try
HPDF.AutoLaunch := true; // PDF file will be shown automatically
HPDF.FileName := '.\Curve.pdf'; // Set PDF filename
HPDF.BeginDoc; // Create PDF file
HPDF.CurrentPage.MoveTo( 50, 300 ); // Move first point
HPDF.CurrentPage.CurveToV(150, 50, 200, 200); // Draw curve
HPDF.CurrentPage.Stroke; // Stroke curve
HPDF.EndDoc; // Close PDF file
