Why isn't the image in my image control clear?

问题

BitmapImage B = new BitmapImage();
B.BeginInit();
B.StreamSource = asm.GetManifestResourceStream("WpfApplication26.Back1.png");
B.EndInit();
image1.Source = B;

The size of the image (Back1.png) is 32*32, and I set the size of my image control to 32*32 and set the property "Scale" to "None".

回答1:

Try

RenderOptions.BitmapScalingMode="NearestNeighbor"

on the image control in xaml or

RenderOptions.SetBitmapScalingMode(image1, BitmapScalingMode.NearestNeighbor)

in code.

回答2:

Try SnapsToDevicePixels="True" on the image control.

回答3:

If you still want to clear the image, meaning, turning it to blank, just set the source to "null"

image1.Source = null;

This does not require a BitmapImage.

Sorry for the late reply...
