A valid geospatial measure dictionary requires at least the keys /GCS and /GPTS. All other keys are

optional.

Example C++:

SI32 TestGeo(const PPDF* PDF, wchar_t* OutFileName)

{

pdfCreateNewPDFW(PDF, OutFileName);

pdfSetDocInfoA(PDF, diProducer, NULL);

SI32 bufSize;

// This example assumes that the above example string was copied to the file geo.txt.

char* attr = GetFileBuf("e:/geo.txt", bufSize);

// This code creates just an emptry page and adds a viewport to it. Open the file in

// Acrobat and check the coordinates with the Geospatial Location Tool, for example.

// It must show valid latitute and longitute coordinates. Distances can be measured

// too.

pdfAppend(PDF);

pdfSetBBox(PDF, pbMediaBox, 0.0, 0.0, 841.88806, 1190.54883);

SI32 vp = pdfCreateViewport(PDF, "Test", 51.2673, 88.08751, 793.90894, 1085.48682);

pdfCreateGeospatialMeasure(PDF, vp, attr);

free(attr);

pdfEndPage(PDF);

return pdfCloseFile(PDF);

}

Return values:

If the function succeeds the return value is the handle of the measure dictionary, a value greater or

equal zero. If the function fails the return value is a negative error code.
