How do I use a graphics method to pass parameters? Example is below.

private static void getCorners(out float Wx, out float Wy, out float Vx, out float Vy)
{
    // note-- I don't know how to flip the Y axis using this method...
    // this is not a "graphics" method
    // In other words, I should use something like:
    //    flipY(object sender, System.EventArgs e);
    // but don't know the syntax or whatever 

    // I tried to do this:
    //Graphics g = this.CreateGraphic
    //Matrix myMatrix2 = new Matrix(1, 0, 0, -1, 0, 0);  // flip Y axis
    //g.Transform = myMatrix2;
    //g.TranslateTransform(0, 480, MatrixOrder.Append);
    // ...but I get the error:
    // error CS0026: Keyword 'this' is not valid in a static property, static method, or 
    // static field initializer

    Wx = 1.00F;
    Wy = 1.00F;  // make this 1.00 (not 3.00F) down from the TOP since cannot get Y flipped
    Vx = ((Wx- WXmin)*((VXmax-VXmin)+VXmin)/(WXmax-WXmin));  
    Vy = ((Wy-WYmin)*(VYmax-VYmin)/(WYmax-WYmin)+VYmin);
}

From stackoverflow

• The primary problem with your code - the reason it won't compile - is that you are attempting to call an instance method (via the this keyword) from a static method.

  Removing the static keyword from the getCorners method should get you going. Apart from that, I am a little unclear on what you are asking. For more help on graphics programming in windows forms, here is a brief tutorial.
