`pdfGetFieldColor`

Get/set any field's background/border/text color by

BOOL32 __stdcall pdfGetFieldColor(PPDF IPDF, uint32_t AField, int32_t ColorType, int32_t* ColorSpace, uint32_t* Color);
BOOL32 __stdcall pdfSetFieldColor(PPDF IPDF, uint32_t AField, int32_t ColorType, int32_t CS, uint32_t Color);

Delphi

function pdfGetFieldColor(const IPDF: PPDF; AField: Cardinal; ColorType: Integer; var ColorSpace: Integer; var Color: Cardinal): LongBool; stdcall;
function pdfSetFieldColor(const IPDF: PPDF; AField: Cardinal; ColorType: Integer; CS: Integer; Color: Cardinal): LongBool; stdcall;

Purpose. Get/set any field's background/border/text color by explicit handle — the generalized counterpart of the cursor-based color functions above, usable against any field, not just the most recently created one.

Description. ColorType selects which of the three colors (0=background, 1=border, 2=text — matching the same numbering the cursor-based functions use internally). pdfSetFieldColor's CS parameter is accepted by the ABI but never passed through to SetFieldColorH — same dropped-color-space pattern already confirmed for pdfSetAnnotColor (Annotation Appearance and Properties); colors are always stored as RGB regardless of CS.

Parameters.

Parameter	Description
`IPDF`	Document handle.
`AField`	Target field handle — any field, not cursor-limited.
`ColorType`	`0`=background, `1`=border, `2`=text.
`CS`	(Set only) Accepted but silently dropped — always RGB.
`Color`	The color value.
`ColorSpace`	(Get only) Output color-space indicator.

Return value. True if AField resolves; False otherwise.
