您正在使用Wkhtmltopdf使用c#,Asp.net从Html页面创建PDF。 PDF是平滑创建的,但是当我将图像添加到HTML时,它不会显示在PDF上。

<div id="Image" class="right" style="background:#333;height:15%;width:25%;">

  <img  width="100%" height="100%" src="../TempLogo/chafa.jpg" />

我使用过“file:/// E:/AMS/AMS/AMS.WEB/TempLogo/chafa.jpg”&amp; “src =”localhost:5822 / AMS.WEB / TempLogo / chafa.jpg“;但它也不起作用。我也尝试将版本从0.11更改为0.9,但也没有成功

     public static string HtmlToPdf(string pdfOutputLocation, string outputFilenamePrefix, string[] urls,
    string[] options = null,
    // string pdfHtmlToPdfExePath = "C:\\Program Files (x86)\\wkhtmltopdf\\wkhtmltopdf.exe")

   string pdfHtmlToPdfExePath = "C:\\Program Files\\wkhtmltopdf\\wkhtmltopdf.exe")
{
    string urlsSeparatedBySpaces = string.Empty;
    try
    {
        //Determine inputs
        if ((urls == null) || (urls.Length == 0))
            throw new Exception("No input URLs provided for HtmlToPdf");
        else
            urlsSeparatedBySpaces = String.Join(" ", urls); //Concatenate URLs

        string outputFolder = pdfOutputLocation;
        string outputFilename = outputFilenamePrefix + "_" + DateTime.Now.ToString("yyyy-MM-dd-hh-mm-ss-fff") + ".PDF"; // assemble destination PDF file name

        var p = new System.Diagnostics.Process()
        {
            StartInfo =
            {
                FileName = pdfHtmlToPdfExePath,
                Arguments = ((options == null) ? "" : String.Join(" ", options)) + " " + urlsSeparatedBySpaces + " " + outputFilename,
                UseShellExecute = false, // needs to be false in order to redirect output
                RedirectStandardOutput = true,
                RedirectStandardError = true,
                RedirectStandardInput = true, // redirect all 3, as it should be all 3 or none
                WorkingDirectory = HttpContext.Current.Server.MapPath(outputFolder),
                CreateNoWindow = true
            }
        };

        p.Start();

        // read the output here...
        var output = p.StandardOutput.ReadToEnd();
        var errorOutput = p.StandardError.ReadToEnd();

        // ...then wait n milliseconds for exit (as after exit, it can't read the output)
        p.WaitForExit(60000);

        // read the exit code, close process
        int returnCode = p.ExitCode;
        p.Close();

        // if 0 or 2, it worked so return path of pdf
        if ((returnCode == 0) || (returnCode == 2))
            return outputFolder + outputFilename;
        else
            throw new Exception(errorOutput);
    }
    catch (Exception exc)
    {
        throw new Exception("Problem generating PDF from HTML, URLs: " + urlsSeparatedBySpaces + ", outputFilename: " + outputFilenamePrefix, exc);
    }
}
