Windows Phone 8.1 中的 PDF

Question

因为 PdfDocument class 仅在 Windows 8.1 中可用，所以在 Windows phone 8.1（windows 运行时）中可以使用一些东西用于在我的应用程序中呈现 pdf 文件？

编辑

MuPdf 太棒了！但是为了让它在 Windows Phone 项目中工作，我必须手动编辑 .csproj

我不得不添加这段代码：

<Reference Include="MuPDFWinRT, Version=255.255.255.255, Culture=neutral, processorArchitecture=MSIL" Condition="'$(Platform)'=='x86'">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\MuPDF\x86\MuPDFWinRT.winmd</HintPath>
</Reference>
<Reference Include="MuPDFWinRT, Version=255.255.255.255, Culture=neutral, processorArchitecture=MSIL" Condition="'$(Platform)'=='ARM' ">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\MuPDF\ARM\MuPDFWinRT.winmd</HintPath>
</Reference>

这是一个用法示例：

IBuffer readBuffer = pdf.AsBuffer();

var pdfDocument = Document.Create(readBuffer, DocumentType.PDF, (int)Windows.Graphics.Display.DisplayInformation.GetForCurrentView().LogicalDpi);

List<WriteableBitmap> imageList = new List<WriteableBitmap>();

for (int i = 0; i < pdfDocument.PageCount; i++)
{
    var size = pdfDocument.GetPageSize(i);
    var width = size.X;
    var height = size.Y;

    var image = new WriteableBitmap(width, height);
    IBuffer buf = new Buffer(image.PixelBuffer.Capacity);
    buf.Length = image.PixelBuffer.Length;

    pdfDocument.DrawPage(i, buf, 0, 0, width, height, false);

    using (var stream = buf.AsStream())
    {
        await stream.CopyToAsync(image.PixelBuffer.AsStream());
    }

    imageList.Add(image);
}

您可以试试 MuPDF：https://github.com/MishaUliutin/MuPDF.WinRT .

MuPDF.WinRT is a lightweight PDF, XPS and CBZ viewer and parser/rendering WinRT component.

如果这不起作用.. 请同时查看此库： http://www.xfiniumpdf.com/xfinium-pdf-downloads.html
