The Graphics Library (graphics.library) is a core component of AmigaOS Kickstart ROM, providing the primary API for all bitmap rendering and display operations. It abstracts hardware access to the custom chips (Denise/Alice), offering functions for drawing lines, rectangles, text, and sprites while managing display buffers and collision detection. Applications rely on this library to ensure compatibility across different Amiga models, from OCS to AGA systems, without direct hardware manipulation.
