DropShadowEffect for WPF Annotation Views

Post by gpbabu » Thu Aug 16, 2018 04:48 AM

Hello,

We are using DropShadowEffect for Wpf annotation views (WpfAnnotationView). All effects are visible in the annotation viewer. Is there anyway to burn annotations with DropShadowEffect onto image?

Thanks
Babu

Hello Yuri,

Please see the code. In Annotation viewer, annotation displays properly with a shadow. However, when it is burnt, it does not include the effect.

Thanks
Babu

// Set dropshadow effect for the annotation view.
rectangleAnnotationView.Effect = new DropShadowEffect
{
    ShadowDepth = 1,
    BlurRadius = 5,
    Direction = 270,
    Color = Color.FromArgb(255, 204, 204, 204),
};

Hello Babu,

Please try to use the RectangleAnnotationData.ShadowBrush property:

and let me know if you will have any question or problem.

Best regards, Alexander

Hi Alex,

We tried it. Rectangle with transparent fill color causes background shadow cover the fill area instead of showing the shadow for the outline. Also, it does not have a blur effect and only shows hard shadows. You may want to consider supporting in the product as it provides rich feature set for Vintasoft WPF controls.

Thanks
Babu

Hi Babu,

Please send us (to support@vintasoft.com) a simple working project, which shows the shadow effect you want to have. We will analyze your code and will try to provide you the best solution for your task.

Thanks Alex. We found an approach to burn annotations with effects by setting drawing visual effect to annotation view effect. It works very well. We could get all WPF effects into exported image.

Babu
