Description: Screen coordinates are a reference system that specifies a position on a device’s screen, such as a monitor or mobile device display. These coordinates are generally expressed in a Cartesian coordinate system, where the origin (0,0) is located at the top-left corner of the screen. As you move to the right, the X coordinate value increases, while moving down increases the Y coordinate value as well. This system is fundamental in computer graphics, as it allows developers and designers to place visual elements, such as images, text, and shapes, at specific positions within the user interface. In graphics programming environments, screen coordinates are essential for rendering objects in the display window, facilitating real-time graphics interaction and manipulation. Precision in specifying these coordinates is crucial for achieving a coherent and appealing visual experience, as any error in placement can result in incorrect representation of graphical elements. Additionally, screen coordinates are used in input event detection, such as mouse clicks or touches on touch screens, making them a key component in the development of interactive applications.
