    Question Creating an Image Editor Application

    Hello all,
    I want to create an application for Image Editor. I've created a simple Image Editor, like ms.Paint with less features, only can draw rectangle, line, and ellips, erase things, etc, and no canvas (u can draw everywhere on form.
    I want to create a new one, which able to do more, like using canvas, there's layers, able to insert image,etc.
    There is a lot of questions I wanna ask.
    First of all, I found out that C# has Canvas class, how to use it ?
    I'm using this code :

    private void Editor_Load(object sender, EventArgs e)
    {
    Canvas myCanvas = new Canvas();
    myCanvas.Width = 500;
    myCanvas.Height = 200;
    myCanvas.VerticalAlignment = System.Windows.VerticalAlignment.Top;
    myCanvas.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
    }

    There is nothing happened. Are there is anyway to create Canvas with tools ? If there isn't, please anyone tell me how to use canvas..
    and also, are we able to draw on canvas ?

    Re: Creating an Image Editor Application

    you can use Bitmap with one of its constructors for (width/ height) as canvas.
    cosider this code example:

    Code:
        private void button3_Click(object sender, EventArgs e)
            {
                Image img = CreatePicture();
                pictureBox1.Image = img;
                
            }
    
            private Image CreatePicture()
            {
                // Create a new Bitmap object, 50 x 50 pixels in size 
                Image canvas = new Bitmap(50, 50);
                // create an object that will do the drawing operations 
                Graphics artist = Graphics.FromImage(canvas);
                // draw a few shapes on the canvas picture 
                artist.Clear(Color.Lime);
                artist.FillEllipse(Brushes.Red, 3, 30, 30, 30);
                artist.DrawBezier(new Pen(Color.Blue, 3), 0, 0, 40, 15, 10, 35, 50, 50);
                artist.Dispose();
                return canvas;
            }

    yes, it is possible if you also combine it with AJAX or write an ActiveX for it.

    Re: Creating an Image Editor Application

    yes there are. you can search google.
    also there are good books about GDI+ that learn you everything about it.
    also there are some articles in codeproject site; go and search there.

    also for simple issues like how to draw line, curve, shapes you can search in the MSDN.
    for specific problems ask here you could not accomplish something.
