Is it possible to have multiple SVGs that are next to each other horizontally. I know that when you append a SVG in D3, it appends in below the previous SVG. But now I have the previous SVG on half the page, and I want to translate this SVG from below the previous SVG to the right of the previous SVG. I tried using the transform-->translate attribute on the second svg but it did not work:
var secondSVG= d3.select("#div1").append("svg").attr("width",960).attr("transform"),"translate(500, -500)");
In Chrome 24, IE10, and FF17 this jsFiddle worked as expected. The key seemed to be setting the width and height stylesheet properties.
HTML:
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" height="190" id="svg1">
<polygon points="100,10 40,180 190,60 10,60 160,180"
style="fill:lime;stroke:purple;stroke-width:5;fill-rule:evenodd;">
</svg>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" height="190" id="svg2">
<polygon points="100,10 40,180 190,60 10,60 160,180"
style="fill:lime;stroke:purple;stroke-width:5;fill-rule:evenodd;">
</svg>
CSS:
svg
{
width: 190px;
height: 190px;
}
Awhile back I wanted to do something similar, but I eventually settled on using a single svg element with two internal g elements, one of them transformed to the right. You can see the eventual finished product here.
General idea: Wrap each SVG in a div element that is displayed as inline-block.
This works with the following approach that I personally like anyway.
Set the width and height attributes of the SVGs to 100%.
"Inner impact": Specify the size of the drawing area (which the units of the elements in the SVGs, like circle, relate to) with the viewBox attribute; this typically goes together with the preserveAspectRatio attribute.
https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/viewBox
https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/preserveAspectRatio
"Outer impact": The SVGs will adapt to the size of their container. Style it (width and/or height) according to your wishes. Of course you need enough horizontal space.
Minimal example:
<div style="display: inline-block; width: 42%">
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" viewBox="-80 -45 160 90" preserveAspectRatio="xMinYMin meet">
<circle cx="0" cy="0" r="39">
</svg>
</div>
<!-- Just a copy from above. Right of (not below) the previous SVG. -->
<div style="display: inline-block; width: 42%">
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" viewBox="-80 -45 160 90" preserveAspectRatio="xMinYMin meet">
<circle cx="0" cy="0" r="39">
</svg>
</div>

I have been trying to implement the following requirements.
1. SVG path to have multiple colors on different sections (eg - red color the curves and rest of it, in black color)
2. Only allow mouse event- click on those colored areas (curves)
I have tried with plain javascript and snap.svg

[Codepen using SNAP.svg][2]
[1]: https://codepen.io/sanathko1234/pen/vvMQQZ
[2]: https://codepen.io/sanathko1234/pen/OrGoRa
How can this be achieved?
One solution would be to use the path twice: first the green one and next the one using stroke-dasharray. The dashes are only over the curves. If you don't like the position or the length of the dashes change them to what you need. The gaps are not sensitive to mouse events, only the dashes are.
In css I've added #gold:hover{cursor:pointer} so that you can see that only the dashes are sensitive to the mouse.
I hope it helps.
svg{border:1px solid}
use{fill:none;stroke-width:18;}
#gold:hover{cursor:pointer}
<svg viewBox="-10 50 580 360" width="580" height="360" xmlns="http://www.w3.org/2000/svg">
<defs>
<path id="svg_1" d="m555,272c1,0.76736 4,85.76736 -71,97.76736c-75,12 -387,-39 -388,-39.76736c0,-0.23264 -29,-1.23264 -45,-21.23264l-42,-124.76736c-3,-11.23264 -3,-21.23264 3,-26.23264c6,-5 46,-67 69,-69.76736l474,184z" />
</defs>
<g>
<title>background</title>
<rect fill="#fff" id="canvas_background" height="360" width="580" x="-10" y="50"/>
</g>
<g>
<title>Layer 1</title>
<use xlink:href="#svg_1" stroke="green" />
<use xlink:href="#svg_1" stroke="gold" stroke-dasharray ="130 370 110 60 90 40 90 400 52.45" id="gold" pointer-events="stroke" />
</g>
</svg>
Observation: the sum of the dashes and the gaps is 1342.45 which is also the total path length.
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.
I'm making a web interactive test for musicians, and got stuck up on, well, interactiveness.
Users are supposed to move notes on a stave and adjust them.
SVG pathes are rendered as notes, with a separate parent div container for each note. Parent div is dragged on to the stave, and then can be resized ( I'm using jQuery UI for this, with option "handles" set to "e", so div can be resized only to the right). After this point I can not figure out how to correctly resize the SVG note inside it, because what needed to be resized, is not the whole SVG, but just one part.
SVGs look like this:
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="24" height="32" viewBox="0 0 24 32" class="svgnote" preserveAspectRatio="none">

Picture example
I added a picture, where above red figure
it's an initial state of a note;
upper red arrow is pointing out on a line, which is the only part of svg that needs to stretch out to the right.
lower red arrows aside -- the note should (somehow?) be rotated up and down, to make 3rd state possible
is what final state of note I'm looking for.
What I have done:
except excessive googling, not much. I tried to set "width" of SVG image to "100%" of the parent div, and add preserveAspectRatio="none", but all I got is ugly stretched note.
As for rotation I do not have even a single idea from what should I start.
I'd be eternally grateful if someone point out for what should I google, or maybe a library should I use. I'm sensing a solution to this is close somewhere, I'm just missing it because of my very limited experience in the field.
Thank you all.
Here's a 10mins hack. Connecting bar needs more work but the gist is use a collection of <symbol>for your musical notation and a better path (eg: polygon?) for the connecting bar.

I'm trying to view a polygon with dynamic coordinates (retrieved from the server) inside a svg space.
What i want to happen is that this polygon will be stretched over the entire svg, instead what i was able to achieve is either viewing a very small polygon or not viewing it at all.
Here is my best attempt so far:
<svg width="100%" viewBox="4980 4980 5020 5020">
<polygon points="5020,5000 5010,5017.320508075689 4990,5017.320508075689 4980,5000 4990,4982.679491924311 5010,4982.679491924311"></polygon>
</svg>
The last two parameters of viewBox are width and height.
<svg width="100%" height="100%" viewBox="4980 4980 40 40">
<polygon points="5020,5000 5010,5017.320508075689 4990,5017.320508075689 4980,5000 4990,4982.679491924311 5010,4982.679491924311"></polygon>
</svg>
Is it possible to load two SVGs with JavaScript? For example, then use the first SVG as the base and the second SVG as a badge in the corner and then scale the combination as one and save as a single SVG?
Yes, you can append an <svg> element into an svgDocument :
var svgDocs = document.querySelectorAll('svg');
svgDocs[0].appendChild(svgDocs[1]);
svgDocs[1].width.baseVal.value/=3;
svgDocs[1].height.baseVal.value/=3;
svg{ border:1px solid}
<svg version ="1.1" id="first" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 250 250" height="250" width="250">
<circle cx="60" cy="60" r="50" fill="pink"/>
</svg>
<svg version ="1.1" id="second" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 250 250" height="250" width="250">

</svg>

0: Load your resources with:

1: Use transforms to scale, translate, as needed:
https://developer.mozilla.org/en/docs/Web/SVG/Attribute/transform
2: To convert the final composite SVG element to file use/modify https://github.com/NYTimes/svg-crowbar, which I found from this Convert JavaScript-generated SVG to a file
or better discussion:
Generating, viewing, and saving SVG client-side in browser
disclaimer: I haven't tested this approach, so can't guarantee it, but I've done a lot of work programmatically with SVGs in the last few months, and I think it will work.
