I have some Text as part of my Diagram Shapes but text values some times get rasterized and loose their clearances and their qualities.

 

Is there anyway to resolve this issue ?

Hello Bruno,

You can try setting UseLayoutRounding property on the root element to true and see if this will solve the issue. If not, please give us more detailed information about your scenario - e.g. it is reproducible after resizing of the shape, in which cases, etc.

I hope this information helps.

Hello Milena,

I have tried to set the UseLayoutRounding to true on the root but nothing changed. The issue is when Diagram is not in its max zoom level the Text doesn't seem to be rendered vectorial. (Look at attached images)

Thanks,

Ali

Hi Bruno,

Thank you for the pictures provided.

I think that this issue is not connected to the RadDiagram control, but to the implementation of the Text rendering in WPF. You can try to experiment with TextOptions class and TextFormattingMode and TextRenderingMode properties to avoid this blurry effect of the text. You can also take a look at this post where you can find examples of how to control the text rendering. 

I hope this information helps.

Thanks Milena,

 

Setting TextOptions.TextFormattingMode="Ideal" resolved the issue.
