Abstract: Folding avoidance in skeletal stroke application is provided. In some embodiments, folding avoidance in skeletal stroke application includes identifying a destination path for a source artwork and a plurality of ribs extending perpendicularly from the destination path, in which the source artwork is mapped onto the destination path; determining a contiguous region along the destination path including a subset of ribs; in which each of the subset of ribs in the contiguous region crosses another rib in the contiguous region that is not necessarily an adjacent rib; and adjusting each of the subset of ribs in the contiguous region so that each of the ribs no longer crosses another rib in the contiguous region to provide a modified subset of ribs. Accordingly, the source artwork can then be adapted to fit along the destination path using the adjusted ribs.

Abstract: A technique for modifying a stretch of path is disclosed. The technique includes receiving an indication of a drag gesture associated with a designated point on a path, identifying the first path corner or endpoint on either side of the designated point as limit points, defining a smooth stretch of the path as a portion of the path between the limit points, and modifying the smooth stretch of the path based on the drag gesture without modifying portions outside of the smooth stretch.

Abstract: Techniques for assigning a region attribute to a region in a drawing are disclosed. One technique includes editing the drawing to define a current region, associating the current region with a previous region having a previous region attribute, and assigning the previous region attribute to the current region. Another technique includes deriving a previous path attribute and a relation for a previous path, editing the drawing to define a current set of paths having current regions, and assigning the previous path attribute to at least one current region based on the relation of the previous path.

Abstract: Methods and apparatus, including computer program apparatus, implementing techniques for processing digital artwork. In one aspect, the techniques process aggregations of artwork where both the aggregation and at least some of the aggregated artwork have attached styles. The techniques handle various combinations of conditions resulting in applying style elements to the aggregation before or after applying style elements to underlying artwork. In another aspect, the techniques implement editable path objects having multiple attached fills and/or strokes. The techniques provide user interfaces for using the foregoing features.

Abstract: A technique for editing is disclosed. The technique includes generating a path definition for a path, generating a plurality of subpath definitions of subpaths of the path based on an intersection of the path, associating the subpath definitions with the path definition, modifying the intersection of the path using an editing tool, and generating a plurality of modified subpath definitions of subpaths of the path based on the modified intersection of the path.

Abstract: Techniques for assigning a subpath attribute to a subpath in a drawing are disclosed. One technique includes editing the drawing to define a current path having a current subpath, matching a previous vertex in a previous path with a current vertex in the current path, and assigning a current subpath attribute to the current subpath based on the vertex match. Another technique includes editing the drawing to define a current path having a current subpath, comparing the current subpath with a previous subpath having a previous subpath attribute, and assigning a previous subpath attribute to the current subpath based on the comparison.

Abstract: Assigning an attribute is disclosed. Assigning an attribute includes receiving a first region from a first frame, wherein the first region is associated with an attribute, receiving a second region from a second frame, and automatically assigning the attribute to the second region.

Abstract: A computer-implemented method alters component colors of art work associated with a drawing stroke on an electronic document. In one aspect, the invention generates a darkness value for each component color of each original color; generates a new color to substitute for each original color, the component color values of the new color being generated according to the corresponding darkness value and a reference color; and alters the component colors of the art work based on the new color values. In a second aspect, the invention provides a computer-implemented method for altering a component color of art work by mapping the component color to a new color based on a color space associated with the component color and applying the resulting color to components of the art work.

Abstract: A method of blending artwork objects. In the method, user input is received selecting a first parameter setting and a second parameter setting for an effect on an object. The first parameter setting, the second parameter setting and a blend parameter setting are passed to the effect. A third parameter setting is generated in the effect from the first parameter setting, the second parameter setting and the blend parameter setting. The effect is applied to the object with the third parameter setting to generate an rendered version of the object.
