Then your image should completely fill your window.Īnd you can always use and Uri to set the bitmapsource to the file on your system. If you set the image margin to 0 and remove the horizontal and vertical alignment.
And if image (from which you use the dispatcher) is also in the UI thread (what I guess it is since it is a UI object) then this wont make your application use multiple cores. If your pictures have different sizes, you can use the object-fit property in CSS to scale the images to fit within their container, while preserving their. The dispatcher is used to execute thing from other threads into the UI thread.
Background image stretch to fill code#
In the code behind you use the dispatcher to make things use multiple cores? This image tag is not in a canvas, it is in a grid. In the image tag in the XAML you said: Canvas.Left="-135" Canvas.Top="-32" Normal,īitmapSource bmpsrc = BitmapSource.Create(W, H, dpi, dpi, PixelFormats.Bgr24, null, m圜olorImage_IN, W * 3) Īnd in your XAML you name your image: imagePanel1 The first step is to dictate what size the image needs to occupy, and the second step is just scaling the image to that size. What else do I need to be doing? Any help with the code (see below) would be greatly appreciated.Ĭode I use to draw the image: byte m圜olorImage=// 256x256 RGB image loaded from disk
Note: Functionality used to be provided by BoxFit.fill, but the API has meanwhile changed such that BoxFit no longer provides this functionality. I am puzzled because I have set Stretch="Fill" in the XAML code. To make an Image fill its parent, simply wrap it into a FittedBox: FittedBox ( child: Image.asset ('foo.png'), fit: BoxFit.fill, ) FittedBox here will stretch the image to fill the space. Otherwise, if you are sticking with the Button idea, then you will need to force the scaling in the button to prevent the image from stretching. Allows passing CSS styles to the underlying image element. You need to set it as a Drawable to force the image aspect to the object. If no styles are applied to the image, the image will stretch to fit the container. Background images will always stretch to fit the view. image.ImageSource bmpsrc // if you can give the URL of the File Located on the Disk.
When my program displays an image which is smaller than the Image GUI object defined in XAML, it does not get stretched to fit as I would like it to.įor example a 256x256 image only occupies the upper left quadrant of my 512x512 Image GUI object. You should use ImageView if you don't want it to stretch. Instead of Image use Image Brush that will do the work for you.
