    Gradient Descriptor

    Gradient descriptor consists of <type>(<coords>)<colors>. Type -could be linear or radial, which presented as letter “L” or “R”. Any -type could be absolute or relative, absolute gradient take it coords -relative to the SVG surface, while relative takes them relative to -the bounding box of the element it applied to. For absolute -coordinates you specify type as an upper case letter (“L” or “R”). -For relative use low case letter (“l” or “r”). Coordinates specify -vector of gradient for linear as x1, y1, x2, y2. For radial as cx, -cy, r and optional fx, fy. Colors are list of dash separated colors. -Optionally color could have offset after colon. +

    Gradient Descriptor

    The gradient descriptor is an expression formatted as +follows: <type>(<coords>)<colors>. The <type> can be +either linear or radial. The uppercase L or R letters +indicate absolute coordinates offset from the SVG surface. +Lowercase l or r letters indicate coordinates +calculated relative to the element to which the gradient is +applied. Coordinates specify a linear gradient vector as +x1, y1, x2, y2, or a radial gradient as cx, cy, +r and optional fx, fy specifying a focal point away +from the center of the circle. Specify <colors> as a list +of dash-separated CSS color values. Each color may be +followed by a custom offset value, separated with a colon +character.
