Description

The amp-story animation preset scales the pan effect image. For example, pan-right effect:

The calculateTargetScalingFactor method ensures the image is at least 25% larger than the page; however, the logic is not useful when the image is not full-bleed in the page. For example, a small image in the story page with pan- animation might be scaled to 2x while the expectation is not to scale.

Hope to provide an option such as animation-scale-disabled to disable the scaling.

Alternatives Considered

Use other animation, or create a custom panning animation. Yet to resolve it, providing an option to disable the scaling would help the most.
