`pdfSetExtGState`

Apply a previously-created /ExtGState resource to the

Category	Extended graphics state

Purpose — Apply a previously-created /ExtGState resource to the current content stream.

Description — Emits a /GSn gs operator referencing the resource created by pdfCreateExtGState(Handle). This is the step that actually puts the graphics state (alpha, blend mode, etc.) into effect from this point in the content stream forward — creating the resource alone (pdfCreateExtGState) does not apply it.

Declarations

BOOL32 __stdcall pdfSetExtGState(PPDF IPDF, uint32_t Handle);

Delphi

function pdfSetExtGState(const IPDF: PPDF; Handle: Cardinal): LongBool; stdcall; external 'LumasPdf.dll';

Parameters

Parameter	Type	Description
`IPDF`	`PPDF`	Instance handle with an open page/content stream.
`Handle`	`Cardinal`	Handle from `pdfCreateExtGState`.

Return value — TRUE on success; FALSE if Handle doesn't resolve to a registered ExtGState, or no content stream is open.
