Class ImageBinarizationMethod

java.lang.Object

com.aspose.words.ImageBinarizationMethod

public class ImageBinarizationMethod
extends java.lang.Object

Specifies the method used to binarize image.

Examples:

Shows how to set the TIFF binarization error threshold when using the Floyd-Steinberg method to render a TIFF image.

 
 Document doc = new Document();
 DocumentBuilder builder = new DocumentBuilder(doc);

 builder.getParagraphFormat().setStyle(doc.getStyles().get("Heading 1"));
 builder.writeln("Hello world!");
 builder.insertImage(getImageDir() + "Logo.jpg");

 // When we save the document as a TIFF, we can pass a SaveOptions object to
 // adjust the dithering that Aspose.Words will apply when rendering this image.
 // The default value of the "ThresholdForFloydSteinbergDithering" property is 128.
 // Higher values tend to produce darker images.
 ImageSaveOptions options = new ImageSaveOptions(SaveFormat.TIFF);
 options.setTiffCompression(TiffCompression.CCITT_3);
 options.setTiffBinarizationMethod(ImageBinarizationMethod.FLOYD_STEINBERG_DITHERING);
 options.setThresholdForFloydSteinbergDithering((byte) 240);

 doc.save(getArtifactsDir() + "ImageSaveOptions.FloydSteinbergDithering.tiff", options);
