Question

I am trying to load a image from Embedded Resource to an Image instance. The problem is the size of the image is always 0.

Here is the code snippet:

Image image = new Image();
ImageSource img = new System.Windows.Media.Imaging.BitmapImage(new Uri("/Images/marker.png", UriKind.Relative));
image.SetValue(Image.SourceProperty, img);


System.Diagnostics.Debug.WriteLine("output 1 = " + image.DesiredSize.Width); // return 0
System.Diagnostics.Debug.WriteLine("output 2 = " + image.ActualWidth); // return 0

I have to know the size of the image before it rendered on the screen, because I need to offset the image depending on the size of it.

Thank you

Update:
Thanks Silvermind

I answered my own question with sample code

Answer 1

Thanks Silvermind. He suggested to use CreateOptions.

Finally, I found a solution:

Image image = new Image();

Uri uri = new Uri("/Images/marker_stop.png", UriKind.Relative);
BitmapImage bi = new BitmapImage(uri);
bi.CreateOptions = BitmapCreateOptions.IgnoreImageCache;

image.Source = bi;
System.Diagnostics.Debug.WriteLine("************************************* in image.ActualWidth " + ", " + bi.PixelWidth); // return 30
