![]() Point is inside if even, the point is outside. Path segments from the given shape that the ray crosses. Draw a ray from the point to infinity in any direction and counting the number of The following drawing illustrates the nonzero rule:Įvenodd The following algorithm, or any other that gives the same result, must be used toĭetermine the "insideness" of a point on the canvas. Result is zero then the point is outside the path. Path segment crosses the ray from right to left. Starting with a count of zero, add oneĮach time a path segment crosses the ray from left to right and subtract one each time a Where a segment of the shape crosses the ray. Draw a ray from the point to infinity in any direction and then examine the places Inside of a shape is determined: nonzero The following algorithm, or any other that gives the same result, must be used toĭetermine the "insideness" of a point on the canvas. The 'fill-rule' property provides two options for how the Intersects itself or where one subpath encloses another, the interpretation of "inside" is For a simple, non-intersecting path, it is intuitivelyĬlear what region lies "inside" however, for a more complex path, such as a path that The 'fill-rule' property indicates the algorithm which must be used to determine what parts of the canvas are included inside the shape. Thus, fill operations apply to both open subpaths within 'path' elements (i.e., subpaths without a closepath command) and 'polyline' elements. "closepath" command were added to the path to connect the last point of the subpath with Open subpaths must be filled by performing the fill operation as if an additional The zero-width geometric outline of a shape must be included in the area to Toĭetermine the inside of the shape, all subpaths must be considered, and the interior shallīe determined according to the rules associated with the current value of the 'fill-rule' property. The area to be painted shall consist of any areas inside the outline of the shape. The 'fill' property specifies that the interior of the given graphical element must be painted. "none", system paint, specified value or absolute A system paint server 11.3 Fill properties Is a non-local IRI reference and the viewer does not support it), then the fallback value (if specified) is used otherwise it must be treated as if none was specified. Object that doesn't exist or the object is not a valid paint server or it If the IRI reference is invalid (for example, it points to an ![]() SVG Tiny 1.2 user agents are only required to support local IRI references. Server (e.g., a gradient or 'solidColor') that shall be used to paint the current object. The fragment identifier of the provides a link to the paint The specifies a paint server such as a gradient. the explicit color (in the sRGB color space ). So that your SVG text will draw in the same color. Property and then pass that style to the SVG user agent This mechanism allows you to defineĪ style in your HTML which sets the 'color' This mechanism is provided to facilitate sharing of color attributesīetween parent grammars such as other (non-SVG) XML. currentColor Indicates that painting shall be done using the color specified by the current None Indicates that no paint shall be applied. Gradients and colors are just specific types of paint servers. Paint servers are specified using a local IRI reference SVG uses the general notion of a paint server. a single color, possibly with some level of transparency.With SVG, you can paint (i.e., fill or stroke) with: FillingĪnd stroking both can be thought of in more general terms as painting Stroked (which means painting along the outline of the object). 11.15.3 Defining gradient stops: the 'stop' elementĬan be filled (which means painting the interior of the object) and.11.12 Object and group opacity: the 'opacity' property.11.11 Inheritance of painting properties.11.10.5 The 'buffered-rendering' property.11.9 Controlling visibility and rendering.11.8 The 'viewport-fill-opacity' property.11.6.1 Compositing the currentColor value.11 Painting: Filling, Stroking, Colors and Paint Servers Contents
