👉 Pixel math is the process of calculating the exact values of pixels on a digital display, like a monitor or TV screen, to render images and videos. It involves converting mathematical coordinates from the screen's internal space (typically using a coordinate system like UCS or CRTS) into pixel coordinates that correspond to the physical pixels on the screen. This is done through transformations, such as scaling, rotation, and translation, to map the desired image or video onto the screen's pixel grid. The process ensures that each pixel receives the correct color and brightness, resulting in accurate visual representation. Pixel math is crucial for maintaining image quality, especially when scaling or cropping content, as it preserves the original pixel data and avoids blurring or distortion.
