How to Print Picture Box in C#
To print a PictureBox
in C#, you typically need to perform the following steps
Drag and drop the PictureBox and Button controls from the Visual Studio toolbox to your winform, then layout your form as shown below.
Add a click event handler to the Open button allows you to select an image, then display on the PictureBox control.
private void btnOpen_Click(object sender, EventArgs e) { //Open image file using (OpenFileDialog ofd = new OpenFileDialog() { Filter = "JPEG|*.jpg", ValidateNames = true }) { if (ofd.ShowDialog() == DialogResult.OK) pictureBox.Image = Image.FromFile(ofd.FileName);// set image to picturebox } }
Add a click event handler to the Print button allows you to print an image from the PictureBox as the following c# code.
We will create a PrintDocument
object, then handle the PrintPage
event of the PrintDocument
object to specify what content to print.
private void btnPrint_Click(object sender, EventArgs e) { //Show print dialog PrintDialog pd = new PrintDialog(); PrintDocument doc = new PrintDocument(); doc.PrintPage += Doc_PrintPage; pd.Document = doc; if (pd.ShowDialog() == DialogResult.OK) doc.Print(); }
Creating the PrintPage event handler allows you to print an image using PrintDocument to the printer.
private void Doc_PrintPage(object sender, PrintPageEventArgs e) { //Print image Bitmap bm = new Bitmap(pictureBox.Width, pictureBox.Height); pictureBox.DrawToBitmap(bm, new Rectangle(0, 0, pictureBox.Width, pictureBox.Height)); e.Graphics.DrawImage(bm, 0, 0); bm.Dispose(); }
When you click the Print button, it will show a print dialog allowing you to select a printer and then print the content of the PictureBox
.
Through this c# example, you can easily print an image from the PictureBox in c# windows forms application.
