SharpDX Color from RGB

[habibalex]

In NT7 I used the follow to set the transparency and color for my brushes, I can't find any documentation on how to do the same for a SharpDX.Direct2D1.Brush

What would be the equivalent for a SharpDX Brush using the NT7 code below?

Color grayColor = Color.FromArgb(255,grayScale, grayScale, grayScale);

Edit: Found this after a lot of searching

Brush grayColor = new SolidColorBrush(Color.FromArgb(255,grayScale, grayScale, grayScale));

grayColor.ToDxBrush(RenderTarget)

Hi,

I had trouble when I didn't freeze brushes I created:

You should probably do the same. It would be something like this:

Brush grayColor = new SolidColorBrush(Color.FromArgb(255,grayScale, grayScale, grayScale));

grayColor.Freeze();

grayColor.ToDxBrush(RenderTarget)

This is due to the multiple threads NT8 uses...

So any brushes that I do not change after i set the color, it makes sense to use the Freeze() method, but what about in situations like in a for loop where I change the grayScale once per loop iteration?

Hello habibalex,

In this instance you would not freeze the brush. In general I believe WPF will create a clone of the brush in a frozen state to render the content if you do not freeze the brush yourself. Freezing the brush yourself prevents this copying, but obviously you would not be able to do that if you were dynamically modifying its values.

Please let me know if I may be of further assistance.
