是否有可以将PNG文件转换为PDF的.NET库? [英] Is there a .NET library that can convert PNG files to PDF?

问题描述

我有一个应用程序，需要即时转换PNG文件PDF.是否有一个现有的图书馆可以做到这一点?我希望PDF看起来与PNG完全一样-没有多余的边距，没有边框等.

I have an application where I need to convert PNG files PDF on the fly. Is there an existing library that will do this? I would like the PDF to look exactly like the PNG--no extra margins, no borders, etc.

我正在使用.NET 4.0.

I'm using .NET 4.0.

我尝试了iTextSharp，它的效果很好.这是我需要的基本代码.

I tried iTextSharp and it worked great. Here's the basic code to get what I needed.

using System;
using System.IO;
using iTextSharp.text;
using iTextSharp.text.pdf;

public class ITextPDFHelper
{
    public static void Main(string[] args)
    {
        ITextPDFHelper.CreatePDF("C:\\temp\test.pdf", "C:\\temp\test.png");
    }

    public static void CreatePDF(string fileToCreate, pngFileName)
    {
        Document doc = new Document();
        PdfWriter.GetInstance(doc, new FileStream(fileToCreate, FileMode.Create));
        doc.Open();
        Image png = Image.GetInstance(pngFileName);
        png.SetAbsolutePosition(0, 0);
        doc.Add(png);
        doc.Close();
    }//CreatePDF
}

推荐答案

您的意思是，一个包含单个页面的pdf文档?看看 ITextSharp

You mean, a pdf document containing a single page with your picture in it? Take a look at ITextSharp
