`pdfCreateGeospatialMeasure`

Attach a geospatial (/Subtype /GEO) /Measure dictionary

int32_t __stdcall pdfCreateGeospatialMeasure(PPDF IPDF, uint32_t Viewport, const char* Attributes);

Delphi

function pdfCreateGeospatialMeasure(const IPDF: PPDF; Viewport: Cardinal; const Attributes: PAnsiChar): Integer; stdcall;

Purpose. Attach a geospatial (/Subtype /GEO) /Measure dictionary to an existing viewport — the geospatial counterpart of pdfCreateRectilinearMeasure (Patterns, Shadings, ExtGState Creation, and Template Placement), storing caller-supplied attributes (GCS WKT string) verbatim rather than computing a rectilinear scale ratio.

Parameters.

Parameter	Description
`IPDF`	Document handle.
`Viewport`	`1`-based index of an existing viewport on the current page.
`Attributes`	Caller-supplied geospatial coordinate-system attributes (typically WKT), stored verbatim.

Return value. The Viewport index on success; 0 if there is no open page or Viewport doesn't identify an existing viewport.
