HTML Text Block

Just confirming that what I’m trying to do isn’t supported: I have a block of HTML text in a string that I’d like to inject into a PDF document. This seems to only be possible using Aspose.HTML. (We are evaluation switching from a competitor but one of the things we get from them in an HTMLStamp which acts like ImageStamp/TextStamp but will resolve HTML).


Aspose.PDF supports adding an HTML String in PDF document which will be rendered in the final document. Please check the below documentation topic for further information:

Please feel free to let us know in case you need more information.

I have this working but its not positioning the block where I expect.
var doc = new Aspose.Pdf.Document();
var html = new HtmlFragment("<span style=“color:red”>Some Italics
Some Bold");
var page = doc.Pages.Add();
html.TextState = new TextState();
html.TextState.ForegroundColor = Aspose.Pdf.Color.Green;
html.TextState.BackgroundColor = Aspose.Pdf.Color.Silver;
html.VerticalAlignment = VerticalAlignment.Bottom;
html.HorizontalAlignment = HorizontalAlignment.Left;
html.Margin.Bottom = 100;
html.Margin.Top = 100;
html.Margin.Left = 100;
html.Margin.Right = 100;
I would expect this to position the text near the bottom of the page but instead its about a 1/3 of the way down the page. The horizontal position was as expected. And the background/foreground colors don’t work but the style color did. Can you point me to details on how the Margin should operate.


Please try below code and see if it helps in achieving the required output:

var pdfDocument = new Document();
for (int i = 1; i <= pdfDocument.Pages.Count; i++)
 var hf = new Aspose.Pdf.HeaderFooter { Margin = new Aspose.Pdf.MarginInfo(40, 0, 40, 0) };
 String htmltable = "<span style=\"color:red\"><i>Some Italics</i><br/><b>Some Bold</b></span>";
 var html = new HtmlFragment(htmltable)
  Margin = new Aspose.Pdf.MarginInfo(0, 0, 0, 40)
 pdfDocument.Pages[i].Footer = hf;
 html.VerticalAlignment = VerticalAlignment.Top;
pdfDocument.Save(dataDir + "output.pdf");

This doesn’t look like a generalized solution to positioning objects. Is it not possible to specify the absolute position of a paragraph, graph, or other object on the page?


In that case, you can please use floating box to specify the position over page and add HtmlFragment inside it like below:

Document doc = new Document();
Page page = doc.Pages.Add();
FloatingBox floatingBox = new FloatingBox();
floatingBox.Left = 100;
floatingBox.Top = 100;
var htmlFragment = new HtmlFragment(html);
doc.Save(dataDir + "HTMLFragmentinFloatingBox.pdf");

That worked. I had stumbled on this feature was just trying to use it when this email arrived and confirmed that path.
Thank you.
