`pdfGetGlyphOutline`

Extract the point-contour outline of one glyph from the

Category	Glyph introspection
Note	current font only, and Type 1 fonts only (see Remarks)

Purpose — Extract the point-contour outline of one glyph from the currently active font.

Declarations

int32_t __stdcall pdfGetGlyphOutline(PPDF IPDF, uint32_t Index, PPDFGlyphOutline Outline);

Delphi

function pdfGetGlyphOutline(const IPDF: PPDF; Index: Cardinal; Outline: PPDFGlyphOutline): Integer; stdcall; external 'LumasPdf.dll';

Parameters

Parameter	Type	Description
`IPDF`	`PPDF`	Instance handle.
`Index`	`Cardinal`	Character code to extract the outline for.
`Outline`	`PPDFGlyphOutline`	Receives `PointCount`, `Points` (contour point array), `Advance`.

Return value — Point count (> 0) on success; 0 if the current font isn't a Type 1 font (this build's contour extractor is Type-1-specific — it does not work for TrueType, standard-14, or CID fonts, despite pdfGetGlyphIndex being the TrueType-specific sibling — the two calls cover mutually exclusive font kinds), or the glyph has no contours.

Memory & buffers — Outline.Points points at an engine-owned buffer valid until the next call to this function.

Remarks — real, verified asymmetry. pdfGetGlyphIndex works only for TrueType; pdfGetGlyphOutline works only for Type 1. There is no single call in this build that extracts outlines for a TrueType glyph.
