How the Delete Anchor Point Tool Alters Paths in Photoshop

The Delete Anchor Point Tool in Adobe Photoshop modifies existing vector paths by removing specific anchor points while preserving the continuous structure of the path. Unlike standard deletion methods that split or open a vector contour, this tool automatically recalculates the segment between the remaining adjacent points. Understanding how this tool functions is essential for simplifying vector shapes, smoothing out jagged curves, and optimizing vector masks without disrupting the integrity of your artwork.

Path Continuity and Auto-Reconnection

When you select an anchor point with the standard Direct Selection Tool and press the Delete or Backspace key, Photoshop deletes both the point and the path segments attached to it, leaving an open or split path.

The Delete Anchor Point Tool behaves differently:

• Preserves Closed Paths: When you click an anchor point on a closed shape (like a polygon or circle), the tool removes that point and immediately bridges the gap by drawing a new segment between the two adjacent anchor points. The shape remains closed.
• Shortens Open Paths: If used on an interior point of an open path, the line remains unbroken and bridges the surrounding points. If used on a terminal endpoint, the path simply ends at the preceding anchor point without deleting the rest of the line.

Reshaping Curves and Bézier Handle Recalculation

Removing an anchor point changes how the curve bends between the remaining points:

• Segment Merging: The two path segments that previously met at the deleted point are merged into a single segment.
• Curve Adjustment: Photoshop redistributes the curve based on the direction handles of the remaining neighboring points. Because the control point that previously defined the curvature at the deleted location is gone, the shape will flatten or stretch between the remaining points.
• Smooth vs. Corner Points: Deleting a corner point turns an angular transition into a direct connection between the adjacent points. Deleting a smooth point typically causes the curve to become broader or less defined, requiring manual adjustment of the adjacent handles to restore the desired shape.

Path Simplification and Optimization

A primary purpose of altering paths with this tool is vector optimization:

• Smoothing Jaggies: Paths generated by auto-tracing or the "Make Work Path" command from a selection often contain an excessive number of points. Removing unnecessary points eliminates micro-bumps and creates clean, sweeping curves.
• Resource Efficiency: Shapes with fewer anchor points render faster, create smaller file sizes, and are significantly easier to manipulate later using the Pen or Direct Selection tools.
