Abstract: A method for filling closed regions in a drawing using a region filling tool that may appear as a paint bucket. Rather than independently selecting regions to fill or filling based on style-by-layer techniques, the user selects a seed region such that other regions of the drawing are filled if parameters of the other regions match the parameters of the seed region. Matching criteria parameters may include an exact match parameter, a shape matching parameter, a layer matching parameter, and a line weight matching parameter. The parameters may be used alone or in conjunction with other parameters. In this manner, multiple regions in the drawing that are similar to the seed region may be filled using one interaction with the region filling tool. This approach allows the user to more efficiently and intuitively fill regions in the drawing.

Abstract: A method for filling closed regions in a drawing using a region filling tool. Rather than selecting individual regions to fill, or filling based on style-by-layer techniques, the user creates a path or an area boundary to identify the regions to be filled. A graphics application may then fill each region that intersects the path or area boundary with a selected color or graphical style. In this manner, multiple regions in the drawing may be identified using one interaction with the region filling tool, allowing the user to more efficiently and intuitively fill regions in the drawing with the selected color or graphical style.

Abstract: A method for generating a scale-dependent rendering of natural media styles in a vector-based graphics application is disclosed. A vector-based graphics drawing may be resized such that certain scale-dependent parameters are scaled proportionately, while other scale-independent parameters are not scaled. The result of such resizing is a scaled rendering of the vector-based graphics drawing that closely resemble hand drawn images created using natural media materials.

Abstract: Embodiments of the invention provide techniques for generating displays of vector drawing elements that have the appearance of being hand drawn using traditional media materials, such as a pencil. Multiple pencil strokes to be rendered on top of each other and the structure of the simulated paper surface remains constant, generating a realistic appearance for multiple rendered pencil strokes. A variety of physical characteristics of pencils and paper surfaces may be specified, and a convincing appearance may be achieved by modeling these parameters in software, and speed may be realized by rendering the pencil effect using a shader program executed on graphics hardware.

Abstract: Embodiments of the invention provide an auto layer sorting feature for a computer aided drawing (CAD) application where drawing elements are sorted into different drawing layers based on the graphic style associated with each individual drawing element. Objects added to the drawing may be automatically associated with a layer such that all objects on the layer have the same graphic style. If the user changes the properties of a given graphics style associated with one of the auto-sort layers, the updated style may be applied to each objects on that layer.
