What is the function of the stamp tool in animation?

The function of the stamp tool in animation is to copy pixel values from one location and at a specific moment in time to another. This tool is particularly useful when animating complex visuals or adjusting elements within an animation. By enabling artists to replicate specific details or textures from one frame to another, it streamlines the animation process, making it more efficient and allowing for greater precision in the final visual output.

In contrast, options that mention aligning layers, creating holes for visibility, or transforming shapes discuss other tools or functions within the animation software, which are not directly related to the specific purpose of the stamp tool. Aligning layers typically involves positioning and organizing elements on the canvas, creating visibility holes pertains to mask layers, and transforming shapes relates to modifying the physical attributes of shapes or objects. Each of these functionalities serves different purposes and will not achieve the same result as the stamp tool, which focuses on the duplication of pixels.
