Abstract: In implementations of systems and procedures for generating surrogate curvatures for assisted vector drawings, a computing device implements acquisition of a target vector curve and compares a curvature of the target vector curve to a curvature of a reference vector curve. The computing device determines whether the curvature of the target vector curve is within a threshold tolerance of the curvature of the reference vector curve. An edited curvature of the targeted vector curve is generated based on the curvature of the reference vector curve.

Abstract: Methods and systems are provided for automated inference and evaluation of design relations for elements of a design. In embodiments described herein, a change, related to a type of design relation, is received to an element of a plurality of elements of a design. A corresponding type of design relation between the element and a different element of the plurality of elements is determined from a knowledge graph based on the type of design relation related to the change. A corresponding change is automatically applied to the different element based on the corresponding type of design relation between the element and the different element.

Abstract: A digital image radial pattern decoding system is described. In one example, an unfolded digital image is formed by the radial pattern decoding system by unfolding a radial pattern in a digital image. An inflated digital image is then generated by the radial pattern decoding system by upsampling the unfolded radial pattern. A grid pattern is determined by the radial pattern decoding system based on the inflated digital image. A radial pattern cell is then generated based on a reverse transform of the grid pattern. A visual pattern is generated by the radial pattern decoding system based on the radial pattern cell.

Abstract: The technology described herein is directed to a Bezier manipulation tool that facilitates a handle-movement paradigm for cohesive manipulation of a selected group of Bezier handles. In some implementations, the Bezier manipulation tool manipulates a selected group of Bezier handles by collectively selecting and synchronously (or concurrently) manipulating multiple handles. For example, when the Bezier manipulation tool detects a user-initiated manipulation of a reference handle of a selected group of Bezier handles, angular and radial length movements of the reference handle occurring as a result of the user-initiated manipulation are calculated relative to an anchor point associated with the reference handle. The Bezier manipulation tool cohesively manipulates other Bezier handles of the selected group of Bezier handles in accordance with the angular and radial length movements of the reference handle, e.g. {delta-theta, delta-r}, concurrent with the user-initiated manipulation of the reference handle.

Abstract: Vector object stylization techniques from raster objects are described that support editing of vector objects in a manner that maintains an underlying mathematical representation of object. A raster object, for instance, is generated from an edited version of an output of a vector object. This raster object, along with the vector object are received as inputs by a vector conversion system. These inputs are utilized by the vector conversion system to generate a stylized vector object having a visual appearance that mimics and simulates a visual appearance of the raster object. As a result, the stylized vector object provides a mathematical representation of the raster object.

Methods of forming a PVD AlN buffer for GaN-based optoelectronic and electronic devices in an oxygen controlled manner are also described. In an example, a method of forming an aluminum nitride (AlN) buffer layer for GaN-based optoelectronic or electronic devices involves reactive sputtering an AlN layer above a substrate, the reactive sputtering involving reacting an aluminum-containing target housed in a physical vapor deposition (PVD) chamber with a nitrogen-containing gas or a plasma based on a nitrogen-containing gas.

Abstract: A graphics processing system generates and employs an affine transformation matrix of transformations for creation of computer graphics replications. The affine transformation matrix encapsulates transformations to the base art to create a replication of a computer graphic. For given transformations, the graphics processing system identifies operations and operation configuration data relating to each operation. For each operation, the graphics processing system generates coefficients for the affine transformation matrix. The affine transformation matrix is multiplied with the base art to generate the repetition. In some configurations, each repetition may require more than one affine transformation matrix to achieve the desired repetition. The order of application of affine transformation matrices to the base art is also modified depending on order of operations to be applied to the base art. A prior repetition may serve as base art for another level of repetition.

Abstract: A digital medium environment is described to improve creation and rasterization of a shape through pixel alignment. In one example, a pixel alignment system is implemented at least partially in hardware of a computing device. The pixel alignment system receives an input that specifies a geometry, a stroke setting, and a location that serves as a basis to position the shape. The pixel alignment system then snaps the location as specified by the at least one input to a snapped location based on a pixel grid. The snapped location based on the geometry, the stroke setting, and the location as specified by the input. A rasterization module is then employed to rasterize the shape as pixels based on the snapped location.

Abstract: Shape joining based on proximity is leveraged in a digital medium environment. For instance, an automated system is provided to detect shape proximity and to implement automated shape joining when shapes are detected within a threshold proximity. In an example implementation, when a first shape is detected within a threshold proximity to a second shape, the described processes automatically calculate a join geometry for connecting the shapes, and automatically apply the join geometry to join the shapes and generate a joined shape. Thus, utilizing the described techniques, shapes of differing geometries can be automatically joined. Further, joined shapes can be edited and transformed in different ways.

Abstract: Symmetry axis digital content generation techniques and systems are described that support diverse types of art included in the digital content and may do so in real time as part of creating and editing symmetry art. A symmetry art generation system determines a portion of the source object, defined as encompassed by a path, that is to be reflected to generate the reflected object. As a result, the symmetry art generation system involves a reduced number of low-cost computations in order to calculate the path. The path also defines a minimized area defining a relevant portion of the source object to be reflected and thus reduces computational resource consumption by a computing device that implements these techniques and works for a wide range of art types.
