What is the primary role of pixels in a bitmap image?

The primary role of pixels in a bitmap image is to represent colors and create the image. Each pixel is the smallest unit of a digital image and contains color information. When these pixels are combined in a grid-like structure, they collectively form an entire image. The arrangement and color of each pixel contribute to the overall visual appearance, allowing for detailed and complex imagery to be displayed.

For instance, in a color image, each pixel typically contains data that specifies the intensity of the red, green, and blue (RGB) components. Through the proper arrangement of these colored pixels, a bitmap image can display a wide range of colors and patterns, ensuring that the final representation closely aligns with the intended visual content.
