Draw a Bitmap image on the screen

Question

Im trying to print (show in screen ) a screenshot on my main monitor , I think I’ve got all the necessary variables to make that happen but I have no clue how to get past “ PaintEventArgs” . What should I send, how should I do it?

EDIT: Here is what I want to do http://msdn.microsoft.com/en-us/library/8tda2c3c.aspx

static void Main(string[] args)
{
    Rectangle rect = Screen.PrimaryScreen.Bounds;
    int color = Screen.PrimaryScreen.BitsPerPixel;
    PixelFormat pf;
    pf = PixelFormat.Format32bppArgb;           
    Bitmap BM= new Bitmap(rect.Width, rect.Height, pf);
    Graphics g = Graphics.FromImage(BM);
    g.CopyFromScreen(rect.Left, rect.Top, 0, 0, rect.Size);
    Bitmap bitamp = new Bitmap(BM);
    print (bmp,) // what now?

}

private static void print(Bitmap BM, PaintEventArgs e)
{
    Graphics graphicsObj = e.Graphics; // or "Bitmap bitmap = new Bitmap("Grapes.jpg");"
    graphicsObj.DrawImage(BM, 60 ,10); // or "e.Graphics.DrawImage(bitmap, 60, 10);"
    graphicsObj.Dispose();
}

PS: this is my first time using the site so excuse any noobish mistakes I might have made

Answer 1

The simplest way would be to use a Windows Forms PictureBox inside a Form.

For example:

Form form = new Form();
form.Text = "Image Viewer";
PictureBox pictureBox = new PictureBox();
pictureBox.Image = YourImage;
pictureBox.Dock = DockStyle.Fill;
form.Controls.Add(pictureBox);
Application.Run(form);

You'll need to call print(Bitmap, PaintEventArgs) within the form Paint event.

Try this

private void Form1_Load(object sender, EventArgs e)
{
    Paint += new PaintEventHandler(Form1_Paint); //Link the Paint event to Form1_Paint; you can do this within the designer too!
}
private void print(Bitmap BM, PaintEventArgs e)
{
    Graphics graphicsObj = e.Graphics; //Get graphics from the event
    graphicsObj.DrawImage(BM, 60, 10); // or "e.Graphics.DrawImage(bitmap, 60, 10);"
    graphicsObj.Dispose();
}

private void Form1_Paint(object sender, PaintEventArgs e)
{
     Rectangle rect = Screen.PrimaryScreen.Bounds;
     int color = Screen.PrimaryScreen.BitsPerPixel;
     PixelFormat pf;
     pf = PixelFormat.Format32bppArgb;
     Bitmap BM = new Bitmap(rect.Width, rect.Height, pf); //This is the Bitmap Image; you have not yet selected a file,
     //Bitmap BM = new Bitmap(Image.FromFile(@"D:\Resources\International\Picrofo_Logo.png"), rect.Width, rect.Height);
     Graphics g = Graphics.FromImage(BM);
     g.CopyFromScreen(rect.Left, rect.Top, 0, 0, rect.Size);
     Bitmap bitamp = new Bitmap(BM);
     print(bitamp, e);
}

Thanks,
I hope you find this helpful :)

make it simple just.

    //Draw Image

    // location of you image
    Bitmap img = Properties.Resources.myImage;

    // set image 
    Image newImg = img;

    // draw a image
    e.Graphics.DrawImage(newImg, 180F, 18F, newImg.Width, newImg.Height);

I have a very good solution, but you need to calculate the position and sizing for your stuff. Unfortunately, I have not figured out how to draw an img to screen yet.

using System;
using System.Drawing;
using System.Runtime.InteropServices;
using System.Threading;

namespace DIRECTDRAW
{
    class Program
    {
        [DllImport("user32.dll")]
        static extern IntPtr GetDC(IntPtr hwnd);

        static void draw(Rectangle r, Brush b, IntPtr hwnd)
        {
            using (Graphics g = Graphics.FromHdc(hwnd))
            {
                g.FillRectangle(b, r);
            }
        }

        static void Main(string[] args)
        {
            int w = 5;
            int h = 5;

            Point xy = new Point(960 - w, 540 - h);
            draw(new Rectangle(xy, new Size(w, h)), new SolidBrush(Color.White), GetDC(IntPtr.Zero));
            Thread.Sleep(1);
            Main(args);
        }
    }
}

I put in a loop function so that your "thing" doesn't disappear, and I made the wait part at 1 milisecond so that the dot doesn't flicker. Thankfully it's a console app so it won't freeze.

Found this solution out from Draw Directly To Screen.

Answer 5

Every example I tried didn't work. here's my code that worked for me.

using System.Drawing;
using System.Windows.Forms;

//create your bitmap

 Form1 form1 = new Form1(bitmap);


public class Form1 : System.Windows.Forms.Form
{
    Bitmap bitmap;
    public Form1(Bitmap bitmap)
    {
        this.bitmap = bitmap;
        this.ClientSize = new System.Drawing.Size(this.bitmap.Width, this.bitmap.Height);
        this.Paint += new System.Windows.Forms.PaintEventHandler(this.Form1_Paint);
        Application.Run(this);
    }
   
    private void Form1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
    {
        Graphics gForm = e.Graphics;
        gForm.DrawImage(bitmap, 0, 0, bitmap.Width, bitmap.Height);
        bitmap.Dispose();
    }
}
