`psrSetLineCapStyle`

Read/write the line-cap sub-field (bits 8-9) of a

TLineCapStyle __stdcall psrGetLineCapStyle(uint32_t DrawParms);
void __stdcall psrSetLineCapStyle(uint32_t* DrawParms, TLineCapStyle Value);

Delphi

function psrGetLineCapStyle(DrawParms: Cardinal): TLineCapStyle; stdcall;
procedure psrSetLineCapStyle(var DrawParms: Cardinal; Value: TLineCapStyle); stdcall;

Purpose. Read/write the line-cap sub-field (bits 8-9) of a caller-owned packed DrawParms word.

Description. Same masked read-modify-write pattern as psrGetBlendMode/psrSetBlendMode, over bits 8-9 ((DrawParms shr 8) and 3 / clear-then-OR Value shl 8). TLineCapStyle is (csButtCap, csRoundCap, csSquareCap) — 3 values, ordinals 0..2, fitting the 2-bit field exactly.

Parameters.

Parameter	Description
`DrawParms`	(Get) The packed word to read. (Set) `var` — modified in place; only bits `8-9` change.
`Value`	(Set only) New `TLineCapStyle` ordinal (`0..2`).

Return value. psrGetLineCapStyle: the decoded TLineCapStyle. psrSetLineCapStyle: none.

See also. pdfGetLineCapStyle (the unrelated, document-level equivalent — do not confuse the two mechanisms).
