Ways to ensure that an svg image is perfectly sized to its parent container

I'm exploring the svg <image> tag for the first time. I've decided to use this tag to apply a gray filter on an image (thanks, IE).

Check out my HTML code below:

<div class="container">
  <div class="item">
    <svg version="1.1" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg">
        <image xlink:href="https://dummyimage.com/400x400/000/00ffd5.png" />
    </svg>
  </div>
</div>

Here's the corresponding scss code:

.item {
  position: relative;
  width: 20%;
  height: 220px;

  background-color: blue;
}

svg {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;

  image {
    width: 100%;
    height: 100%;
  }
}

I am aiming to make the image fit the parent container, similar to using background: cover in css. Any suggestions?

The blue background is set for the div.item.

Answer №1

Include attributes width="100%" and height="100%".
Integrate preserveAspectRatio ¹ with a value of none².

none allows non-uniform scaling, adjusting the graphic content as needed to fit the specified element's boundaries precisely to the viewport rectangle.
Note: if <align> is set to none, then the optional <meetOrSlice> parameter is disregarded.

jsFiddle - compatibility tested on Chrome, FF, and IE11

.item { position: relative; width: 20%; height: 220px; background-color: blue; }
svg { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

<div class="item">
  <svg id="theSVG" version="1.1" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg">
      <image width="100%" height="100%" xlink:href="//dummyimage.com/400x400/000/00ffd5.png" preserveAspectRatio="none" />
    </svg>
</div>

Notes:

The suggestion to use the preserveAspectRatio attribute was initially provided in an earlier answer - although the specific user has been forgotten, credit goes out to them for their contribution - that answer included
```
preserveAspectRatio="xMidYMid slice"
```
, but lacked the inclusion of width="100%" height="100%", except within CSS which, unfortunately, does not fully resolve the issue [partially, because if you resize the view larger the blue background will start to show up] in Chrome, as mentioned in @Paul LeBeau's response. The functionality of this solution is illustrated in this jsFiddle Demo.
none does not enforce uniform scaling, potentially causing distortion or stretching of images for alignment purposes. While it may not make a difference in the present scenario, if maintaining aspect ratio becomes essential, alternatives like other options such as Min, Mid, and Max for x or y could be considered alongside slice, excluding meet.

Answer №2

To ensure proper scaling of your SVG, make sure to specify an appropriate viewBox attribute. Additionally, set the preserveAspectRatio attribute to use the slice option instead of the default meet. For example:

preserveAspectRatio="xMidYMid slice"

This setting is similar to CSS's background-size: cover.

It's important to note that specifying the width and height of the <image> using CSS will only be effective in Chrome at the moment. To ensure compatibility with other browsers, you should define these dimensions directly within the SVG.

.item {
  position: relative;
  width: 20%;
  height: 220px;

  background-color: blue;
}

svg {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}

<div class="container">
  <div class="item">
    <svg viewBox="0 0 400 400" preserveAspectRatio="xMidYMid slice">
        <image xlink:href="https://dummyimage.com/400x400/000/00ffd5.png"
               width="400" height="400"/>
    </svg>
  </div>

If you're looking for an alternative to using the image tab, here is a CSS solution I came up with:

.item-image{
 width:100%;
 height:100%;
 background: url(https://dummyimage.com/400x400/000/00ffd5.png) center;
background-size: 100% 100% ;
}

Make sure to create a div with the item-image class and place it between svg tags.

Dealing with the same issue? Consider opting out of using the image sourcegraphic and instead utilize a background image combined with an SVG filter for better results.

If you are aiming for a cover fit, incorporate a background image as usual and then apply a filter to the element through referencing an SVG filter.

For instance:

.bg_img {
    -webkit-filter: url(#distort_slider_filter);
    filter: url(#distort_slider_filter);
}
