I couldn't find the way how to embed two SVGs into SVG document. I need to do it with ability of code which would manipulate with both child SVG-s, and would like to have independent coordinates on both of those areas.
I don't like to do it in HTML, because I consider it too limiting comparing to SVG.
Many thanks!
An SVG document fragment consists of any number of SVG elements contained within an ‘svg’ element.
Source: http://www.w3.org/TR/SVG/struct.html#NewDocument
Basically:
<svg …>
<svg id="a" …>…</svg>
<svg id="b" …>…</svg>
</svg>
<svg>
...
<image x="..." y="..." width="..." height="..." xlink:href="path/to/your/file.svg" ></image>
...
</svg>
One of solution is '[parent svg] - [g] - [child svg]' structure.
<svg>
<g transform="translate(-,-)">
<svg>
...
</svg>
</g>
</svg>
You can set the cordinate of child svg as transform(translate) of g element.

I am using Chartist.js for some charts and I need to target some elements inside the chart in order to generate some elements that are related to them. Is there a way to target such deeply nested child elements inside the "chart1". I need to target the "g" elements with the classes of "ct-series-a", "ct-series-b", etc... But since there are multiple charts on the page that ALSO have elements with these class names, I need to only target the ones that are contained in the chart with the id of "chart1".
HTML Mock-up
<div id="chart1" class="ct-chart">
<svg>
<g>
<g class="ct-series ct-series-a"></g>
<g class="ct-series ct-series-b"></g>
<g class="ct-series ct-series-c"></g>
</g>
</svg>
</div>
Somthing like this should help you.
const chart1 = document.getElementById("chart1");
const seriesA = chart1.getElementsByClassName("ct-series-a")[0]
console.log(seriesA.className)
// I did use className , for reducing console data to show u the result in console .
<div id="chart1" class="ct-chart">
<svg>
<g>
<g class="ct-series ct-series-a"></g>
<g class="ct-series ct-series-b"></g>
<g class="ct-series ct-series-c"></g>
</g>
</svg>
</div>
I have an <svg> element which contains some <image> elements under <defs> tag, which are referenced by some <use> elements, like this:
<svg xmlns="http://www.w3.org/2000/svg" ...>
<defs>
<image height="100%" id="test" width="100%" xlink:href="data:image/png;base64,..."/>
</defs>
<g transform="translate(111,222)">
<svg height="100" width="200" x="0" y="0">
<use xlink:href="#test"/>
</svg>
</g>
</svg>
I have a javascript function which iterates through the svg element, and at a certain point I get the image which is referenced by <use>.
What I want to do is to get the height/width of the <svg> above <use> from the <image> element.
If a try:
image.parentElement
I get the <defs> element, not the <use> element.
How can I find the element which referenced the image?
I can try to search the element which contains xlink:href="#test" , but is there a direct way to get this from the referenced <image> ?
Sorry for the noob question, but I'm new to javascript/html.
No. There is not a way to get the <use> element directly from the <image> element.
I would like to do "complex" animation with gsap and svgs.
but I don't know what is the best approach to this.
it is better to create and to import an unique svg with all the elements or maybe it is better 4 different svgs?
I have 4 different characters: a tree, a lamp, a desk and a man.
basically my animation is move the objects on the x, and appearing and to disappearing stuff.
If the elements of the animation are part of one complex animation, you can use one single SVG for this.
To control the DOM of the SVG via CSS and JavaScript you need to add the SVG directly inline into your HTML page. Not embed via img tag or object tag or similar.
<body>
<h1>My SVG Animation</h1>
<svg width="100" height="100" viewBox="0 0 300 100">
<circle class="animation-element-01" cx="50" cy="50" r="40"/>
<rect class="animation-element-01" x="150" y="20" width="150" height="150"/>
<!-- etc -->
</svg>
</body>
Another advantage of this method is, that there is no additional html requests.
Plus the whole animation can be made responsive via the viewBox.
I have an svg rect like this:
<svg class="legend-square">
<defs>
<pattern id="pattern1" width="3"
height="3" patternunits="userSpaceOnUse" patterntransform="rotate(-45)">
<rect width="2" height="3" transform="translate(0,0)" fill="purple"></rect>
</pattern>
</defs>
<rect width="12" height="12" fill="url(#pattern1)"></rect>
</svg>
When I inspect the second rect with Chrome it has no width and height. There are no CSS rules applying to it. Why doesn't it get affected by width and height?
One of the reasons why SVG file is rendered on front-end with zero height and width is missing <svg> tag attributes "height" and "width".
Incorrect:
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 49 30">
Correct:
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 49 30" width="49" height="30">
It works fine.
If the snippet works individually but size of div containing it in you code appears 0x0 then look into : Why is my div's height zero
Its usually caused when float is set.
<div>
<svg class="legend-square">
<defs>
<pattern id="pattern1" width="3" height="3" patternunits="userSpaceOnUse" patterntransform="rotate(-45)">
<rect width="2" height="3" transform="translate(0,0)" fill="purple"></rect>
</pattern>
</defs>
<rect width="12" height="12" fill="url(#pattern1)"></rect>
</svg>
</div>
You really haven't provided enough information. For instance, what is the parent element of your SVG?
Just because your <rect> has a width and hight, it doesn't mean your SVG does. SVG is not like HTML, where elements expand to fit their children. SVG is like the <canvas> element. You have to make sure it either explicitly (or implicitly) has a size.
You have not specified width or height attributes for your <svg> element, so they are both defaulting to "100%". What they are 100% of depends on what size the SVG's parent element is. Hence my first question above.
For an 'inline' SVG element you have to apply the styles, inside the svg element itself.
inside the <defs></defs> tags. Since it has its Own DOM[Document Object Model], Css Apllied to it from Outside, will have no effect.
You have Several different options for embeding an SVG, You can use it inline as in your example where you declare the <svg></svg> inside of your html/php document or you can use one of the many other methods listed below;
embed an: ..............................................<img src="../pathtoyourSvg"></img>
embed as an img with a fallback option: <img src="logo.png" srcset="logo.svg" alt="My logo">
use an: ....................................................<object type="image/svg+xml" data="image.svg">
<!-- Your fall back here -->
<img src="image.svg" />
</object>
use: .........................................................<embed type="image/svg+xml" src="image.svg" />
use an: ....................................................<iframe></iframe>
embed the Svg inside of a canvas element using Javascript:
var img = new Image();
img.onload = function() {
ctx.drawImage(img, 0, 0);
}
img.src = "path2your.svg";
You may Also Embed the Svg using Css Background image,
ie:
.mySvgContainer{
background-image:url('PathToMySvg');
}
But from the comments & Questions I have read, this need to be either Url or Base64 encoded, which seems a bit Hacky and not very convenient.
each of them have their own advantages and disadvantages.
Because of security reasons, some SVG embedding methods will block access to external resources including CSS, fonts and javascript. Especially when we have multiple images, ideally our embedding method should be able to refer to a single CSS, font or javascript file (to save resources) and be able to manipulate our embedded SVG.
Also worth mentioning that if you have display:flex; attached to an elemnet or its parent then the width and height values will have no effect on the flex items. So It may appear as 0, 0, in the console.
Some Useful Information & related questions:
Svg Coords & Units w3.org
Svg Width - Height
Applying Styles to an embedded Svg
You can wrap your svg element inside the html5 object element.
<style type="text/css">
object{
width:300px;
height:200px;
}
object svg{
width:100%;
height:100%;
}
</style>
<object>
<svg class="legend-square">
<defs>
<pattern id="pattern1" width="3"
height="3" patternunits="userSpaceOnUse" patterntransform="rotate(-45)">
<rect width="2" height="3" transform="translate(0,0)" fill="purple"></rect>
</pattern>
</defs>
<rect width="12" height="12" fill="url(#pattern1)"></rect>
</svg>
</object>
You can set height and width on the object element just link any other html element while you can set height width to 100% for SVG element. It will work. But first, test your SVG by opening the file directly in chrome.
The idea is pretty simple:
I have an SVG path and an Rect,
I need to make the path carve through the Rect, the resulting "hole" should be see-through.

Here's an image of what it would probably look like if we can carve that hole:
http://i.stack.imgur.com/5fjBR.png
The Path is dynamically generated and can be quite complex, so I can't really eyeball the result.
It has to be done in javascript (or with some very clever usage of styles).
I need the result to be a DOM node that I can eventually move between z-indexes (could be grouped? a resulting "difference" path calculated in js?).
Performance and experimental features are not an issue, this is aimed at nwjs app.
Some other notes:
I'm already using jQuery, svg.js and a bunch of other libraries, so adding
new libraries is not a problem.
The rect could also be replaced by just a color filled div, if that helps solve the problem.
Ive already tried masks and clips but couldnt come to a working solution.
Any help appreciated, Thank you in advance.
A mask is what you need. I'm not sure what you tried before, but it should do what you want.
Just create a mask like so:
<defs>
<mask id="theMask">
<rect width="100%" height="100%" fill="white"/>
<path id="thePath" d="..." fill="#000000"></path>
</mask>
</defs>
Either move the original path into the mask, or copy it and hide the original.
Then apply the mask to the rect
#theRect {
mask: url(#theMask);
}
