Transparent Annotations

Post by pvanderwest » Thu Oct 16, 2014 11:49 PM

I am placing a Text Highlight Annotation on a tif image. The background image show through just fine. When I use the highlight on another annotation (Text for example), I cannot see the text that is inside the annotation. The highlight seems to obscure the annotation behind it.

How can I make the annotation at the back visible through the front one?

Hello Pierre,

Yes, a highlight annotation obscures the annotation behind it if color blending is enabled (HighlightAnnotationData.BlendingMode != BlendingMode.Normal) in the highlight annotation. We will improve algorithm of highlight annotation in future version of SDK and the highlight annotation will not obscure the annotation behind it.

You can add request for this functionality here:

So if (blendingmode = normal) it will show through?

So if (blendingmode = normal) it will show through? Yes but the highlight annotation without blending (blendingmode = normal) is equal to the rectangle annotation with transparent background color. Is this suitable for you?

Best regards, Alexander
