BitmapImagePixels iText.Pdfoptimizer.Handlers.Imagequality.Processors.Scaling.IScalingAlgorithm.Scale	(	BitmapImagePixels	original,
		double	scaling
	)

Scales a bitmap image.

Parameters

original	is an image to scale presented as iText.Pdfoptimizer.Handlers.Util.BitmapImagePixels
scaling	is a scaling coefficient. Should be in (0, 1] range

Returns

scaled image

Implemented in iText.Pdfoptimizer.Handlers.Imagequality.Processors.Scaling.AverageCalculationAlgorithm, and iText.Pdfoptimizer.Handlers.Imagequality.Processors.Scaling.DroppingAlgorithm.
