Constructor Details

BitmapScalingProcessor

             public BitmapScalingProcessor
             (double scaling)
            

Creates an instance of bitmap image processor. AverageCalculationAlgorithm will be used as scaling algorithm.

Parameters:

scaling - is a scaling coefficient

BitmapScalingProcessor

             public BitmapScalingProcessor
             (double scaling, IScalingAlgorithm algorithm)
            

Creates an instance of bitmap image processor.

Parameters:

scaling - is a scaling coefficient

algorithm - is a scaling algorithm

Method Details

processImage

             public com.itextpdf.kernel.pdf.xobject.PdfImageXObject processImage
             (com.itextpdf.kernel.pdf.xobject.PdfImageXObject objectToProcess, OptimizationSession session)
            

Scales a bitmap image presented as PdfImageXObject.

Specified by:

processImage in interface IImageProcessor

Parameters:

objectToProcess - is a PdfImageXObject representing the image

session - is an auxiliary object used to support share data between stages of optimization process

Returns:

processed image if processing can be performed and the same instance otherwise
