pdfSetExtColorSpace

Purpose — Nominally: set the "current" extended color space handle.

Description — Stores Handle into FExtColorSpaceH and always returns TRUE, with no validation. That field is never read elsewhere in the codebase — this call has no effect on any drawing operation or serialized output.

Declarations

BOOL32 __stdcall pdfSetExtColorSpace(PPDF IPDF, uint32_t Handle);

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

Parameters

Return value — Always TRUE on a valid handle; FALSE on an invalid IPDF. The success return gives no indication of the no-op behavior.

Remarks — For color spaces that actually affect output, use pdfSetFillColorSpace/pdfSetStrokeColorSpace (not in this chapter) or the concrete color-setting calls (pdfSetFillColor, pdfSetSeparationColor, etc.) that write real content-stream color operators.
