A bitmap image is defined by a grid of pixels, where each pixel represents a single point in the image. This structure allows for intricate details and a wide range of colors, making bitmap images ideal for representing complex visuals like photographs. Bitmap images are resolution-dependent, meaning that their quality is directly affected by their pixel density—if you enlarge a bitmap image too much, it can appear pixelated or blurry, as the individual pixels become visible.

In contrast, vector images utilize mathematical formulas to define shapes and lines, allowing them to be resized without loss of quality. Sprites are typically bitmap images used in gaming and animations, but they are not defined inherently by the grid of pixels; rather, they are more about the application in motion graphics. Texture maps apply bitmap images to 3D models, serving as the surface detail in rendering, but they are also not defined as a standalone component by pixel grids, but rather how they are utilized in graphics.
