A radial color gradient. A radial gradient is specified as a circle that has one color at the edge and another at the center. Colors are calculated by linear interpolation based on distance from the center. This can be used to approximate the diffuse reflection of light from a point source by a sphere.

Description: Trying to figure out, why the balls in File:Composition of 5-element permutations; R arrows (right).svg are rendered more shiny in the PNG than they are in the SVG
The gradient of F is then normal to the hypersurface. Similarly, an affine algebraic hypersurface may be defined by an equation F(x 1, ..., x n) = 0, where F is a polynomial. The gradient of F is zero at a singular point of the hypersurface (this is the definition of a singular point). At a non-singular point, it is a nonzero normal vector.
The pixels with the largest gradient values in the direction of the gradient become edge pixels, and edges may be traced in the direction perpendicular to the gradient direction. One example of an edge detection algorithm that uses gradients is the Canny edge detector. Image gradients can also be used for robust feature and texture matching.
Color gradients can be linear or radial (circular), and can involve any number of colors as well as repeats. Opacity gradients can also be specified. Patterns are based on predefined raster or vector graphic objects, which can be repeated in x and y directions. Gradients and patterns can be animated and scripted. [39]
Boxy SVG can also open SVG files authored with Inkscape and Adobe Illustrator, all software-specific elements and attributes will be dropped. The application is based on the Electron framework and thus supports the same subset of the SVG format as Chromium-based web browsers such as Google Chrome, Microsoft Edge , and Opera .
