# NNS_G2dFontGetTextHeight

## Syntax

      #include <nnsys/g2d/g2d_Font.h>

      int NNS_G2dFontGetTextHeight(
      	const NNSG2dFont* pFont,
      	int vSpace,
      	const NNSG2dChar* txt
      );

## Arguments

pFont | [IN] Pointer to font
vSpace | [IN] Line interval (in pixels)
txt | [IN] Pointer to text string

## Return Values

Returns the height of the text string when drawn (in pixels).

## Description

Calculates the height of text string txt when drawn.

For information on the other arguments, see `NNS_G2dTextCanvasInit`.

Use this function when you want to know the size of the string before creating the `TextCanvas`. For example, use it when you are dynamically creating the smallest `CharCanvas` that can display all of txt. When `TextCanvas` is already created, use `NNS_G2dTextCanvasGetTextHeight`.

For a vertically written font, this function calculates the width of the text string.
