Question

I don't know how to fix this, the code is to lighten the image but I keep coming across this error and I can't seem to fix it

/** CORE:
     * Make all pixels in the image lighter by 20 greylevels.
     * but make sure that you never go above 255
     */
 public void lightenImage(float value){
        if (value == 0) return;
        
        boolean darken = value < 0;
        value = Math.abs(value);
        for (int x = 0; x < this.image.length; x++)
        for (int y = 0; y < this.image[0].length; y++) {
        Color pixel = this.image[x][y];
        float r = (float)pixel.getRed() / 255;
        float g = (float)pixel.getGreen() / 255;
        float b = (float)pixel.getBlue() / 255;
        float a = (float)pixel.getAlpha() / 255;                
        
        r = darken ? r * (1 - value) : r + (1 - r) * value;
        g = darken ? g * (1 - value) : g + (1 - g) * value;
        b = darken ? b * (1 - value) : b + (1 - b) * value;
        this.image[x][y] = Color(r, g, b, a);
        }
        
    }

What error do you get? What is `this.image`? Please [edit] your question and make it a [mcve]. See [ask]. — Robert, May 31 '22 at 03:35
The last line of your code does not compile. I am referring to this line: `int image[x][y] = Color(r, g, b, a);` Are you sure that is your actual code? — Abra, May 31 '22 at 03:58
@Abra this is my code. If i used this.image it would result in an error, saying that "Java.awt.color can not be converted into a int". So i played around with it and happened to do"int image [x][[y]"t by mistake. Apologies for that. — Zynbad, Jun 01 '22 at 03:54
@MohamadGhaithAlzin There are 2 errors. One saying that "Java.awt.color cannot be convered to int" for this linethis.image[x][y] = Color(r, g, b, a); — Zynbad, Jun 01 '22 at 03:58
@MohamadGhaithAlzin And also one for this line Color pixel = this.image[x][y]; — Zynbad, Jun 01 '22 at 03:58
@MohamadGhaithAlzin it says int cannot be converted to colour — Zynbad, Jun 01 '22 at 03:58
@Zynbad For reading the Color try using this `Color pixel = new Color(image.getRGB(x, y));` — Mohamad Ghaith Alzin, Jun 01 '22 at 04:17
Then, for reading the Red, Green & Blue try `int red = pixel.getRed();` & `int green = pixel.getGreen();` & `int blue = pixel.getBlue();` — Mohamad Ghaith Alzin, Jun 01 '22 at 04:21
The `image` should be read as `BufferedImage`. Are you using `BufferedImage`? — Mohamad Ghaith Alzin, Jun 01 '22 at 04:23
