`pdfOptimize`

Run document-size optimization (e.g. removing unused objects,

BOOL32 __stdcall pdfOptimize(PPDF IPDF, TOptimizeFlags Flags, POptimizeParams Parms);

Delphi

function pdfOptimize(const IPDF: PPDF; Flags: TOptimizeFlags; Parms: POptimizeParams): LongBool; stdcall;

Purpose. Run document-size optimization (e.g. removing unused objects, deduplicating resources) per Flags.

Description. Flags is real and reaches OptimizeDoc. Parms — a struct presumably carrying fine-grained optimization thresholds/options — is accepted by the ABI but never passed through; whatever detailed tuning the struct's fields imply has no effect regardless of its contents.

Parameters.

Parameter	Description
`IPDF`	Document handle.
`Flags`	Optimization flag set; genuinely consulted.
`Parms`	Accepted but silently dropped — has no effect.

Return value. True if IPDF is valid; False otherwise.
