こんにちは、Wkhtmltopdf を使用して、C#、Asp.net を使用して Html ページから PDF を作成しています。PDF は問題なく作成できるのですが、HTML に画像を追加すると PDF に表示されません。
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);
}
}
これは、画像を表示するための私の HTML コード領域です。
