近月,针对Aspose.XPS和Aspose.EPS做了一些改动,将其合并成Aspose.Page,同样可以使用现有许可证访问这两种产品的所有功能。
Aspose.Page (点击下载)是集成On-Premise API,以.NET和Java应用程序中创建,操作或转换XPS,EPS和PS文件。或使用免费应用程序即时查看或转换文件。
功能亮点
Aspose.Page允许文档转换。例如,您可以将XPS转换为PDF。让我们试试转换的例子。
.NET
//文档目录的路径。 string dataDir = RunExamples.GetDataDir_WorkingWithDocumentConversion(); //初始化PDF输出流 using (System.IO.Stream pdfStream = System.IO.File.Open(dataDir + "input.xps", System.IO.FileMode.Create, System.IO.FileAccess.Write)) //初始化XPS输入流 using (System.IO.Stream xpsStream = System.IO.File.Open(dataDir + "XPStoPDF.pdf", System.IO.FileMode.Open, System.IO.FileAccess.Read)) { //从流中加载XPS文档 XpsDocument document = new XpsDocument(xpsStream, new XpsLoadOptions()); //或直接从文件加载XPS文档。那么不需要xpsStream。 // XpsDocument document = new XpsDocument(inputFileName, new XpsLoadOptions()); //使用必要参数初始化选项对象。 Aspose.Page.Xps.Presentation.Pdf.PdfSaveOptions options = new Aspose.Page.Xps.Presentation.Pdf.PdfSaveOptions() { JpegQualityLevel = 100, ImageCompression = Aspose.Page.Xps.Presentation.Pdf.PdfImageCompression.Jpeg, TextCompression = Aspose.Page.Xps.Presentation.Pdf.PdfTextCompression.Flate, PageNumbers = new int[] { 1, 2, 6 } }; //为PDF格式创建渲染设备 Aspose.Page.Xps.Presentation.Pdf.PdfDevice device = new Aspose.Page.Xps.Presentation.Pdf.PdfDevice(pdfStream); document.Save(device, options); }
Java
// 文档目录的路径。 String dataDir = Utils.getDataDir(); //初始化PDF输出流 FileOutputStream pdfStream = new FileOutputStream(dataDir + "XPStoPDF.pdf"); //加载XPS文档 XpsDocument document = new XpsDocument(dataDir + "input.xps"); //使用必要参数初始化选项对象。 com.aspose.xps.rendering.PdfSaveOptions options = new com.aspose.xps.rendering.PdfSaveOptions(); options.setJpegQualityLevel(100); options.setImageCompression(com.aspose.xps.rendering.PdfImageCompression.Jpeg); options.setTextCompression(com.aspose.xps.rendering.PdfTextCompression.Flate); options.setPageNumbers(new int[] { 1, 2, 6 }); //为PDF格式创建渲染设备 com.aspose.xps.rendering.PdfDevice device = new com.aspose.xps.rendering.PdfDevice(pdfStream); document.save(device, options);
