pdfSetLineWidth

double __stdcall pdfGetLineWidth(PPDF IPDF);
BOOL32 __stdcall pdfSetLineWidth(PPDF IPDF, double Value);

function pdfGetLineWidth(const IPDF: PPDF): Double; stdcall;
function pdfSetLineWidth(const IPDF: PPDF; Value: Double): LongBool; stdcall;

Purpose. Set/get the current stroke line width, in user-space units (points, absent a scaling CTM).

Description. Caches into FCurLineWidth and emits a w line-width operator via WriteLineWidth immediately — real, same pattern as cap/join. No range clamping is applied (unlike pdfSetOpacity below); a negative or zero width is passed through to the content stream unmodified, at the PDF viewer's discretion to interpret (0 conventionally renders a device-thinnest line).

Parameters.

Return value. pdfSetLineWidth: True on success, False if no current content stream. pdfGetLineWidth: the cached current width; 0.0 if IPDF is invalid.
