How does SVG image pattern work with preserving aspect ratio? - css

I have the following svg:
<svg height="100%" width="100%" viewBox="0 0 100 100" preserveAspectRatio="none" style="display: block; position: absolute; top: 0;">
<defs>
<pattern id="img1" patternUnits="objectBoundingBox" width="100%" height="100%">
<image xlink:href="https://media.npr.org/assets/img/2016/06/22/gettyimages-467390112_custom-e8fa0c9a7224b7172555577fde25a08949bde2d2-s900-c85.jpg" x="0" y="-20" width="100" height="100"/>
</pattern>
</defs>
<polygon points="0 100, 50,50 100,100" id="abajo" style="stroke-width:0" fill="url(#img1)"/>
</svg>
It's not working as expected because it enlarge te face of the people on the image as follows:
But it should look like this:
Does having a triangular polygon affects the image? How can I solve it, I need 4 triangle figures with images inside to be clickables.

Well this is working as intended. You specify a pattern whose unit should fill the bounding box of the container, and then specify a 2:1 container - so it stretches the image. There are lots of permutations that preserve the aspect ratio of the image - it depends on exactly what behavior you want.
This is one version that preserves the aspect ratio of the SVG itself even when it's asked to fill a larger space.
<svg height="100%" width="100%" viewBox="0 0 100 100" preserveAspectRatio="xMidYMid slice" style="display: block; position: absolute; top: 0;">
<defs>
<pattern id="img1" patternUnits="objectBoundingBox" width="100%" height="100%">
<image xlink:href="https://media.npr.org/assets/img/2016/06/22/gettyimages-467390112_custom-e8fa0c9a7224b7172555577fde25a08949bde2d2-s900-c85.jpg" x="0" y="-20" width="100" height="100"/>
</pattern>
</defs>
<polygon points="0 100, 50,50 100,100" id="abajo" fill="url(#img1)" />
</svg>
Or if you want to adjust the pattern itself, you can double the height of the pattern and offset it in Y to adjust for the 2:1 ratio of your container:
<svg height="100%" width="100%" viewBox="0 0 100 100" style="display: block; position: absolute; top: 0;">
<defs>
<pattern id="img1" patternUnits="objectBoundingBox" y="-100%" width="100%" height="200%">
<image xlink:href="https://media.npr.org/assets/img/2016/06/22/gettyimages-467390112_custom-e8fa0c9a7224b7172555577fde25a08949bde2d2-s900-c85.jpg" x="0" y="0" width="100" height="100" preserveAspectRatio="xMidYMax meet"/>
</pattern>
</defs>
<polygon points="0 100, 50,50 100,100" id="abajo" fill="url(#img1)" />
</svg>
This is another version that uses a filter to fill in the image.
<svg height="100%" width="100%" viewBox="0 0 100 100" style="display: block; position: absolute; top: 0; background:grey">
<defs>
<filter id="img1" x="0%" y="0%" width="100%" height="100%" >
<feImage xlink:href="https://media.npr.org/assets/img/2016/06/22/gettyimages-467390112_custom-e8fa0c9a7224b7172555577fde25a08949bde2d2-s900-c85.jpg" x="0" y="0" width="100" height="100" preserveAspectRatio="xMidYMax meet"/>
<feComposite operator="in" in2="SourceGraphic"/>
</filter>
</defs>
<polygon points="0 100, 50,50 100,100" id="abajo" filter="url(#img1)" />

How to use SVG clipPath with Pattern via CSS clip-path property?

The initial SVG figure with pattern:
<svg width="200" height="200" viewBox="0 0 100 100">
<defs>
<pattern id="img-dotted-dots" x="0" y="0" height=".08" width="7.69%">
<circle cx="2" cy="2" fill="white" r="0.8"></circle>
</pattern>
<mask id="img-dotted-mask">
<rect width="100" height="100" fill="url(#img-dotted-dots)"></rect>
</mask>
</defs>
<path d="M0 0 H 100 V 100 H 0 Z" mask="url(#img-dotted-mask)" fill="#1063B1"></path>
</svg>
Need to achieve:
One instance of the SVG figure with pattern for refferencing with CSS as clip-path.
I have tried to create SVG clipPath element and bind to CSS clip-path by this way
.figure {
width: 300px;
height: 300px;
clip-path: url(#img-dotted-clip-path);
background-color: #1063B1;
}
<div class="figure"></div>
<svg width="0" height="0" viewBox="0 0 100 100">
<defs>
<clipPath
clipPathUnits="objectBoundingBox"
id="img-dotted-clip-path">
<pattern
patternUnits="objectBoundingBox"
patternContentUnits="objectBoundingBox"
x="0" y="0" height="0.1" width="0.1">
<circle cx="0" cy="0" fill="white" r="0.5"></circle>
</pattern>
</clipPath>
</defs>
</svg>
Nothing happens.
Expected result - the same as the previous snippet.
For comparing:
If I use SVG rect - CSS clip-path works.
If pattern - doesn't
.figure {
width: 300px;
height: 300px;
clip-path: url(#img-dotted-clip-path);
background-color: #1063B1;
}
<div class="figure"></div>
<svg width="0" height="0" viewBox="0 0 100 100">
<defs>
<clipPath
clipPathUnits="objectBoundingBox"
id="img-dotted-clip-path">
<rect width="1" height="1"></rect>
</clipPath>
</defs>
</svg>
The only things that are valid inside a clip path are:
Shape elements (‘circle’, ‘ellipse’, ‘line’, ‘path’, ‘polygon’, ‘polyline’, ‘rect’)
‘text’
‘use’
Plus you can use animation elements etc to animate the clip path. However, only the shapes of those elements are used. Effects such as patterns, filters, etc are ignored.
The only way you could get the effect you want to work as a clipping path would be to add numerous <circle> elements to your <clipPath>.
<clipPath>
<circle>
<circle>
<circle>
<circle>
... etc ...
</clipPath>
But you could use a mask instead. Masks allow patterns.
.figure {
width: 300px;
height: 300px;
-webkit-mask: url(#img-dotted-mask);
mask: url(#img-dotted-mask);
background-color: #1063B1;
}
<p>This only works in Firefox</p>
<div class="figure"></div>
<svg width="0" height="0">
<defs>
<pattern id="img-dotted-pattern"
viewBox="0 0 1 1"
patternUnits="userSpaceOnUse" x="0" y="0" width="20" height="20">
<rect width="1" height="1" fill="black"/>
<circle cx="0.5" cy="0.5" fill="white" r="0.15"></circle>
</pattern>
<mask id="img-dotted-mask">
<rect width="2000" height="2000" fill="url(#img-dotted-pattern)"/>
</mask>
</defs>
</svg>
However inline SVG masks applied to HTML elements, like my example above, only work in Firefox. To get an SVG mask to work in Chrome, you would need to use mask or mask-image with an external or Data URL (as Temani has done in their answer).
You can recreate the same thing using mask combined with radial-gradient
.figure {
width: 300px;
height: 300px;
background:linear-gradient(to right,red,#1063B1);
/*radius here size here*/
-webkit-mask:radial-gradient(3px, #fff 97%,transparent 100%) 0 0/20px 20px;
mask:radial-gradient(3px, #fff 97%,transparent 100%) 0 0/20px 20px;
}
body {
background:#f2f2f2;
}
<div class="figure"></div>
Or consider the SVG inside the mask property. Make sure to escape the # and correctly set the viewbox and width/height to have a perfect repeat
.figure {
width: 300px;
height: 300px;
background:linear-gradient(to right,red,#1063B1);
-webkit-mask:url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="200" height="192" viewBox="0 0 100 90"><defs><pattern id="img-dotted-dots" x="0" y="0" height=".08" width="7.69%"><circle cx="2" cy="2" fill="white" r="0.8"></circle></pattern><mask id="img-dotted-mask"><rect width="100" height="100" fill="url(%23img-dotted-dots)"></rect></mask></defs><path d="M0 0 H 100 V 100 H 0 Z" mask="url(%23img-dotted-mask)" fill="%231063B1"></path></svg>');

}

}

Responsive SVG Mask

I have looked at several other answers on Stack:
Responsive SVG Clip Path or Mask Image
Responsive SVG image mask
But none seem to work for me. I have an SVG mask based on a path. I want it to expand to fill all available space (or contract) whilst keeping the aspect ratio of the path.

The SVG seems to obey the path values no matter what I do. Is there a way to make it expand or contract like an image would?
I've simplified your code in the sense that I'm applying the mask to the image instead of using patterns. Also the mask is the path. I'm not using width="100%" since the width af an svg element will take all the space available i.e 100%.
I would like to understand why you need it height="100%"

Alternatively if you need all those patterns please remove width="100%"for the mask in your code.

SVG circle take all the height preserving aspectratio on any div size

The idea is to draw a circle in SVG that takes the whole height on the parent div whatever the size of the parent div. The width should be somehow ignored.
I've been working a bit with aspect ratio of SVG but this does not really work on all scenarios :
<div style='width:400px;height:100px'>
<svg width="100%" height="100%" viewbox="0 0 200 100" preserveAspectRatio="xMinYMin slice">
<circle cx="50" cy="50" r="40" stroke="black" stroke-width="0" fill="red" />
<text x="100" y="50">Example SVG text 1</text>
</svg>
</div>
With the div width defined with 200px it's working.
Fiddle: https://jsfiddle.net/91sp2j0x/11/
Specifying a value of 50 for the r attribute will allow the nested svg element to maintain a 100% height of its containing (parent) element.

Updated JSFiddle
Is this what you would like to happen? I set the height of the div for each of the divs to different heights, and set the divs to display: inline-block so that the width is not 100%, as divs usually are by default, since they are block elements. That way the height of the SVG will be the height of the div.

<svg height="100%" viewbox="0 0 200 100" preserveAspectRatio="xMinYMin meet">

If i understood right, u want to have the circle with the radius of the height...
I did that successfully like so (if i understood what u asked correctly):
<div style='width:800px;height:120px;'>
<svg viewbox="0 -10 200 140" preserveAspectRatio="xMinYMin slice"> /* just remove the height and the width from the svg, it will take the parameters from the div... */
<circle cx="18%" cy="18%" r="18%" stroke="black" stroke-width="0" fill="red" />
<text x="100" y="50">Example SVG text 1</text>

Show hidden rect with text on hover of another poly

I need to use pure svg for a project. I know how to get this effect simply with divs but I dont know how to make it work with svg, I dont know what im doing wrong.
I want to show a hidden black rect with white text when you hover on another polygon (and the polygon is 0.1 of opacity normal and changes to 0.8 of opacity on the same hover) Something like a tooltip with opacity and with a nice smooth transition, but pure SVG.
.showme {
opacity: 0.3;
}
.showme:hover {
opacity: 0.8;
}
.desc {
visibility: hidden;
}
.showme:hover + .desc {
visibility: visible;
}

Please help :/
Thanks.
Keeping your svg, you can do with like this, but you'll need some slight changes:
<svg width="200" height="200" viewBox="0 0 1000 300"
xmlns="http://www.w3.org/2000/svg" version="1.1" >
<rect onmouseover='document.getElementById("desc").style.visibility = "visible"' onmouseout='document.getElementById("desc").style.visibility = "hidden"' x="1" y="1" width="998" height="298" fill="blue" class="showme"/>
</svg>
<svg width="200" height="200" viewBox="0 0 1000 300"
xmlns="http://www.w3.org/2000/svg" version="1.1" id="desc" >
<rect x="1" y="1" width="998" height="298" fill="black" />
<text x="250" y="150" font-family="Verdana" font-size="55" fill="white">Hello world!</text>
</svg>
