'Declaration

<BrowsableAttribute(False)>
Public Property SoftMask As PdfImageResource

[Browsable(False)]
public PdfImageResource SoftMask { get; set; }

[Browsable(False)]
public: __property PdfImageResource* get_SoftMask();
public: __property void set_SoftMask(
   PdfImageResource* value
);

[Browsable(False)]
public:
property PdfImageResource^ SoftMask {
   PdfImageResource^ get();
   void set(PdfImageResource^ value);
}

Remarks

The alpha source parameter in the graphics state determines whether the mask values are interpreted as shape or opacity. If present, this property overrides the current soft mask in the graphics state, as well as the image's Mask entry, if any. However, the other transparency-related graphics state parameters-blend mode and alpha constant-remain in effect.

Requirements

Target Platforms: .NET 8; .NET 7; .NET 6; .NET Framework 4.8, 4.7, 4.6, 4.5, 4.0, 3.5
