             Summary: Artifact in rounded border
                 Key: FOP-3286
                 URL: https://issues.apache.org/jira/browse/FOP-3286
             Project: FOP
          Issue Type: Bug
          Components: unqualified
    Affects Versions: 2.11, 2.10, 2.9, 2.8
            Reporter: Jiri Kunhart
         Attachments: artifact.jpg, rounded-corners4.fo, rounded-corners4.pdf

When drawing rounded corners of a rectangle using the FOP algorithm, an artifact appears at the junction of a straight and curved contour line: a small "tooth" in the contour. This defect occurs because the parametric angle or degree size does not smoothly correspond to the curvature of the ellipse in a given quadrant, causing one segment to deviate inward or outward. As a result, the corner is not perfectly smooth, and a visible notch (tooth) appears on the drawn edge.
