Svg viewbox preserveaspectratio. The preserveAspectRatio Attribute By default, SVG content with a viewBox is scaled to maintain the aspect ratio, and if the aspect ratios of the sides of the viewport and viewbox do not match, margins will appear around the content: SVG loaders. 'svg' => array( 'viewbox' => true, // viewBox 'preserveaspectratio' => true, // preserveAspectRatio ), 'lineargradient' => array( // linearGradient 'gradientunits' => true, // gradientUnits 'gradienttransform' => true, // gradientTransform 'spreadmethod' => true, // spreadMethod ), ); ``` 52. I want to fill a viewport with an svg, and add a fill to a path in this svg. Jan 3, 2026 · Master SVG viewBox with this complete guide. g. SVG allows control over how the element is scaled within its viewBox with the “preserveAspectRatio” attribute. For example, the SVG below defines a viewpoint with width 100 and height 100. 阅读目录 一：理解viewport 二：理解viewBox 三：理解 preserveAspectRatio 回到顶部 一：理解viewport 该属性表示的是SVG可见区域的大小。或者也可以叫画布的大小。就好比我们的电脑屏幕，我们只能看到我们电脑屏幕的可视区里面的内容，但是看不到电脑屏幕之外的内容 SVG PreserveAspectRatio SVG PreserveAspectRatio Introduction This chapter demonstrates about the SVG preserveAspectRatio, which is used to display the canvas in a browser when the viewBox and viewport have the different aspect ratios, following are the concepts covered in this chapter. It is viewBox which tells the renderer how big the contents of your SVG are, so it knows how much to scale by. The preserveAspectRatio attribute on SVG elements can be used to prevent your graphics deforming when scaled. by default, JFreeSVG uses a fast conversion of numerical values to strings for the SVG output (the 'RyuDouble' implementation). The preserveAspectRatio read-only property of the SVGSVGElement interface reflects the preserveAspectRatio attribute of the given element. SVG can be scaled along with the parent container without changing the internal coordinates. Unlike many other image formats, the SVG format is text-based. Think of it as a two-part instruction: first, you specify the alignment (where to position the scaled content), and second, you define the scaling behavior (whether to maintain proportions or stretch to fill). I hope you found this article useful in understanding the SVG viewport, viewBox, and preserveAspectRatio concepts. The preserveAspectRatio attribute determines how an SVG element scales when its viewBox dimensions don’t match the viewport dimensions. This opens up how we c HTML svg preserveAspectRatio. Popular topics preserveAspectRatio is the partner in crime of the SVG viewBox. What are SVGs? Scalable Vector Graphics (SVG) are a method computers use to describe an image. An open framework for the web that enables Real-Time Communications (RTC) capabilities in the browser. Preserving Aspect Ratio If the viewport and the view box does not have the same aspect ratio (width-to-height ratio), you need to specify how the SVG viewer (e. The preserveAspectRatio attribute might seem like a small detail, but mastering it gives you precise control over how your graphics adapt to different screen sizes and container dimensions. SVG viewBox属性和preserveAspectRatio属性 viewBox属性 viewBox属性允许指定一个给定的一组图形伸展以适应特定的容器元素。 viewBox属性的值是一个包含4个参数的列表 min-x, min-y, width and height， 以 空格 或者 逗号 分隔开。 To make it work on IE 9 I had to add the viewBox="0 0 580 220" and preserveAspectRatio="xMidYMid meet" and remove the width="580" and height="220" SVG properties. GitHub Gist: instantly share code, notes, and snippets. Shipping web projects should be fast, easy, and low risk. 整个 SVG 的 viewbox 在视图范围内是可见的 尽可能的放大 SVG 的 viewbox，同时仍然满足其他的条件。 在这种情况下，如果图形的宽高比和视图窗口不匹配，则某些视图将会超出 viewbox 范围（即 SVG 的 viewbox 视图将会比可视窗口小）。 slice - 图形将缩放到： « SVG Attribute reference home In some cases, typically when using the viewBox attribute, it is desirable that the graphics stretch to fit non-uniformly to take up the entire viewport. I have a large svg image and I want it scales well in different scenarios (see snippet). SVG loaders. “preserveAspectRatio” allows you to control how elements are scaled within the viewBox with “align” and allows you to control how the viewBox is framed within the viewport with “meetOrSlice”. Each symbol comes with its own viewBox and preserveAspectRatio attributes, defining the space and boundaries of this mini artboard. You’ll learn about the meet and slice values as well as the Min/Max/Mid values. Jan 14, 2026 · If preserveAspectRatio is meet, the browser picks the smaller scale (1. The resulting viewBox is a rectangle in user space mapped to the bounds of the viewport of an SVG element (not the browser viewport). rule-of-thirds bookmarklet. 2) to ensure everything fits. The default behavior is meet which stretches the content in both the x and y dimension until it fills either the width or height of the viewBox. Surge is static web publishing for Front-End Developers, right from the CLI. It allows us to integrate SVGs with other Web standards such as HTML, CSS and JavaScript Jul 10, 2019 · Learn how to scale your SVG images using the preserveAspectRatio attribute. To use an SVG symbol, you first define it with a <symbol> element, giving it a unique id. The default value is xMidYMid, which maintains the aspect ratio and centers the path inside the SVG container: <!-- when not included `preserveAspectRatio` defaults to `xMidYMid` --> The first SVG have the width set to 500, height to 100 and the viewBox attribute set to 0 0 500 10. This attribute only works if the <svg> element also has a viewBox. The svg采用类似canvas的坐标系统，以左上角为0，0原点，从左往右计算x值，从上到下计算y值。这个和HTML中标示位置的方法相同。我们来看一个例子 Developers love Redis. 文章详细解释了SVG中viewport、viewBox和preserveAspectRatio的概念及其应用，帮助读者更好地理解和使用这些属性。 Das preserveAspectRatio-Attribut gibt an, wie ein Element mit einem viewBox und einem bestimmten Seitenverhältnis in einen Anzeigebereich mit einem anderen Seitenverhältnis passen muss. This only works if the viewBox attribute is present. CSDN问答为您找到SVG的viewBox属性如何正确设置宽高比与缩放关系？相关问题答案，如果想了解更多关于SVG的viewBox属性如何正确设置宽高比与缩放关系？ 青少年编程 技术问题等相关问答，请访问CSDN问答。 Contribute to kowshik44/portfolio-website development by creating an account on GitHub. preserveAspectRatio The preserveAspectRatio attribute indicates how an element with a viewBox providing a given aspect ratio must fit into a viewport with a different aspect ratio. The "preserveAspectRatio" Lesson is part of the full, SVG Essentials & Animation, v2 course featured in this preview video. If you’d like to learn more about SVG coordinate systems, like nesting coordinate systems, establishing new ones, and transformations in SVG, stay tuned for the remaining parts of this series. 文章详细解释了SVG中viewport、viewBox和preserveAspectRatio的概念及其应用，帮助读者更好地理解和使用这些属性。 The preserveAspectRatio attribute, as the name implies, determines if the SVG should scale when the aspect ratio defined in viewBox doesn’t match the ratio in the parent container. Convert SVG vector graphics to PNG raster images online. . A quick example that makes a call to scale the svg container prior to a transition that will scale some inner element up. When I set preserveAspectRatio="xMinYMin slice" to the image pattern, it will preserve it's aspect ratio nicely, but the Learn what SVG viewBox and preserveAspectRatio are, how they work, and how to use them to create responsive graphics with HTML. I break it all down for you with loads of visuals and demos. Just like any other image format. It defines how the SVG element's content should be scaled to fit the given space, preserving its aspect ratio. preserveAspectRatio is an attribute that indicates whether the image should be scaled uniformly. In other cases, it is desirable that uniform scaling be used for the purposes of preserving the aspect ratio of the graphics. That means that along the y-axis every coordinate unit will correspond to 10 pixels, but along the x-axis every coordinate unit will only correspond to 1 pixel. Preserve transparency and quality with browser-based processing. When an SVG contains a viewBox attribute (often in combination with a preserveAspectRatio attribute), a transform stretches or resizes the SVG viewport to fit a particular container element. HTML svg preserveAspectRatio attribute. preserveAspectRatio preserveAspectRatio 属性は、指定された アスペクト比 を提供するビューボックスを持つ要素が、異なるアスペクト比を持つビューポートにどのように収まるべきかを示します。 SVG 画像のアスペクト比は viewBox 属性によって定義されます。 SVG PreserveAspectRatio SVG PreserveAspectRatio Introduction This chapter demonstrates about the SVG preserveAspectRatio, which is used to display the canvas in a browser when the viewBox and viewport have the different aspect ratios, following are the concepts covered in this chapter. If you do not understand the viewBox just yet, then go check out my other article here explaining it. Because the aspect ratio of an SVG image is defined by the viewBox attribute, if this attribute isn't set, the preserveAspectRatio attribute has no effect (with one exception, the <image> element, as described below). The preserveAspectRatio read-only property of the SVGViewElement interface reflects the preserveAspectRatio attribute of the given <view> element. I recently wrote a post on understanding SVG viewport and viewBox and figured this would be the perfect follow-up topic to quickly dig a little deeper. preserveAspectRatio does nothing if your SVG doesn't have a viewBox. That means the drawing is 120×120 inside a 300×120 box, and the extra horizontal space is centered (unless you change alignment). Learn SVG - preserveAspectRatio - meet and slice attributes The preserveAspectRatio attribute has an optional parameter: meet | slice. The alternative - slice preserves the aspect ratio of the content but scales up the graphic until it fills both the The preserveAspectRatio attribute indicates how an element with a viewBox providing a given aspect ratio must fit into a viewport with a different aspect ratio. If you prefer a different approach (for example, controlling the number of decimal places in the output to reduce the file size) you can set your own functions for converting numerical values - see the setGeomDoubleConverter (DoubleFunction) and viewBox and preserveAspectRatio The attribute viewBox specifies viewpoint dimension. Here's what you'd learn in this lesson: Once you add a viewBox to your <svg> (and editors like Inkscape and Illustrator will add it by default), you can use that SVG file as an image, or as inline SVG code, and it will scale perfectly to fit within whatever size you give it. preserveAspectRatio gives us the ability to tell our graphic how to scale when the aspect ratio of the viewBox and viewPort are different. HTML svg preserveAspectRatio. As given in the examples of the previous post about creating a viewport in SVG, the aspect ratio, or ratio of width to height, of the viewport and the viewBox were the same. the browser) is to display the SVG image. The preserveAspectRatio attribute on an <svg> tag specifies that the svg is scaled uniformly in both the x and y direction. The preserveAspectRatio attribute takes two values separated by a space. It defines how the content within the view should be scaled to fit its viewport while preserving its aspect ratio. More precisely, SVGs are XML-based. For Check the interactive demo out. You do so using the preserveAspectRatio attribute of the <svg< element. Learn how viewBox controls scaling, fix cropping issues, understand preserveAspectRatio, and make your SVGs responsive. The aspect ratio of an SVG image is defined by the viewBox attribute. Syntax preserveAspectRatio="<align> [<meetOrSlice>]" Its value is made of one or two keywords: A required alignment value and an optional "meet or slice" reference as described below: Alignment value The alignment value indicates whether to force uniform scaling and, if so, the alignment method to use in case the aspect ratio of the viewBox doesn't match the aspect ratio of the viewport. preserveAspectRatio is used to control how an SVG is displayed when the viewBox and viewport have different aspect ratios. Jun 23, 2025 · The preserveAspectRatio attribute indicates how an element with a viewBox providing a given aspect ratio must fit into a viewport with a different aspect ratio. This article explains the complexities of SVG viewBox and provides insights for better understanding and usage in web development. In some cases, typically when using the viewBox attribute, the graphics should stretch to fit non-uniformly to take up the entire viewport. This opens up how we can interact with the image. Attribute preserveAspectRatio indicates whether or not to force uniform scaling. Unlock the full potential of the Redis database with Redis Enterprise and start building blazing fast apps. I originally was using the width and height attributes of the svg and was setting these values everytime the L'attribut preserveAspectRatio indique comment un élément est mis à l'échelle lorsque le ratio largeur:hauteur de la viewBox est différent du ratio de la zone d'affichage (défini par les attributs width et height).
