Alfa channel doesn't work

[burikus]

Hi!
I try to use SixLabors library, but got a problem.
var color = Color.FromRgba(255, 255, 255, 32);
var brush = new SolidBrush(color);
Here, no matter which Alfa value is set (0-255) - Always solid color.
Is it a bug or I do smth wrong ?

(On the other hand, system.drawing
var color = Color.FromArgb(32, 255, 255, 255); works perfect.)

You’re using a pixel format that doesn’t contain an alpha component. Use the generic API and Rgba32 or similar

Thank you/ I changed to
Image.Load<Rgba32>
and set
Color.FromPixel<Rgba32>(new Rgba32(255, 255, 255, 32));
now it works.
