pdfSetFillColorF

BOOL32 __stdcall pdfSetFillColorF(PPDF IPDF, float* Color, uint32_t NumComponents);
BOOL32 __stdcall pdfSetStrokeColorF(PPDF IPDF, float* Color, uint32_t NumComponents);

function pdfSetFillColorF(const IPDF: PPDF; Color: PSingle; NumComponents: Cardinal): LongBool; stdcall;
function pdfSetStrokeColorF(const IPDF: PPDF; Color: PSingle; NumComponents: Cardinal): LongBool; stdcall;

Purpose. Set the fill (resp. stroke) color from a float array, each component already normalized to 0.0..1.0.

Description. Identical to pdfSetFillColorEx/pdfSetStrokeColorEx in every respect except that the NumComponents values read from Color are Single floats already in 0.0..1.0 and are passed through to EmitColorComps without the /255.0 normalization the Ex variant applies. Passing a byte-range value (e.g. 255.0) here will saturate/clip rather than normalize — the two entry points are not interchangeable despite accepting the same component count.

Parameters.

Return value. True on success; False if there is no current content stream.
