<div class="markdown level1 remarks"><p>
This method creates a visual representation of the 3D content that is displayed when the 3D annotation
is not activated. Since DsPdf cannot automatically generate previews for 3D content, you must provide
a preview image generated by a third-party tool or rendered separately.
</p>
<p>
The provided image is stretched to fill the annotation's bounds (<a class="xref" href="GrapeCity.Documents.Pdf.Annotations.AnnotationBase.Rect.html#GrapeCity_Documents_Pdf_Annotations_AnnotationBase_Rect">Rect</a>).
The appearance stream is stored as the normal default appearance of the annotation.
