GetVerticalTextHeight

Text

Description

Reports how far a run of text will travel down the page.

Syntax

Delphi

Function TPDFlib.GetVerticalTextHeight(Const FontName: WideString;
  Size: Double; Const Text: WideString): Double;

Parameters

FontName	An installed face, by name.
Size	Text size in points.
Text	The text to measure.

Return values

Distance	How far the run travels, in points.
0	The text or the face was empty, the size was not positive, or the face could not be read.

Remarks

Measures without drawing, so a column can be sized before it is committed to. A face carrying no vertical metrics of its own is measured at one em per character.

The measurement covers the forms that will actually be drawn, so a column whose brackets or vowel marks change shape vertically is measured as it will appear.
