Canvas.FlattensTransparency Property
Whether the document being written forbids transparency (PDF/A-1, PDF/X-1a/X-3) and was asked to flatten it instead of
rejecting it (PdfGenerateConfig.TransparencyPolicy). The painter then renders what needs transparency as an
opaque bitmap.
public virtual bool FlattensTransparency { get; }
