Using Font Kerning and Tracking in PDF (.NET Core/Framework)
Using Font Kerning and Tracking in a PDF using DynamicPDF Core Suite is straightforward. Kerning (different from tracking) is a font's ability to adjust the spacing between certain pairs of letters. Tracking, is the amount of overall space between all letters.
How to Use Font Kerning and Tracking in a PDF
The following steps and sample code illustrate using Font Kerning and Tracking in a PDF document using DynamicPDF Core Suite.
Steps for Using Fonts in a PDF Document
- Create a
Document
object. - Create a
Page
object. - Create a
TextArea
object and add the text to be displayed. - Enable Kerning for the Textarea by setting the
KerningEnabled
property to true . - Loop over the entire TextArea's KernValues' Spacing array and assign a certain value for every pair (or a subset of pairs). Assign positive value for making the space between chars closer and negative value for making the space further.
- Save the PDF document.
Sample Code - C#
Document document = new Document();
Page page = new Page();
string text = "To and WA are examples of when kerning would be used.";
TextArea textArea = new TextArea(text, 10, 10, 400, 700, Font.TimesRoman);
textArea.KerningEnabled = true;
KerningValues kernValues = textArea.GetKerningValues();
for (int i = 0; i < kernValues.Spacing.Length; i++)
{
kernValues.Spacing[i] = (short)(kernValues.Spacing[i] - 400);
}
page.Elements.Add(textArea);
document.Pages.Add(page);
document.Draw(@"Output.pdf");
