Using Font Kerning and Tracking in PDF (.NET Core/Framework)

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

1. Create a Document object.
2. Create a Page object.
3. Create a TextArea object and add the text to be displayed.
4. Enable Kerning for the Textarea by setting the KerningEnabled property to true .
5. 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.
6. 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");
