Canvas 2 is the updated version of my older iOS library, Canvas! While the first version uses mostly built in constructs from Core Graphics, this new version takes full advantage of the Metal 2 API. This means that Canvas can now support a wider range of features and do so more efficiently by taking advantage of the GPU.

• Canvas: A view that allows for drawing on the screen.
• Tools: Play around with different tools such as the pencil, eraser, line, rectangle, and ellipse.
• Layers: Create multiple layers on the canvas that can be removed, locked, swapped, etc.
• Brushes: Register different brushes on the canvas and swap between them at any time.
• Textures: Each brush supports a texture property so that you can customize your paint strokes based on your choice of image.
• Events: Keep track of when certain actions occur on the canvas by implementing the CanvasEvents protocol.
• Undo/Redo/Clear: Add custom undo and redo actions, and clear the canvas as well as specific layers.
• Export: Export your canvas/layers to a UIImage or to Data.
• Codable: Canvas implements the Codable protocol, which makes saving and loading your canvas data easy.

• Selection: Move entire layers, or selected pixels around the screen.
