I'm using WPF, and I have a RichTextBox in my user interface, which I convert to a PDF file. I take the RichTextBox.Document FlowDocument from the RichTextBox and translate it to a PdfSharp.Pdf.PdfPage.
This has been working pretty good (after finding some help for wordwrap on SO), but I found that I need to scale the PDF, so after I get the font from the FlowDoc, I multiply it by a scale factor, in my case 0.88.
This appeared to work great, but on closer inspection, I found that a few lines were terminating early.
// these lines use font info from the FlowDoc. To simplify, I've
// hard-coded the font size.
// this works fine:
var thisRunXFont = new XFont(thisRun.FontFamily.Source, 14, xRunFontStyle);
// this causes problems:
var thisRunXFont = new XFont(thisRun.FontFamily.Source, 12.32, xRunFontStyle);
Has anyone else seen this kind of trouble? I do go on to use MeasureString() to get the enclosing paragraph -- but forcing the rectangle to be wider does not change the behavior.
