[Feature Request] ImageBrushEx in 15063

[h82258652]

In 15063, we can extend brush (by XamlCompositionBrushBase). How about create a ImageBrushEx?
I create my own here: https://github.com/h82258652/Projects/blob/dev/Libraries/SoftwareKobo.Controls.ImageEx.Uwp.15063/ImageBrushEx.cs

Interesting proposition, curious what others think. Could you create a uservoice for this and provide a bit more details?

Thanks. :)

Could probably be an extension of #1100 - that already creates an ImageBrush using the image cache internally for use with it's RoundedImage control

[hermitdave]

Yes @JohnnyWestlake precisely my thoughts on this. We should just wrap and expose the brush from RoundedImageEx.

[hermitdave]

Having looked at it further, I believe that in order to provide ImageEx Brush, we would need to ditch the shared code for ImageExBase. ImageExBrush would inherit from TileBrush and implement additional bits as needed.

Whilst this isn't difficult, I just want us to be on the same page.

What's the current status of this issue?

I don't know, it seems no one is handling this.

@Sergio0694 thoughts on how our existing ImageBlendBrush and the above would fit/work with your Pipeline brushes #3112?

[Sergio0694]

This is (somewhat) already possible with the pipeline API, like so:

<Rectangle>
    <Rectangle.Fill>
        <brushes:PipelineBrush>
            <brushes:PipelineBrush.Effects>
                <effects:ImageEffect
                    Uri="/Assets/SomeImage.png"
                    DPIMode="DisplayDpi"/>
            </brushes:PipelineBrush.Effects>
        </brushes:PipelineBrush>
    </Rectangle.Fill>
</Rectangle>

It would definitely be possible to reuse the same internal APIs and expose a some brush type with also more properties on top. Or better yet, add more options directly to that ImageEffect type, so that those will be usable from pipelines as well. I mean, we could also do both 😄

This is basically what the updated brushes like the AcrylicBrush, BackdropInvertBrush etc. are doing anyway, they're just creating a pipeline behind the scenes, wrapping that in a more user friendly class. But it's still the same backend in all cases.

@Sergio0694 I guess the things missing in the Pipeline Brushes and the ImageBlendBrush in the toolkit would be the Alignment properties from @h82258652's example?

Would it make sense to try and rebase ImageBlendBrush on top of an ImageEffect that provide that functionality and add these extra capabilities?
