Add Image inside XPS Documents

Add Image

Aspose.Page for C++ API lets you create/read XPS documents and add image to it. This can be done by creating XpsMatrix and XpsImageBrush to add the image to the XPS file. In order to add an image to XPS document, use the following steps.

1. Create an object of XpsDocument class
2. Create XpsPath object with defined Path Geometry
3. Set Render Transformation for the path using set_RenderTransform
4. Fill path with creared image brush using set_Fill
5. Save the document to disc using the Save method

For complete examples and data files, please go to https://github.com/aspose-page/Aspose.Page-for-C
// Create new XPS Document
System::SharedPtr<XpsDocument> doc = System::MakeObject<XpsDocument>();
// Add Image
System::SharedPtr<XpsPath> path = doc->AddPath(doc->CreatePathGeometry(u"M 30,20 l 258.24,0 0,56.64 -258.24,0 Z"));
//Creating a matrix is optional, it can be used for proper positioning
path->set_RenderTransform(doc->CreateMatrix(0.7f, 0.f, 0.f, 0.7f, 0.f, 20.f));
//Create Image Brush
path->set_Fill(doc->CreateImageBrush(dataDir() + u"QL_logo_color.tif", System::Drawing::RectangleF(0.f, 0.f, 258.24f, 56.64f), System::Drawing::RectangleF(50.f, 20.f, 193.68f, 42.48f)));
// Save resultant XPS document
doc->Save(outDir() + u"AddImage_out.xps");

Add Tiled Image

The solution offers  XpsPath Class, with which you can add image on XPS document. After creating a Matrix and an ImageBrush as above, then specify  XpsTileMode.Tile mode. You can set Opacity value from 0 to 1 for the ImageBrush. Then save document. Following code snippet shows complete functionality to add tiled image on an XPS document:

For complete examples and data files, please go to https://github.com/aspose-page/Aspose.Page-for-C
// Create new XPS Document
System::SharedPtr<XpsDocument> doc = System::MakeObject<XpsDocument>();
// Tile image
// ImageBrush filled rectangle in the right top bellow
System::SharedPtr<XpsPath> path = doc->AddPath(doc->CreatePathGeometry(u"M 10,160 L 228,160 228,305 10,305"));
path->set_Fill(doc->CreateImageBrush(dataDir() + u"R08LN_NN.jpg", System::Drawing::RectangleF(0.f, 0.f, 128.f, 96.f), System::Drawing::RectangleF(0.f, 0.f, 64.f, 48.f)));
(System::DynamicCast<Aspose::Page::Xps::XpsModel::XpsImageBrush>(path->get_Fill()))->set_TileMode(Aspose::Page::Xps::XpsModel::XpsTileMode::Tile);
path->get_Fill()->set_Opacity(0.5f);
// Save resultant XPS document
doc->Save(outDir() + u"AddTiledImage_out.xps");
