Dear goga77,

There is no any limitations on the page count when convert html to PDF. And sorry that we cannot reproduce the issue you mentioned at our end.
Could you please provide us the HTML and the codes you were using so that we can look into it further ?

Dim htmlLayoutFormat As New PdfHtmlLayoutFormat() With { _
.IsWaiting = True, _
.LoadHtmlTimeout = 1000000, _
.Layout = PdfLayoutType.Paginate, _
.FitToHtml = Clip.Both _
}

Dim path As String = Dts.Variables("User::PDFName").Value.ToString


Dim setting As New PdfPageSettings()

setting.Size = PdfPageSize.A4

pdf.PageScaling = PdfPrintPageScaling.ActualSize


For Each row As DataRow In dt.Rows
For Each column As DataColumn In dt.Columns
stringhtml += row(column.ColumnName).ToString()
Next
stringhtml += vbCr & vbLf
Next

pdf.LoadFromHTML(stringhtml, True, setting, htmlLayoutFormat)

pdf.SaveToFile(path, FileFormat.PDF)
pdf.Close()
pdf.Dispose()

Dear goga77,

Thanks for the codes.
I have tesed the codes with Spire.PDF Pack(Hot Fix) Version:3.7.292 and found you use PdfLayoutType.Paginate and FitToHtml = Clip.Both together, and it will throw an expection. So I comment FitToHtml = Clip.Both. Finally, I can create a pdf which has 170 pages. Please make sure the html code you used is unbroken. And if the issue still exists, please provide us your sample HTML for investigation.
Here is my testing code for your kind reference:

Code: Select all

Dim dt As New DataTable()
dt.Columns.Add("test", GetType(String))
For i As Integer = 0 To 4999
   dt.Rows.Add("<p>testing</p>")
Next

Dim pdf As New PdfDocument()
   'FitToHtml = Clip.Both
Dim htmlLayoutFormat As New PdfHtmlLayoutFormat() With { _
.IsWaiting = True, _
 .LoadHtmlTimeout = 1000000, _
.Layout = PdfLayoutType.Paginate _
}

Dim stringhtml As String = Nothing
For Each row As DataRow In dt.Rows
   For Each column As DataColumn In dt.Columns
      stringhtml += row(column.ColumnName).ToString()
   Next
Next

Dim setting As New PdfPageSettings()
setting.Size = PdfPageSize.A4
pdf.PageScaling = PdfPrintPageScaling.ActualSize
pdf.LoadFromHTML(stringhtml, True, setting, htmlLayoutFormat)
pdf.SaveToFile("8642.pdf", FileFormat.PDF)

I coment "FitToHtml = Clip.Both", actualy that was just a try. Does not work. Spire always try to pack PDF to 30 page max. Sometimes when a html string is not so big it pass but with very small letter. When is very big it cut it on 30 page.

I want to convert html to pdf in SSIS package. I do not know where to copy new plugin.

[Betsy.jiang]

Dear goga77,

Thanks for your inquiry.
Here is the article(http://www.e-iceblue.com/Tutorials/Spir ... lugin.html). Please click HTMLConvertor-0.2.3.3.zip, it will download a package, and then unzip it, you can find the folder 'plugins'.
And then copy the folder 'plugins' under the same folder of Spire.Pdf.dll. Or add the following code to specify the plugins path directly, as below.

Code: Select all

Spire.Pdf.HtmlConverter.Qt.HtmlConverter.PluginPath = @"F:\demo\SSIS\plugins\";

If there is any question, welcome to get it back to us.

I am working on converting a Html file to PDF using Spire.PDF 2.6.0 and Spire.Doc 9.7.14. I am using .Net Core 3.1. The html file had style and page breaks. However the generated PDF file doesn't look like the html file, the text is overlapping and on the top of it the document shows html tags and this text is superimposed "Evaluation Warning: The document was created with Spire.Doc for .NET". We are using license version of Spire. We need technical support to resolve this issue. Please advise how to engage support team to fix it

Thanks
