It creates files for use with a C compiler: for AVR, ARM, PIC, 8051 and ohter microcontrollers. There isn't any way to get the pixels out of a BitmapImage (short of rendering to a new bitmap with RenderTargetBitmap). Please read the sticky posts, especially the
How do you convert a byte array to a hexadecimal string, and vice versa? Call FlushAsync to cause the encoder to write the image data to the specified file. The answer you linked which created a WritableBitmap from a BitmapImage was for a Windows Phone Silverlight app, not a Windows Phone Runtime app. You can create a SoftwareBitmap from an existing WriteableBitmap by calling SoftwareBitmap.CreateCopyFromBuffer and supplying the PixelBuffer property of the WriteableBitmap to set the pixel data. I am doing some testing for a future project, in which I will be creating an image encryptor. giving access to its PixelBuffer. or an assembly reference?). I've already had the code for System.Drawing.Image, which worked fine and I tried to write a WPF analogue to it. Needed to convert Image.Source to a CanvasBitmap for a Win2D animation when neither the StorageFile nor uri is available. This tool uses 8 pixels per byte and will try to auto-convert your image to black & white. Is there a reason beyond protection from potential corruption to restrict a minister's ability to personally relieve and appoint civil servants? In windows store apps BitmapImage does not have a StreamSource property. You will need to keep track of the original source of the information and recreate the image in the WriteableBitmap from the original source. How can I convert a BitmapImage object to byte array in UWP ? so pixelArray[0],pixelArray[1],pixelArray[2] represent the RGB colours of the first pixel andpixelArray[3],pixelArray[4],pixelArray[5] the

You can use these arrays with programs for embedded systems with microcontrollers to output graphics on monochromatic LCD's or thermal printers (like Arduino with the Adafruit mini printer, which I needed this for). Create a new BitmapDecoder from the input stream. just to be safe, set the stream.Position = 0 before calling ReadBytes. {
