ImageSaveOptions::get_ThresholdForFloydSteinbergDithering method

Gets or sets the threshold that determines the value of the binarization error in the Floyd-Steinberg method. when ImageBinarizationMethod is FloydSteinbergDithering.

uint8_t Aspose::Words::Saving::ImageSaveOptions::get_ThresholdForFloydSteinbergDithering() const

Remarks

The default value is 128.

Examples

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

auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>(doc);

builder->get_ParagraphFormat()->set_Style(doc->get_Styles()->idx_get(u"Heading 1"));
builder->Writeln(u"Hello world!");
builder->InsertImage(get_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 = System::MakeObject<Aspose::Words::Saving::ImageSaveOptions>(Aspose::Words::SaveFormat::Tiff);
options->set_TiffCompression(Aspose::Words::Saving::TiffCompression::Ccitt3);
options->set_TiffBinarizationMethod(Aspose::Words::Saving::ImageBinarizationMethod::FloydSteinbergDithering);
options->set_ThresholdForFloydSteinbergDithering(240);

doc->Save(get_ArtifactsDir() + u"ImageSaveOptions.FloydSteinbergDithering.tiff", options);
