Features
High Performance
Anti-aliased graphics
Efficient batch rendering
Minimal overhead with less than 1K lines of executable code
// Save current state
canvas.SaveState();
// Apply transformations
canvas.TransformBy(Transform2D.CreateTranslation(200, 200));
canvas.TransformBy(Transform2D.CreateRotate(45.0 * Math.PI / 180.0));
canvas.TransformBy(Transform2D.CreateScale(0.8, 0.8));
// Draw a rectangle at the transformed position
canvas.RectFilled(-40, -40, 80, 80, Color.FromArgb(200, 255, 150, 100));
// Restore previous state
canvas.RestoreState();
Line Styles
// Set line join style
canvas.SetStrokeJoint(JointStyle.Round);
canvas.SetStrokeWidth(8.0);
canvas.SetStrokeColor(Color.FromArgb(255, 100, 255, 100));
// Draw path with the specified style
canvas.BeginPath();
canvas.MoveTo(50, 50);
canvas.LineTo(150, 80);
canvas.LineTo(100, 150);
canvas.LineTo(200, 200);
canvas.Stroke();
// Different end caps
canvas.SetStrokeStartCap(EndCapStyle.Round);
canvas.SetStrokeEndCap(EndCapStyle.Square);
canvas.BeginPath();
canvas.MoveTo(250, 100);
canvas.LineTo(350, 200);
canvas.Stroke();
Scissor Clipping
// Save current state
canvas.SaveState();
// Set scissor region
canvas.Scissor(100, 100, 200, 150);
// Draw content that will be clipped by the scissor
canvas.CircleFilled(200, 180, 80, Color.FromArgb(180, 255, 100, 200));
// Reset scissor
canvas.ResetScissor();
// Restore previous state
canvas.RestoreState();
