Presentation attribute on the outermost svg element. Otherwise, the initial viewport's height must be the value of the height Positioning properties must establish the viewport's height Sufficient to establish the height of the viewport, then these Specified on the referencing element or on the Under these conditions, the viewport's width must be established via the The containing document's outermost svg element that are sufficient Specified on the referencing element (e.g., and there are CSS-compatible positioning properties.and the referencing element or containing document is.the SVG content is a separately stored resource that isĮmbedded by reference (such as the ‘object’ element in HTML), or the SVGĬontent is embedded inline within a containing document.Presentation attribute on the outermost svg element, unless the The initial viewport's width, must be the value of the width Translate( translate-x, translate-y) scale( scale-x, scale-y). The transform applied to content contained by the element is given by ( e-height - vb-height * scale-y) to translate-y. ( e-height - vb-height * scale-y) / 2 to translate-y. ( e-width - vb-width * scale-x) to translate-x. ( e-width - vb-width * scale-x) / 2 to translate-x. Initialize translate-y to e-y - ( vb-y * scale-y).Initialize translate-x to e-x - ( vb-x * scale-x).Set the smaller of scale-x and scale-y to the larger. Otherwise, if align is not 'none' and meetOrSlice is 'slice',.The larger of scale-x and scale-y to the smaller. If align is not 'none' and meetOrSlice is 'meet', set.Initialize scale-y to e-height/ vb-height.Initialize scale-x to e-width/ vb-width.If preserveAspectRatio is not defined or if meetOrSlice is missing from this value. Let meetOrSlice be the meetOrSlice value of preserveAspectRatio, or 'meet'.Let align be the align value of preserveAspectRatio, or 'xMidYMid' if.The position and size of the element respectively. The min-x, min-y, width and height values of the viewBox attribute respectively. The position and size of the element on which the viewBox attribute is defined,Īnd the value of the preserveAspectRatio attribute on that element into a translation andĪ scale that is applied to content contained by the element. This process converts the min-x, min-y, width and height values of a viewBox attribute, Computing the equivalent transform of an SVG viewport The viewport coordinate system relative to the parent element's user coordinate system.Ībstractly, all SVG viewports are embedded in theĪ drawing region that is infinitely large in all relevant dimensions. However, a transform property on an SVG viewport's element will modify Seeīy default, a nested SVG viewport's viewport coordinate system is equivalent to the localĬoordinate system of the parent element, translated by the origin of the SVG viewport'sĮlement. 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 Every SVG viewport defines a drawing region characterized by a size
