Why RenderOptions.BitmapInterpolationMode is not available in xaml?

[J0nathan550]

Why RenderOptions.BitmapInterpolationMode is not available in xaml why it is hidden but available in the source code?

[stevemonaco]

It is available, but IntelliSense won't give any autocomplete.

<Image Source="..." RenderOptions.BitmapInterpolationMode="None" />

[J0nathan550]

It doesn't compile.
Actually it does compile, but it doesn't work for image brush.

Really? I cannot complie and found the BitmapInterpolationMode property is no longer avalible since last year(0442c3b#diff-30146ad647035810a03aa11110124ad0fadea7511ded3ed0c037f2e2c3fe26f3L10)
Did you use 0.10? I am using the 11.1.3

[stevemonaco]

RenderOptions.BitmapInterpolationMode still works in 11.1.3. You won't see it pop up in IntelliSense (or in Rider).

[yll690]

Okey, after some attempts, I found it can only set directly to the control instead of setting in styles now.

[stevemonaco]

It's a normal property now instead of a StyledProperty, so you can't set via style anymore.

It is available, but IntelliSense won't give any autocomplete.

<Image Source="..." RenderOptions.BitmapInterpolationMode="None" />

Actually, it does work. But only for the Image. It doesn't work for ImageBrush.

[stevemonaco]

I think it's only valid on Visuals. Which Controls are and Brushes aren't. Otherwise, show more code of what you're trying to do.

[J0nathan550]

Trying to increase quality of image brush.

[workgroupengineering]

there is a pr but it was not merged

[stevemonaco]

If you set RenderOptions.BitmapInterpolationMode="HighQuality" on the UserControl, does it affect the brush? There was some talk about allowing overriding the defaults awhile back, but that hasn't been implemented. It's a bit hard to track down.

Alternatively, use layer stacking instead of ImageBrush:

<UserControl ...>
  <Panel>
    <Image Source="/Assets/background.jpg" Stretch="UniformToFill" RenderOptions.BitmapInterpolationMode="HighQuality" />
    <TextBlock Text="Your Stacked Content Here" />
  </Panel>
</UserControl>
