`pdfSetTextRect`

Set the rectangle [pdfWriteFText](E01_CoreTextOutput.md#api-pdfwriteftext)

Category	Text state / flowed text

Purpose — Set the rectangle pdfWriteFText (the non-Ex form) and pdfGetFTextHeight (the non-Ex form) draw/measure into.

Description — This call cannot itself fail — it always returns TRUE (there is no document/page precondition, since it only stores four doubles). A rectangle is considered "active" (FHasTextRect) only when both Width and Height are > 0; passing 0 or a negative size for either deactivates flow text until reset.

Declarations

BOOL32 __stdcall pdfSetTextRect(PPDF IPDF, double PosX, double PosY, double Width, double Height);

Delphi

function pdfSetTextRect(const IPDF: PPDF; PosX, PosY, Width, Height: Double): LongBool; stdcall; external 'LumasPdf.dll';

Parameters

Parameter	Type	Description
`IPDF`	`PPDF`	Instance handle.
`PosX`, `PosY`	`Double`	Top-left of the rectangle.
`Width`, `Height`	`Double`	Size; both must be `> 0` to activate the rectangle.

Return value — Always TRUE on a valid handle.
