What effect is used to create a pucker effect on an object?

The pucker effect is specifically designed to modify the shape of an object by making it appear to contract, which is exactly what the "Pucker and Bloat" effect does in Adobe Illustrator. This effect allows the user to select an object and apply a distortion that compresses the edges inward toward the center, creating a visually compelling look that can add depth and interest to a design.

Using the "Distort" category, this effect provides access to a range of parameters that allow fine-tuning of the pucker amount, enabling users to achieve the desired intensity of the effect. This capability is especially valuable for creating dynamic graphics, enhancing illustrations, or manipulating shapes for artistic purposes.

The other options do not provide the same functionality. Transform effects focus on reshaping and repositioning objects without the specific intent of creating a pucker or bloat effect. Simplifying paths can streamline complex shapes but does not alter their appearance in a pucker-like manner. Sharpening filters generally relate to increasing the clarity of an image rather than distorting its shape.
