【Aspose.Words for .NET使用教程】将word和图像转换为PDF

Aspose.Words无需Microsoft Word也可在任何平台上满足Word文档的一切操作需求。本文将与大家分享如何将word和图像转换为PDF。

将Microsoft Word文档转换为PDF

要将Microsoft Word文档转换为PDF，只需调用Document.Save方法并将文件的扩展名指定为“.PDF”。下面的代码示例使用默认选项将整个文档从DOC转换为PDF。你可以从此处下载此示例的模板文件。

// For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_QuickStart();
// Load the document from disk.
Document doc = new Document(dataDir + "Template.doc");
dataDir = dataDir + "Template_out.pdf";
// Save the document in PDF format.
doc.Save(dataDir);

将图像档转换为PDF

这里介绍如何使用Aspose.Words从图像创建PDF文档。虽然将图像转换为PDF不是Aspose.Words的主要特征，但此示例显示了Aspose.Words十分简洁易用。要使此代码有效，你需要将Aspose.Words和System.Drawing的参考文件添加到项目中。下面的代码允许转换单帧图像，如JPEG，PNG，BMP，EMF或WMF，以及多帧TIF图像和GIF到PDF。

// For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_LoadingAndSaving();
ConvertImageToPdf(dataDir + "Test.jpg", dataDir + "TestJpg_out.pdf");
ConvertImageToPdf(dataDir + "Test.png", dataDir + "TestPng_out.pdf");
ConvertImageToPdf(dataDir + "Test.wmf", dataDir + "TestWmf_out.pdf");
ConvertImageToPdf(dataDir + "Test.tiff", dataDir + "TestTif_out.pdf");
ConvertImageToPdf(dataDir + "Test.gif", dataDir + "TestGif_out.pdf");

ConvertImageToPdf方法

// For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-.NET
// Create Document and DocumentBuilder. 
// The builder makes it simple to add content to the document.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Read the image from file, ensure it is disposed.
using (Image image = Image.FromFile(inputFileName))
{
 // Find which dimension the frames in this image represent. For example 
 // The frames of a BMP or TIFF are "page dimension" whereas frames of a GIF image are "time dimension". 
 FrameDimension dimension = new FrameDimension(image.FrameDimensionsList[0]);
 // Get the number of frames in the image.
 int framesCount = image.GetFrameCount(dimension);
 // Loop through all frames.
 for (int frameIdx = 0; frameIdx < framesCount; frameIdx++)
 {
 // Insert a section break before each new page, in case of a multi-frame TIFF.
 if (frameIdx != 0)
 builder.InsertBreak(BreakType.SectionBreakNewPage);
 // Select active frame.
 image.SelectActiveFrame(dimension, frameIdx);
 // We want the size of the page to be the same as the size of the image.
 // Convert pixels to points to size the page to the actual image size.
 PageSetup ps = builder.PageSetup;
 ps.PageWidth = ConvertUtil.PixelToPoint(image.Width, image.HorizontalResolution);
 ps.PageHeight = ConvertUtil.PixelToPoint(image.Height, image.VerticalResolution);
 // Insert the image into the document and position it at the top left corner of the page.
 builder.InsertImage(
 image,
 RelativeHorizontalPosition.Page,
 0,
 RelativeVerticalPosition.Page,
 0,
 ps.PageWidth,
 ps.PageHeight,
 WrapType.None);
 }
}
// Save the document to PDF.
doc.Save(outputFileName);
