namespace HelloWorld

class Program
{
static void Main(string[] args)
{
// Create main PDF Doc Engine
PDFDocEngine engine = new PDFDocEngine("", "");

// Add new document
Document document = engine.AddDocument();

// Append new page to the document
Page page = document.AddPage(PageSizeType.A3, PageOrientationType.LandScape);

// Create new drawing
Drawing drawing = page.AddDrawing();

// Line width
const double lineWidth = 5.0f;

// Set Line Width
drawing.SetLineWidth(lineWidth);

// Move to start position
drawing.MoveTo(100, 100);

// X coordinate of 1st point
double point1X = 200.0f;
// Y coordinate of 1st point
double point1Y = 200.0f;
// X coordinate of 2nd point
double point2X = 300.0f;
// Y coordinate of 2nd point
double point2Y = 50.0f;
// X coordinate of 3rd point
double point3X = 400.0f;
// Y coordinate of 3rd point
double point3Y = 100.0f;

// Draw curve interpolated between 3 points
drawing.CurveTo(point1X, point1Y, point2X, point2Y, point3X, point3Y);

//Stroke curve
drawing.Stroke();

// Closing drawing on the page
drawing.Close();

// Save document
document.Save("Curves.pdf");

// open generated PDF document in default PDF viewer installed in Windows
Process.Start("Curves.pdf");
