opacity is ignored for Image background

[ialbert-AUT]

Description

Background is not transparent and should be grayish:

<Image Source="dotnet_bot.png" BackgroundColor="Black"
			Opacity="0.5"
			Margin="20, 10, 0, 0"
			HorizontalOptions="Start" / >

Also Hot Reload issue: start debugging and adding the Opacity property later doesn't change the rendering. If I add the Opacity before starting and change the values it honours them fine.

Steps to Reproduce

<Image Source="dotnet_bot.png" BackgroundColor="Black"
			Opacity="0.5"
			Margin="20, 10, 0, 0"
			HorizontalOptions="Start" / >

hi, the code is there but somehow it gets hidden. Strange.

ahh, the "/>" confuses the engine.

Ah gotcha! Haha yeah if you wrap it in the code formatting it should prevent that from happening. Edited your original post now to do that so you might want to use that next time :) thanks!

Repro on Android emulator. But, just curious, does opacity property affect both image and background?

hm. Opacity is a property of VisualElement, so generic.
I could use the alpha channel of the BackgroundColor / Brush for opacity.
In that case this is not a bug! :)
