First of all, please make sure the encoding of your console is UTF8. Utf8 encoding is the default encoding of the html document:
Console.InputEncoding = Encoding.UTF8PdfConvert.Environment.Debug = False
PdfConvert.ConvertHtmlToPdf(New PdfDocument With {
.Url = "input.html"
}, New PdfOutput With {
.OutputFilePath = "output.pdf"
})
PdfConvert.ConvertHtmlToPdf(New PdfDocument With {
.Url = "input.html",
.HeaderLeft = "[title]",
.HeaderRight = "[date] [time]",
.FooterCenter = "Page [page] of [topage]"
}, New PdfOutput With {
.OutputFilePath = "output.pdf"
})PdfConvert.ConvertHtmlToPdf(New PdfDocument With {
.Html = "<html><h1>test</h1></html>"
}, New PdfOutput With {
.OutputFilePath = "inline.pdf"
})
PdfConvert.ConvertHtmlToPdf(New PdfDocument With {
.Html = "<html><h1>測試</h1></html>"
}, New PdfOutput With {
.OutputFilePath = "inline_cht.pdf"
})Actually, you can construct a html document content from XElement directly in your VB code:
' In this case, we use HTMLDocument object instead of PdfDocument object
Dim html As New HTMLDocument With {
.HTML =
<html>
<head>
<title>Hello World!</title>
</head>
<body>
<h1>Hello World!!!</h1>
<hr/>
<h2>Example code</h2>
<code>
<pre>
Public Function Main() As Integer
Call println("Hello world!")
Return 0
End Function
</pre>
</code>
<h4>Another header</h4>
<table>
<thead>
<tr>
<th>1</th>
<th>2</th>
<th>3</th>
</tr>
</thead>
<tr>
<td>a</td>
<td>b</td>
<td>c</td>
</tr>
</table>
<footer style="position:fixed; font-size:.8em; text-align:right; bottom:0px; margin-left:-25px; height:20px; width:100%;">
Here is the PDF document footer.
</footer>
</body>
</html>
}
Call println(html.GetDocument)
Call PdfConvert.ConvertHtmlToPdf(html, App.HOME & "/hello-world.pdf")# markdown2pdf
markdown2pdf ./input.md
# Due to the reason of markdown parser is compatible with html format,
# so that convert from a html file is also works fine!
markdown2pdf ./input.htmlThere are some special placeholer can be used for the html template rendering:
[#page]for create page number dynamics[#h1]for create the master header numbers[#h2]for create the secondary header numbers[#h3]for create the header numbers in third level[#h4]for create the header numbers in fourth level[#fig]for create the figure numbers[#tab]for create the table numbers
