(IOException ioe) {
            System.out.println(ioe.toString());
        }
        image = Toolkit.getDefaultToolkit().createImage(
                new MemoryImageSource(width, height,
                generateColorModel(), generatePixels(width, height), 0, width));         
        private static ColorModel generateColorModel() {
            // Generate 16-color model
            byte[] r = new byte[16];
            byte[] g = new byte[16];
            byte[] b = new byte[16];
    
            r[0] = 0; g[0] = 0; b[0] = 0;
            r[1] = 0; g[1] = 0; b[1] = (byte)192;
            r[2] = 0; g[2] = 0; b[2] = (byte)255;
            r[3] = 0; g[3] = (byte)192; b[3] = 0;
            r[4] = 0; g[4] = (byte)255; b[4] = 0;
            r[5] = 0; g[5] = (byte)192; b[5] = (byte)192;
            r[6] = 0; g[6] = (byte)255; b[6] = (byte)255;
            r[7] = (byte)192; g[7] = 0; b[7] = 0;
            r[8] = (byte)255; g[8] = 0; b[8] = 0;
            r[9] = (byte)192; g[9] = 0; b[9] = (byte)192;
            r[10] = (byte)255; g[10] = 0; b[10] = (byte)255;
            r[11] = (byte)192; g[11] = (byte)192; b[11] = 0;
            r[12] = (byte)255; g[12] = (byte)255; b[12] = 0;
            r[13] = (byte)80; g[13] = (byte)80; b[13] = (byte)80;
            r[14] = (byte)192; g[14] = (byte)192; b[14] = (byte)192;
            r[15] = (byte)255; g[15] = (byte)255; b[15] = (byte)255;
    
            return new IndexColorModel(4, 16, r, g, b);
        }
        private byte[] generatePixels(int w, int h, Rectangle2D.Float loc) {
            byte[] pixels = new byte[w * h];
    for(int i=0; i<pixels.length; i++){
    pixels[i] = (byte)(i);
        }
            return pixels;
        }
        public void draw(Graphics g, int x, int y) {
            g.drawImage(image, x, y, null);
        }         

but if i change generatePixels function like this, i get empty window:

 
        private byte[] generatePixels(int w, int h, Rectangle2D.Float loc) {
            return image_arr;  //byte array loaded from file
        }
 

I can't understand what is wrong. I would be really glad if tou helped me

Do you have an old version of generatePixels() hanging around?
You call generatePixels(width, height) but the only method we can see declared is

 private byte[] generatePixels(int w, int h, Rectangle2D.Float loc)  

Is this just an error in the typing or do you have another method in your component that matches that signature?
