Detailed Description
Class is used to optimize bitmap images.
Constructor & Destructor Documentation
◆ BitmapCompressor() [1/2]
|
inline |
Creates a new instance of processor.
Creates a new instance of processor. By default iText.Pdfoptimizer.Handlers.Imagequality.Processors.Scaling.AverageCalculationAlgorithm is used for scaling.
- Parameters
-
scaling is a scaling coefficient, must be in range [0., 1.] compression is a compression coefficient, must be in range [0., 1.]
◆ BitmapCompressor() [2/2]
|
inline |
Creates a new instance of processor.
- Parameters
-
scaling is a scaling coefficient, must be in range [0., 1.] algorithm is a scaling algorithm compression is a compression coefficient, must be in range [0., 1.]
