`pdfGetFTextHeightEx`

Same as [pdfGetFTextHeight](#api-pdfgetftextheight), but

Category	Text measurement
Note	same format-tag caveat as `pdfGetFTextHeight`

Purpose — Same as pdfGetFTextHeight, but takes Width explicitly instead of reading the current text rectangle.

Declarations

double __stdcall pdfGetFTextHeightExA(PPDF IPDF, double Width, int32_t Align, const char* AText);
double __stdcall pdfGetFTextHeightExW(PPDF IPDF, double Width, int32_t Align, const wchar_t* AText);

Delphi

function pdfGetFTextHeightExA(const IPDF: PPDF; Width: Double; Align: Integer; const AText: PAnsiChar): Double; stdcall; external 'LumasPdf.dll';
function pdfGetFTextHeightExW(const IPDF: PPDF; Width: Double; Align: Integer; const AText: PWideChar): Double; stdcall; external 'LumasPdf.dll';

Parameters

Parameter	Type	Description
`IPDF`	`PPDF`	Instance handle.
`Width`	`Double`	Rectangle width to simulate wrapping against.
`Align`	`Integer`	Accepted but not read — see `pdfGetFTextHeight`.
`AText`	string	Text to measure. Same tag-parsing caveat as `pdfGetFTextHeight`.

Return value — Predicted height in points; 0.0 if Width <= 0, no font is selected, or AText is empty.
