Text rise

Docotic.Pdf Library Help > Samples > Text > Text rise

This sample shows how to adjust baseline of text (useful for drawing superscripts or subscripts) using PdfCanvas.TextRise property.

Text rise specifies the distance to move the baseline up or down from its default location. A positive value for PdfCanvas.TextRise property moves the baseline up, a negative value moves the baseline down.
