Examples

Renders a page of a Word document into an image with transparent or colored background.

auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);

builder->get_Font()->set_Name(u"Times New Roman");
builder->get_Font()->set_Size(24);
builder->Writeln(u"Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.");

builder->InsertImage(ImageDir + u"Logo.jpg");

// Create an "ImageSaveOptions" object which we can pass to the document's "Save" method
// to modify the way in which that method renders the document into an image.
auto imgOptions = MakeObject<ImageSaveOptions>(SaveFormat::Png);

// Set the "PaperColor" property to a transparent color to apply a transparent
// background to the document while rendering it to an image.
imgOptions->set_PaperColor(System::Drawing::Color::get_Transparent());

doc->Save(ArtifactsDir + u"ImageSaveOptions.PaperColor.Transparent.png", imgOptions);

// Set the "PaperColor" property to an opaque color to apply that color
// as the background of the document as we render it to an image.
imgOptions->set_PaperColor(System::Drawing::Color::get_LightCoral());

doc->Save(ArtifactsDir + u"ImageSaveOptions.PaperColor.LightCoral.png", imgOptions);

Shows how to configure compression while saving a document as a JPEG.

auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);
builder->InsertImage(ImageDir + u"Logo.jpg");

// Create an "ImageSaveOptions" object which we can pass to the document's "Save" method
// to modify the way in which that method renders the document into an image.
auto imageOptions = MakeObject<ImageSaveOptions>(SaveFormat::Jpeg);

// Set the "JpegQuality" property to "10" to use stronger compression when rendering the document.
// This will reduce the file size of the document, but the image will display more prominent compression artifacts.
imageOptions->set_JpegQuality(10);

doc->Save(ArtifactsDir + u"ImageSaveOptions.JpegQuality.HighCompression.jpg", imageOptions);

ASSERT_GE(20000, MakeObject<System::IO::FileInfo>(ArtifactsDir + u"ImageSaveOptions.JpegQuality.HighCompression.jpg")->get_Length());

// Set the "JpegQuality" property to "100" to use weaker compression when rending the document.
// This will improve the quality of the image at the cost of an increased file size.
imageOptions->set_JpegQuality(100);

doc->Save(ArtifactsDir + u"ImageSaveOptions.JpegQuality.HighQuality.jpg", imageOptions);

ASSERT_LT(60000, MakeObject<System::IO::FileInfo>(ArtifactsDir + u"ImageSaveOptions.JpegQuality.HighQuality.jpg")->get_Length());

Shows how to specify a resolution while rendering a document to PNG.

auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);

builder->get_Font()->set_Name(u"Times New Roman");
builder->get_Font()->set_Size(24);
builder->Writeln(u"Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.");

// Create an "ImageSaveOptions" object which we can pass to the document's "Save" method
// to modify the way in which that method renders the document into an image.
auto options = MakeObject<ImageSaveOptions>(SaveFormat::Png);

// Set the "Resolution" property to "72" to render the document in 72dpi.
options->set_Resolution(72.0f);

doc->Save(ArtifactsDir + u"ImageSaveOptions.Resolution.72dpi.png", options);

ASSERT_GE(120000, MakeObject<System::IO::FileInfo>(ArtifactsDir + u"ImageSaveOptions.Resolution.72dpi.png")->get_Length());

// Set the "Resolution" property to "300" to render the document in 300dpi.
