HTML to PDF Conversion

Postby mbyrne » Wed May 01, 2013 4:43 pm

Greetings, my company is actively evaluating the purchase of Spire.Office for .NET Site Enterprise Subscription.

We are looking at the capabilities for generating a PDF from HTML, and have come up with a few questions.

1) We are currently using the PdfDocument LoadFromHTML method. When I use the following code, the PDF generated from www.google.com contains scroll bars. Does the process of converting to HTML depend on loading a web browser / rendering engine?

2) Do you have documentation or suggestions for formatting the HTML / CSS to avoid scroll bars? Is there a suggested width?

3) Is there a way to have the document rendered in Landscape (currently it is in portrait)?

4) Are there HTML tags / attributes which will help control where page breaks occur in the rendered PDF?

5) Is there a mechanism to load HTML directly into a PDF without using a URL?

6) Is there any way to pass HTTP authentication information (headers / cookies) when loading HTML from a URL?

Thanks in advance.

private void button2_Click(object sender, EventArgs e) {
PdfDocument pdf = new PdfDocument();
string url = "http://www.google.com";
pdf.LoadFromHTML(url, true, true, true);
pdf.SaveToFile(@"C:\SpireTest.pdf");
pdf.Close();
DocViewer(@"C:\SpireTest.pdf");
}

private void DocViewer(string fileName) {
try {
System.Diagnostics.Process.Start(fileName);
} catch { }
}

Hello Michael,

Thanks for your inquiry.

1) We are currently using the PdfDocument LoadFromHTML method. When I use the following code, the PDF generated from www.google.com contains scroll bars. Does the process of converting to HTML depend on loading a web browser / rendering engine?

Yes, it does.

2) Do you have documentation or suggestions for formatting the HTML / CSS to avoid scroll bars? Is there a suggested width?

If the HTML has set body's overflow style as scroll, it will appear the scroll bar after converting to the PDF. Please refer to the link http://www.w3schools.com/cssref/pr_pos_overflow.asp to avoid scroll bar.

3) Is there a way to have the document rendered in Landscape (currently it is in portrait)?

There is a way to have the document rendered in Landscape as below, please refer to it.
Code: Select all
PdfDocument pdf = new PdfDocument();
PdfSection pdfsec = pdf.Sections.Add();
pdfsec.PageSettings.Orientation = PdfPageOrientation.Landscape;
string url = "http://www.google.com";
pdfsec.LoadFromHTML(url, true, true,new PdfHtmlLayoutFormat
            {
                FitToPage=Clip.Both
            }
            );

Regarding the issue4, 5 and 6, now our product doesn't support these functions, and it has been transferred to our Dev team, they are discussing if they will develop these new features. Sorry for inconvenience.

If there are any questions, welcome to get it back to us.

Sincerely,
Gary

Gary,

Thanks for your reply. In regards to loading a web browser / rendering engine, can you tell me which one is used, so that we know how to best structure our HTML and CSS?

Thanks

Right now, we are looking for a solution that supports page-break-inside and page-break-before CSS attributes, or something equivalent. Thanks for your help.
