Parent of that fragment (whether real or implicit). Process between the SVG document fragment generating the SVG viewport, and the The width, height and origin of SVG viewports is established by a negotiation Units and provide a new reference rectangle for 'fitting' a graphic relative SVG viewports provides an opportunity to redefine the meaning of percentage To the width and height of the nearest ancestral SVG viewport. Percentage units are resolved with reference Child elements of a viewport canįurther modify the user coordinate system, for example by specifying Relative to the viewport coordinate system as described in

Providing a ‘ viewBox’ on a viewport's element transforms the user coordinate system SeeĮstablishing a new SVG viewport for informationĪnd a user coordinate system, initially identical. SVG viewports are only established by elements. Establishing an initial viewport is described in more SVG viewport that establishes a mapping between the coordinate system usedīy the containing environment (for example, CSS pixels in web browsers)Īnd user units. Note that the term SVG viewport is distinct from the (width, height), and an origin, measured in abstract The content of the mask is a single rect element, that is filled with a black-to-white gradient.Every SVG viewport defines a drawing region characterized by a size The latter has the mask attribute pointing to the mask element. You see a green-filled rect at the lowest layer and on top a red-filled rect. Color, opacity and such have no effect as long as they don't let parts vanish completely. Then every part of the target lying in a transparent area of the resulting clipPath's content will not be rendered. For the clipping, every path inside the clipPath is inspected and evaluated together with its stroke properties and transformation. We now have a semicircle without having to deal with arcs in path elements. Since the rectangle covers only the upper half of the circle, the lower half of the circle will vanish: Instead its pixel data will be used to determine, which pixels of the circle 'make it' to the final rendering. Note, that the clipPath element is usually placed in a defs section. This rectangular on its own would paint the upper half of the canvas black. The attribute clip-path references a element with a single rect element.

Centered at (100,100) a circle with radius 100 is painted.
