Examples
Shows how to set the TIFF binarization error threshold when using the Floyd-Steinberg method to render a TIFF image.
auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);
builder->get_ParagraphFormat()->set_Style(doc->get_Styles()->idx_get(u"Heading 1"));
builder->Writeln(u"Hello world!");
builder->InsertImage(ImageDir + u"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.
auto options = MakeObject<ImageSaveOptions>(SaveFormat::Tiff);
options->set_TiffCompression(TiffCompression::Ccitt3);
options->set_TiffBinarizationMethod(ImageBinarizationMethod::FloydSteinbergDithering);
options->set_ThresholdForFloydSteinbergDithering(240);
doc->Save(ArtifactsDir + u"ImageSaveOptions.FloydSteinbergDithering.tiff", options);
