EDITING BEZIER PATCH BY SELECTING MULTIPLE ANCHOR POINTS

Abstract:

Techniques are disclosed for deforming an image using Bezier transformation. The image is divided in a plurality of sections. Each section represents a corresponding Bezier patch. Each section comprises a multiple control points for Bezier transformation, with corner control points of the sections forming anchor points. The deformation of the image is performed by selecting multiple anchor points, and interacting with the selected anchor points. A bounding box that includes the selected anchor points is displayed. Translating, rotating, and/or scaling the selected anchor points based on user input relative to the bounding box results in corresponding Bezier transformation of portion of the image within the bounding box. Thus, instead of having to interact with one control point at a time to deform the image, the desired deformation is achieved by selecting multiple anchor points, and applying the Bezier deformation to the whole bounding box defined by the selected anchor points.
