GetFTextHeight

Syntax:

double pdfGetFTextHeight(

const PPDF* IPDF,

// Instance pointer

TTextAlign Align,

// Base text alignment

const char* AText) // Formatted text

typedef enum

{

taLeft,

taCenter,

taRight,

taJustify

}TTextAlign;

The function measures the height of a formatted text block. Before calling this function a font (see

SetFont()) and the output rectangle must be set with the function SetTextRect(). The parameter

Height of SetTextRect() should be set to -1 to avoid page breaks. Otherwise the height of the first text

block is returned that fits into the given height of the rectangle.

The parameter AText must contain the same text (incl. format tags if any) as which should be

printed later with WriteFText().

Remarks:

This function is implemented in an Ansi and Unicode compatible version.

Return values:

If the function succeeds the return value is the height of the formatted text block. If the function fails

the return value is a negative error code.

GetFTextHeightEx

Syntax:

double pdfGetFTextHeightEx(

const PPDF* IPDF,

// Instance pointer

double Width,

// Width of output rectangle

TTextAlign Align,

// Base text alignment

const char* AText) // Formatted text

The function measures the height of a formatted text block. The function works in the same way as

GetFTextHeight() but the output rectangle must not be set manually beforehand.

The height of the output rectangle is set to -1 to avoid a page break during measuring.
