How to get positioned TextFragment to overflow to new page?

Aspose.PDF Product Family

#1

I am trying to write some variable length text to a PDF page that I need to be able to position and have overflow to a new page if the text extends passed the bottom of the current page.

I tried using TextParagraph and TextFragment with TextBuilder but I have not been able to successfully get the text to overflow to a new page. If I set the Position property of TextParagraph or TextFragment, it will write all of the text on the same page with no overflow. If I position the text by setting the Rectangle property, it truncates the text wherever the rectangle ends.

Is there a built in way or a workaround that I can use to position the text and have it overflow to a new page if necessary?

Please use TextFragment as shown below to get the desired output. Hope this helps you.

Document pdfDocument = new Document(inputFilePath);
Aspose.Pdf.Text.TextFragment text = new Aspose.Pdf.Text.TextFragment("A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog.");
text.Position = new Position(20, 10);
text.TextState.FormattingOptions = new Aspose.Pdf.Text.TextFormattingOptions()
{
SubsequentLinesIndent = 20
};
Aspose.Pdf.Page page = pdfDocument.Pages[1];
page.Paragraphs.Add(text);

string outputPath = usePosition ? positionParagraphOutput : rectangleParagraphOutput;
pdfDocument.Save(outputPath);

I ran a test using code similar to your solution above. I was able to get the text to position correctly and overflow to a new page.

However, I’m getting a strange behavior where several blank pages are being inserted into the document between the first page and where the text I am adding programmatically is being placed. I’m not sure if this is something I am doing incorrectly or if it is a bug.

Here are some updated examples and source code for you to reference. PageOverflowSample_12_7.zip (236.8 KB)
