Winform Image Control

Question

I convert code from WPF to Winforms. Does winforms have an Image control instead of a picture box image. WPF has an Image control where I am trying to capture an image. I am getting an error trying on the code below.

Error: you cannot convert System.Windows.Media.ImageSource to PictureBox. How to achieve this in winforms

pbImage.Image = (ImageSource)ImageSource; // Error

If you just want to convert your System.Windows.Media.ImageSource object to System.Drawing.Bitmap or System.Drawing.Image so that you can show it in a PictureBox control check the following link: https://stackoverflow.com/questions/1201518/convert-system-windows-media-imagesource-to-system-drawing-bitmap But if you are looking for more advanced .NET WinForm image viewer control you can check the ImageViewer control from LEADTOOLS: https://www.leadtools.com/help/leadtools/v19m/dh/c/imageviewer.html This control (class) provides many advanced features that can help you to view and control images display in your WinForms application. Also the RasterImageConverter class provides methods that can help you to convert a Leadtools.RasterImage object to and from Windows Presentation Foundation (WPF). More details can be found here: https://www.leadtools.com/help/leadtools/v19m/dh/wm/rasterimageconverter.html

Anyway you will not get access to ImageSource from (PresentationCore.dll) in Winform Application. But you might have a physical imagefile file or a path to the file location. or gather you image files from your WPF project and try the following. GetFileLocation will return path. (in your case this funtion should retrieve the path where you were using for WPF) string imageFileLocation = GetFileLocation(); pictureBox1.ImageLocation = imageFileLocation; //Example pictureBox1.ImageLocation = @ C:\images\myphoto.jpg ; Hope this will help you.

Hey There is no direct way to convert it because both have different aspects There are 2 ways to get your result 1. Use ElementHost control to host wpf control to winform https://www.codeproject.com/Articles/739902/How-to-Easily-Host-WPF-Control-inside-Windows-Form 2. You can save your ImageSource to MemoryStream and then show it on picturebox as something suggested by Sundar

Try the following codes ImageSource imageSource = new BitmapImage(new Uri(C:\FileName.gif)); image1.Source = imageSource; Code 2 private System.Drawing.Bitmap BitmapFromSource(BitmapSource bitmapsource) { System.Drawing.Bitmap bitmap; using (MemoryStream outStream = new MemoryStream()) { BitmapEncoder enc = new BmpBitmapEncoder(); enc.Frames.Add(BitmapFrame.Create(bitmapsource)); enc.Save(outStream); bitmap = new System.Drawing.Bitmap(outStream); } return bitmap; }

you want to draw the picture without any control but show it as a background and you don't want to set the background-Image than you can do like the following sample: public partial class Form1 : Form { public Form1() { InitializeComponent(); SetStyle(ControlStyles.ResizeRedraw true ); InitilizePicture(); } Bitmap b = new Bitmap(1600 900); Rectangle rect; Rectangle sourceRect; Image picture; Graphics g; private void InitilizePicture() { picture = Image.FromFile(Path.Combine(Environment.CurrentDirectory BG.jpg )); b.SetResolution(picture.HorizontalResolution picture.VerticalResolution); g = Graphics.FromImage(b); rect = new Rectangle(0 01600 900); // sourceRect = new Rectangle(new Point(0 0) new Size(picture.Width picture.Height)); sourceRect = new Rectangle(0 0 picture.Width picture.Height); g.DrawImage(picture rect sourceRect GraphicsUnit.Pixel); } private void Form1_MouseClick( object sender MouseEventArgs e) { Close(); } protected override void OnPaint(PaintEventArgs e) { e.Graphics.DrawImage(b rect sourceRect GraphicsUnit.Pixel); base .OnPaint(e); } } And you can add a property with set method so that you can change the image. On the other hand you can also add the BackgroundImage by using the Visual Studio. Best Regards
