Aspose::Slides::Effects::BiLevel::BiLevel ( float  threshold,
System::SharedPtr< IDOMObject parentImmediate 
)
protected

Bi-Level effect constructor.

//

Parameters
thresholdthe luminance threshold for the Bi-Level effect. // Values greater than or equal to the threshold are set to white. // Values lesser than the threshold are set to black. //

)
protectedvirtual

◆ Clone()

virtual System::SharedPtr<ImageTransformOperation> Aspose::Slides::Effects::BiLevel::Clone ( )
protectedvirtual

Returns effect object with new parent. In most cases returns the same object, but some can create a copy.

Returns

Implements Aspose::Slides::Effects::ImageTransformOperation.

◆ Equals()

virtual bool Aspose::Slides::Effects::BiLevel::Equals ( System::SharedPtr< System::Object obj)
virtual

Determines whether the specified BiLevel is equal to the current BiLevel.

Parameters
objThe BiLevel to compare.
Returns
true if objects are equal; otherwise, false.
