I would like to know if the LinearGradientBrush supports StartPoint, EndPoint and GradientStops - and if not if there are plans for thenm to be supported in the future.  Many Thanks

Hi Paul,

Yes, it is possible. Please have a look at the GdiPlusX samples "Gradient3.scx" and "Gradients.scx".

Many Thanks Cesar - can I just say that it would be helpful if the download page for the latest version had the link to the samples download on it ...

Hi Paul,

I truly don't know what happened with that release. Notice that the DEMO version that I pointed you is not the most recent.

The latest sources are version 1.20 , and the DEMO version brings version 1.10. Just take care to use the latest sources. We definitely have to create a new release for the DEMOS, thanks for bringing this to our attention.

In the following scenario I want to get the RGB value for any intermediate point  (e.g. 0.25 or 0.75).  Is this possible ?

    cb = .Drawing2d.ColorBlend.New(3)
    cb.Positions[1] = 0
    cb.Positions[1] = 0.5
    cb.Positions[1] = 1.0
    cb.Colors = .Color.NewArray(.Color.Red,  .Color.Yellow, .Color.Blue)
    br.InterpolationColors = cb

Many thanks

    cb.Positions[1] = 0
    cb.Positions[2] = 0.5
    cb.Positions[3] = 1

I truly don't know a simple way

If you really need it, you can use the GetPixel function from the xfcBitmap class to get the color.
