| Class | Description |
|---|---|
| PDFAtkinsonDitheringFilter | Defines a binarization filter that uses error diffusion dithering to convert grayscale data to black and white. |
| PDFBayerDitheringFilter | Defines a binarization filter that uses a matrix of threshold values to convert grayscale data to black and white. Gray values above the threshold are converted to white, gray values below the threshold are converted to black. |
| PDFBinarizationFilter | Defines the base class for binarization filters. Binarization filters are used when converting a PDF page to black and white. The page is initially rendered in grayscale and then the grayscale image is converted to black and white using a binarization filter. |
| PDFBurkesDitheringFilter | Defines a binarization filter that uses error diffusion dithering to convert grayscale data to black and white. |
| PDFErrorDiffusionDitheringFilter | Defines a binarization filter that uses error diffusion dithering to convert grayscale data to black and white. |
| PDFFloydSteinbergDitheringFilter | Defines a binarization filter that uses error diffusion dithering to convert grayscale data to black and white. |
| PDFJarvisJudiceNinkeDitheringFilter | Defines a binarization filter that uses error diffusion dithering to convert grayscale data to black and white. |
| PDFOrderedDitheringFilter | Defines a binarization filter that uses a matrix of threshold values to convert grayscale data to black and white. |
| PDFSierraDitheringFilter | Defines a binarization filter that uses error diffusion dithering to convert grayscale data to black and white. |
| PDFSierraLiteDitheringFilter | Defines a binarization filter that uses error diffusion dithering to convert grayscale data to black and white. |
| PDFSierraTwoRowDitheringFilter | Defines a binarization filter that uses error diffusion dithering to convert grayscale data to black and white. |
| PDFStuckiDitheringFilter | Defines a binarization filter that uses error diffusion dithering to convert grayscale data to black and white. |
| PDFThresholdFilter | Defines a binarization filter that uses a fixed threshold to convert grayscale data to black and white. Gray values above the threshold are converted to white, gray values below the threshold are converted to black. |
