Hi Matanya,

Thank you for your patience,

PdfStringFormat.ClipPath: If we enable the Clip Path option, the text rendering mode is set to a clipping mode within a text object.

PdfStringFormat.LineLimit: The default value of the LineLimit property is true. If we set the LineLimit, the provided string will be laid out within the specified bounds. If we disable the LineLimit property, the layout will continue with the remaining spaces.

PdfStringFormat.NoClip: If we enable the NoClip option, it will show the text without cutting any words. If we disable the NoClip option, any text outside the fitting area will be hidden.

LineLimit	NoClip	Result
true	true
false	true
true	false
false	false

Please find the code example below,

string text = @"PdfStringFormat 1

PdfStringFormat 2

PdfStringFormat 3

PdfStringFormat 4

PdfStringFormat 5

";

 

PdfStringFormat format = new PdfStringFormat();

format.ClipPath = true;

format.NoClip = false;

format.LineLimit = false;

 

PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 12);

 

PdfDocument document = new PdfDocument();

document.PageSettings.Margins.All = 0;

PdfPage page = document.Pages.Add();

PdfGraphics graphics = page.Graphics;

 

MemoryStream stream = new MemoryStream();

graphics.DrawRectangle(PdfPens.Red, new RectangleF(100, 100, 100, 20));

graphics.DrawString(text, font, PdfBrushes.Black, new RectangleF(100, 100, 100, 20), format);

 

document.Save(“Output.pdf”);
