`psrGetLineJoinStyle`

Read/write the line-join sub-field (bits 12-13) of a

TLineJoinStyle __stdcall psrGetLineJoinStyle(uint32_t DrawParms);
void __stdcall psrSetLineJoinStyle(uint32_t* DrawParms, TLineJoinStyle Value);

Delphi

function psrGetLineJoinStyle(DrawParms: Cardinal): TLineJoinStyle; stdcall;
procedure psrSetLineJoinStyle(var DrawParms: Cardinal; Value: TLineJoinStyle); stdcall;

Purpose. Read/write the line-join sub-field (bits 12-13) of a caller-owned packed DrawParms word.

Description. Same masked read-modify-write pattern, over bits 12-13 ((DrawParms shr 12) and 3 / clear-then-OR Value shl 12). TLineJoinStyle is (jsMiterJoin, jsRoundJoin, jsBevelJoin) — 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 `12-13` change.
`Value`	(Set only) New `TLineJoinStyle` ordinal (`0..2`).

Return value. psrGetLineJoinStyle: the decoded TLineJoinStyle. psrSetLineJoinStyle: none.

See also. pdfGetLineJoinStyle (the unrelated, document-level equivalent).
