Replacement of System.drawing in developing window

Question

Can any one tell me what is the replacement of System.Drawing in developing windows 8 apps. I tried System.Drawing but it is not supported by windows 8 apps. I have to use Image.FromFile() but it is showing error in windows 8. It is working fine in console application.

Answer 1

Perhaps this article from MSDN might help you out: XAML vector-based drawing sample.

The sample covers:

• Drawing basic shapes using the Rectangle , Line , Ellipse , and Polygon classes.
• Applying Stroke and Fill values to define the appearance of the outline and interior of the shape.
• Applying a LinearGradientBrush fill. Clipping elements by setting the Clip property.
• Drawing complex, compound shapes using Path elements that contain various shapes, figures, and Bezier curves.

Edit:

Instead of the System.Drawing namespace, for Windows 8 there is the Windows.Graphics.Imaging namespace. If you follow the link you'll find several samples/articles explaining how to process image files, how to encode (file from image) or decode (image from file) or how to edit an image.

Hope this helps you out further! :)

I used the namespace Windows.Graphics.Imaging and tried to convert my tiff image into jpeg but it is not working. pls check the following code and tell me what i am doing wrong in the code.

                        Image myImage = new Image();
                        var stream = await image.OpenAsync(Windows.Storage.FileAccessMode.Read);
                        var bitmapImage = new Windows.UI.Xaml.Media.Imaging.BitmapImage();
                        await bitmapImage.SetSourceAsync(stream);
                        myImage.Source = bitmapImage;
                        var decoder = await Windows.Graphics.Imaging.BitmapDecoder.CreateAsync(stream);
