What characteristic of Clone Aligned allows it to sample pixels continuously?

The characteristic that allows Clone Aligned to sample pixels continuously is that it samples pixels without losing the current sampling point. This means that once a sampling point is established, the user can continue to paint with the cloned material without having to resample each time. The alignment feature maintains that reference point as the user moves the brush across the canvas, providing a seamless flow in their design work.

This behavior is particularly useful in design applications, where maintaining a consistent replication of texture or detail is crucial. It enhances efficiency since the user does not need to keep clicking to reset the sampling point, allowing for quicker editing and a more fluid creative process.

Other options present limitations or behaviors that are not applicable to the way Clone Aligned functions. For instance, the idea that it requires the mouse button to be held continuously does not accurately represent the functionality of Clone Aligned; it operates independently of whether the mouse button is constantly pressed or not. Similarly, the options regarding losing the current sampling point and restrictions to edge copying do not reflect how Clone Aligned works, detracting from its primary advantage of continuous sampling.
