Hello Support , How to implement the property Display Header in Html to Pdf with plugin?

[Herman.Yan]

Hi,

Thank you for your message.
Kindly note that the plugin method uses third-party HtmlConverter.QT of the Chrome kernel, there is no direct way to add header when doing the conversion. However, you can refer to this tutorial (Add Header to Existing PDF in C#/VB.NET) to add the header on the converted PDF file. If you have any questions after the test, please share your input Html and desired output PDF file for further investigation. you can upload them here or provide to us by email (support@e-iceblue.com)

hello, the desired effect for which I have not found a property is to adjust all the contents of the pdf almost completely on the left side, so you can see in the pdf that I send that the left side has a very large space between the information and the beginning from the sheet on the left side, could there be a setting in this code that I use to reduce that and make it look more proportional?
I share the code...

var memoryStream = new MemoryStream();
HtmlConverter.Convert(htmlDocument, memoryStream,
true, 100000, new SizeF(993,1133),
new Spire.Pdf.Graphics.PdfMargins(0,0),
LoadHtmlType.SourceCode);

[jorgelux]

the desired effect is all at the root of the sheet so that not so much space is seen

Hi,

Thank you for your message.
When converting Html to PDF，there is no direct way to reduce the blank space part. However, you can refer to the following code to process the converted PDF file. The attachment is my testing result. If you have other questions, just feel free to write back.

Code: Select all

 PdfDocument doc = new PdfDocument();
 // Read a pdf file
 doc.LoadFromFile(@"ADM10-PANOVO ALIMENTARIA S DE RL de CV,Panovo -20_mar._23 (5).pdf");
 // Creates a new page
 PdfDocument newDoc = new PdfDocument();
 // Get page margins of source pdf page
 PdfMargins margins = doc.PageSettings.Margins;
 float top = margins.Left;
 float bottom = margins.Bottom;
 float left = margins.Left;
 float right = margins.Right;

 foreach (PdfPageBase page in doc.Pages)
 {
     // Adds a new page to the new document
     PdfPageBase newPage = newDoc.Pages.Add(new SizeF(page.Size.Width - left-50 - right, page.Size.Height - top - bottom), new PdfMargins(0));
     // Draws the content of the source page onto the new document page
     newPage.Canvas.DrawTemplate(page.CreateTemplate(), new PointF(-left-50, -top));
 }
 String result = @"out.pdf";
 //Save the document
 newDoc.SaveToFile(result);
