Letter Spacing

Control the spacing between characters with positive values for wider spacing or negative for tighter.

doc := template.New(
    template.WithPageSize(document.A4),
    template.WithMargins(document.UniformEdges(document.Mm(20))),
)

page := doc.AddPage()
page.AutoRow(func(r *template.RowBuilder) {
    r.Col(12, func(c *template.ColBuilder) {
        c.Text("Letter Spacing Demo", template.FontSize(20), template.Bold())
        c.Spacer(document.Mm(8))

        c.Text("Normal spacing (0pt)")
        c.Spacer(document.Mm(3))

        c.Text("Letter spacing 1pt", template.LetterSpacing(1))
        c.Spacer(document.Mm(3))

        c.Text("Letter spacing 3pt", template.LetterSpacing(3))
        c.Spacer(document.Mm(3))

        c.Text("WIDE HEADER", template.FontSize(16), template.Bold(),
            template.LetterSpacing(5))
        c.Spacer(document.Mm(3))

        c.Text("Tight spacing -0.5pt", template.LetterSpacing(-0.5))
    })

page.AutoRow(func(r *template.RowBuilder) {
