Examples
Shows how to select a bit-per-pixel rate with which to render a document to an 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");
ASSERT_LT(20000, MakeObject<System::IO::FileInfo>(ImageDir + u"Logo.jpg")->get_Length());
// When we save the document as an image, we can pass a SaveOptions object to
// select a pixel format for the image that the saving operation will generate.
// Various bit per pixel rates will affect the quality and file size of the generated image.
auto imageSaveOptions = MakeObject<ImageSaveOptions>(SaveFormat::Png);
imageSaveOptions->set_PixelFormat(imagePixelFormat);
// We can clone ImageSaveOptions instances.
ASPOSE_ASSERT_NE(imageSaveOptions, imageSaveOptions->Clone());
doc->Save(ArtifactsDir + u"ImageSaveOptions.PixelFormat.png", imageSaveOptions);
