Draw an Arc in C#

This example shows how to create a bitmap, draw an arc, and save the image in C# using Aspose.Drawing for .NET.

// Create a bitmap object
using (var bitmap = new Bitmap(1000, 800))
{
    // Initialize a Graphics object with the bitmap
    using (var graphics = Graphics.FromImage(bitmap))
    {
        // Define a pen with color and width
        using (var pen = new Pen(Color.Blue, 2))
        {
            // Draw an arc on the bitmap
            graphics.DrawArc(pen, new Rectangle(0, 0, 700, 700), 0, 180);

            // Save the image as PNG
            bitmap.Save("output_arc.png");
        }
    }
}

Draw Text with Anti-Aliasing in C#

Demonstrates how to render anti-aliased text inside a clipped ellipse area using Aspose.Drawing for .NET.

// Create a bitmap object
using (var bitmap = new Bitmap(1000, 800))
{
    // Initialize a Graphics object with anti-aliasing
    using (var graphics = Graphics.FromImage(bitmap))
    {
        graphics.TextRenderingHint = TextRenderingHint.AntiAliasGridFit;

        // Create a GraphicsPath representing an ellipse
        var path = new GraphicsPath();
        path.AddEllipse(new Rectangle(200, 200, 400, 200));

        // Clip the text inside the ellipse
        graphics.SetClip(path);

        // Define font, brush, and format for the text
        var font = new Font("Arial", 20);
        var brush = new SolidBrush(Color.Black);
        var format = new StringFormat { Alignment = StringAlignment.Center };

        // Draw the string within the clipped ellipse
        graphics.DrawString("Hello World!", font, brush, new RectangleF(200, 200, 400, 200), format);

        // Save the image
        bitmap.Save("output_text.png");
    }
}

Create a Bezier Spline in C#

This snippet demonstrates drawing a Bezier spline using the DrawBezier method in Aspose.Drawing for .NET.

// Create a bitmap object
using (var bitmap = new Bitmap(1000, 800))
{
    // Initialize a Graphics object
    using (var graphics = Graphics.FromImage(bitmap))
    {
        // Define a pen for drawing
        using (var pen = new Pen(Color.Blue, 2))
        {
            // Define control points for Bezier curve
            Point pt1 = new Point(100, 100);
            Point pt2 = new Point(200, 10);
            Point pt3 = new Point(350, 400);
            Point pt4 = new Point(500, 300);

            // Draw the Bezier curve
            graphics.DrawBezier(pen, pt1, pt2, pt3, pt4);

            // Save the image
            bitmap.Save("output_bezier.png");
        }
    }
}
