Hello,

Thanks for your inquiry.
Regarding your needs, we recommend using a new method to convert HTML to PDF files, which relies on the Chrome browser and is more stable and effective than Qt plugins. Please refer to this tutorial for testing. If you have any questions, please feel free to write back.

Sincerely,

Okay does that support giving html as string rather than file location

[William.Zhang]

Hello,

Thanks for your reply.
Apologies, this way does not support directly passing an HTML String. However, as a solution, you can write the HTML String to a temporary file and pass the path of the temporary file to the ConvertToPdf method. After the conversion is complete, you can delete the temporary file. I have provided the complete code for your reference.

Code: Select all

string html = "<html><body><h1>Test</h1><img src=\"file:///D:/Projects/Test/test/jpg_44-2.jpg\"></body></html>";
string outputFile = @"HtmlToPDF.pdf";

// Specify the path to the Chrome plugin
string chromeLocation = "";

// Create an instance of the ChromeHtmlConverter class
ChromeHtmlConverter converter = new ChromeHtmlConverter(chromeLocation);

// Create an instance of the ConvertOptions class
ConvertOptions options = new ConvertOptions();

// Set the conversion timeout
options.Timeout = 10 * 3000;
// Set the paper size and margins for the PDF
options.PageSettings = new PageSettings()
{
    PaperWidth = 8.27,
    PaperHeight = 11.69,
    MarginTop = 0,
    MarginLeft = 0,
    MarginRight = 0,
    MarginBottom = 0
};

// Create a temporary file path with the .html extension
string tempFilePath = Path.ChangeExtension(Path.GetTempFileName(), ".html");
try
{
    // Write the HTML string to the temporary file
    File.WriteAllText(tempFilePath, html);

    // Convert the HTML to PDF
    converter.ConvertToPdf(tempFilePath, outputFile, options);
}
finally
{
    // Delete the temporary file
    File.Delete(tempFilePath);
}
