writeablebitmap

BitmapImage bitmapImage = new BitmapImage(new Uri("arka_projects_as_logo.png", UriKind.Relative)); Image uiElement = new Image() { Source = bitmapImage }; ScaleTransform t = new ScaleTransform() { ScaleX = 0.2, ScaleY = 0.2 }; WriteableBitmap writeableBitmap = new WriteableBitmap(uiElement,t); I want to insert the result of this conversions (writeableBitmap) into System.Windows.Controls.Image. When I do this: Image arkaImage = new Image() { Source = writeableBitmap }; arkaImage isn't shown at all. What can be done to make it work? WriteableBitmap wb = .. using (MemoryStream ms = new

How do I calculate the required buffer size for the WriteableBitmap.WritePixels method? I am using the overload taking four parameters, the first is an Int32Rect, the next is a byte array containing the RGBA numbers for the colour, the third is the stride (which is the width of my writeable bitmap multiplied by the bits per pixel divided by 8), and the last is the buffer (referred to as the offset in Intellisense). I am getting the Buffer size is not sufficient runtime error in the below code: byte[] colourData = { 0, 0, 0, 0 }; var xCoordinate = 1; var yCoordinate = 1; var width = 2; var

Is there any way for converting WriteableBitmap to Bitmap in C# ? red_sky It's pretty straightforward, actually. Here's some code that should work. I haven't tested it and I'm writing it from the top of my head. private System.Drawing.Bitmap BitmapFromWriteableBitmap(WriteableBitmap writeBmp) { System.Drawing.Bitmap bmp; using (MemoryStream outStream = new MemoryStream()) { BitmapEncoder enc = new BmpBitmapEncoder(); enc.Frames.Add(BitmapFrame.Create((BitmapSource)writeBmp)); enc.Save(outStream); bmp = new System.Drawing.Bitmap(outStream); } return bmp; } The WriteableBitmap inherits from a

I am trying to render text on a bitmap in a Windows Phone 7 application. Code that looks more or less like the following would work fine when it's running on the main thread: public ImageSource RenderText(string text, double x, double y) { var canvas = new Canvas(); var textBlock = new TextBlock { Text = text }; canvas.Children.Add(textBloxk); Canvas.SetLeft(textBlock, x); Canvas.SetTop(textBlock, y); var bitmap = new WriteableBitmap(400, 400); bitmap.Render(canvas, null); bitmap.Invalidate(); return bitmap; } Now, since I have to render several images with more complex stuff, I would like to

How do I convert a WriteableBitmap object to a BitmapImage Object in WPF? This link covers silverlight, the process is not the same in WPF as the WriteableBitmap object does not have a SaveJpeg method. So my question is How do I convert a WriteableBitmap object to a BitmapImage Object in WPF? You can use one of the BitmapEncoders to save the WriteableBitmap frame to a new BitmapImage In this example we will use the PngBitmapEncoder but just choose the one that fits your situation. public BitmapImage ConvertWriteableBitmapToBitmapImage(WriteableBitmap wbm) { BitmapImage bmImage = new
