Core Graphics is a powerful 2D drawing engine used in Apple's operating systems, including iOS and macOS. It provides developers with tools to create graphics, images, and text, allowing for precise control over rendering. Core Graphics is built on the Quartz framework, which enables high-quality graphics and supports various file formats. The framework is widely used for tasks such as creating custom user interfaces, rendering images, and generating PDF documents. By leveraging Core Graphics, developers can enhance the visual appeal of their applications while ensuring smooth performance and scalability across different devices and screen sizes.
