如何在pdfsharp.dll的帮助下在pdf文件中添加图像 [英] How to add a image in pdf file with the help of pdfsharp.dll

问题描述

我正在开发Windows应用程序以在pdfsharp.dll文件的帮助下生成pdf。我想用pdf生成图像。在添加图像时，我收到了一个错误，例如

不支持给定路径的格式。



我的代码是

XImage img = XImage.FromFile（C：/Users/D3/Desktop/img1.jpg）;

I'm developing windows application to generate pdf with the help of pdfsharp.dll file.I want to generate a image in pdf.While adding the image,i got an error like
The given path's format is not supported.

My code is
XImage img = XImage.FromFile("‪C:/Users/D3/Desktop/img1.jpg");

推荐答案

string pdfpath = Server.MapPath（PDFs）;

string imagepath = Server.MapPath（Images）;

文档doc = new Document（）;

try

{

PdfWriter.GetInstance（doc，new FileStream（pdfpath +/ Image.pdf，FileMode.Create））;

doc.Open（）;



doc.Add（新段落（GIF））;

图像gif = Image.GetInstance（imagepath +/ mikesdotnetting。 gif）;

doc.Add（gif）;

}

catch（Exception ex）

{

//记录错误;

}

最后

{

doc。 C lost（）;

}

string pdfpath = Server.MapPath("PDFs");
string imagepath = Server.MapPath("Images");
Document doc = new Document();
try
{
PdfWriter.GetInstance(doc, new FileStream(pdfpath + "/Images.pdf", FileMode.Create));
doc.Open();

doc.Add(new Paragraph("GIF"));
Image gif = Image.GetInstance(imagepath + "/mikesdotnetting.gif");
doc.Add(gif);
}
catch (Exception ex)
{
//Log error;
}
finally
{
doc.Close();
}

此代码适用于TIFF文件！

您的解决方案可能是这样的：

This code works well with TIFF files!
Your solution can be something like this:

string name = @"path\of\your\image";
string dest = @"path\of\destination";
// each source file separate
PdfSharp.Pdf.PdfDocument doc = new PdfSharp.Pdf.PdfDocument();

XImage img = XImage.FromFile(name);
img.Interpolate = false;
int width = img.PixelWidth;
int height = img.PixelHeight;
PdfSharp.Pdf.PdfPage page = new PdfSharp.Pdf.PdfPage
{
    Width = width,
    Height = height
};
doc.Pages.Add(page);
XGraphics xgr = XGraphics.FromPdfPage(doc.Pages[0]);

xgr.DrawImage(img, 0, 0, width, height);
img.Dispose();
xgr.Dispose();
//  save to destination file
FileInfo fi = new FileInfo(name);

doc.Save(dest + "\\" + name + ".PDF");
doc.Dispose();
