Don't work for me with the last build :
the text on the page (the real one : not the watermark text) disapears from left to right when zooming ... try to set the zoom at 200 %

in fact it seems that it is a horizontal scrollbar problem ... try to zoom and play with Hscrolling

Hi，
for text watermark with chinese font (Simhei), your following shapesize calculaition code caused clipped watermark. The text cannot be fully displayed. Could you please help us? Thanks.
          Size sizeInPixels = TextRenderer.MeasureText(text, measureFont);
          shape.Size = new SizeF(Units.PixelsToDocumentsF(sizeInPixels.Width, richEditControl.DpiX), Units.PixelsToDoc

Hello,
The issue occurs depends on the value returned by the standard System.Window.Forms.TextRenderer.MeasureText method and doesn't rely on our products.
To resolve the issue, increase a shape size as follows:

[C#]
shape.TextBox.Document.EndUpdateCharacters(cp);shape.TextBox.HeightRule=TextBoxSizeRule.Auto;shape.RotationAngle=-45;SizesizeInPixels=TextRenderer.MeasureText(text,measureFont);shape.Size=newSizeF(Units.PixelsToDocumentsF(sizeInPixels.Width,richEditControl.DpiX)+ 10,Units.PixelsToDocumentsF(sizeInPixels.Height,richEditControl.DpiY));

Please try this solution and let me know your results.

Hi,
Really? Do you have check "Units.PixelsToDocumentsF"?

Hello,
I have researched the issue and came to the conclusion that the cause of the issue is rounding of the shape size on its rendering.
To resolve the issue, set the RichEditControl.LayoutUnit property to DocumentLayoutUnit.Document in the example's SetTextWatermark method without any other modifications.

Hi,
Set  RichEditControl.LayoutUnit doesn't work for me. The Text Water mark (Simhei)  are still clipped.
