`rasInitColorManagement`

Enable viewer-side color management on the page cache.

BOOL32 __stdcall rasInitColorManagement(IPGC CachePtr, PPDFColorProfiles Profiles, TPDFInitCMFlags Flags);

Delphi

function rasInitColorManagement(CachePtr: IPGC; Profiles: PPDFColorProfiles; Flags: TPDFInitCMFlags): LongBool; stdcall;

Purpose. Enable viewer-side color management on the page cache.

Description. Partially real: the on/off state and flags are genuinely retained as real, queryable cache state, but the actual ICC profile data pointed to by Profiles is not stored at all — per the inline comment ("GAP-7: ... Retains the flags (and marks the cache colour-managed) so 'InitColorManagement active' is a real, queryable state that the tile renderer can honour. The profile blob is caller-owned; we keep the flags only."). Whether the tile renderer's color-managed path does anything beyond checking the boolean (e.g. actually applying an ICC transform) was not traced further in this chapter.

Parameters.

Parameter	Description
`CachePtr`	Target page cache.
`Profiles`	Accepted but not retained — only the fact that some profiles were supplied enables the flag; the actual profile bytes are not stored.
`Flags`	Genuinely stored (`CMFlags`).

Return value. True if CachePtr resolves; False otherwise (via the shared NotImplLogB path on failure).
