Rich text is represented by PdfFormattedText class that allows you to:
- Append text and line breaks.
- Set various formatting options, such as alignment, font (family, style, weight, stretch, and size), language, color, and opacity.
- Set the maximum width of text or the maximum width of each line of text, and line height.
- Set the text formatting mode (implementation of the text layout and text shaping).
- Get the formatted text width and height.
Fonts used in the above example are system fonts and should be located in the directory designated by your operating system. To use non-system fonts (either from a custom directory or embedded in an assembly), see the Fonts example.
The text from the above example is formatted to an infinite width. The next example shows how to format text to a finite width, with various alignments, and demonstrates how to use text size information to draw text at various positions. The following example shows how to align and position text at various positions in the PDF page. The above example shows how to position text on a single page. To position text on multiple pages, see the Header and Footer example. The following example shows how to apply various transformations, such as rotation or scaling, to text drawn on a PDF page. The above example shows how to transform text on a single page. To transform text on multiple pages, see the Watermarks example. The following example shows how to write text from complex scripts, such as Arabic, Hebrew, various Indic, and others. Note that formatting Left-to-Right complex scripts, such as various Indic scripts, and Right-to-Left complex scripts, such as Arabic, works via WPF (by setting the The following example shows how to format each text line into a different width and how to draw a text line on a next page if it doesn't fit on the current one.Text alignment and positioning
