So I'm trying to make a simple textpath .svg that would be a vertical line with some text. The problem I am getting is that the <defs> tags seem to throw everything off. I think it has something to do with my xlink:href but I can't seem to pin down what exactly.
<svg version="1.1"
baseProfile="full"
width="20" height="600"
xmlns="http://www.w3.org/2000/svg">
<defs>
<path id="testPath" d="M 10 10 L 10 600 z"
stroke="black" stroke-width="3" />
</defs>
<text>
<textpath xlink:href="#testPath">
teeeest
</textpath>
</text>
</svg>
Any help would be appreciated.
Your sample will work fine inlined in a browser, because the browser knows about the xlink namespace.
If your SVG is an external file, then more strict XML parsing is performed and all namespaces used have to be defined.
All you need to do is add a definition for the xlink namespace to your outermost <svg> element.
<svg version="1.1"
baseProfile="full"
width="20" height="600"
xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink">
SVG is a case sensitive language so textpath actually needs to be written as textPath.
If you embed the SVG in html then you don't need namespaces as html doesn't support them (unlike xhtml). If you have your SVG standalone you'll also need xmlns:xlink="http://www.w3.org/1999/xlink" on the root <svg> element.

Im using object and use in order to have a single file for all my svg icons. But what Im seeing is that icons.svg file gets redownloaded every time a new icon is used in application. It's not strictly for every icon but it seems to happen very often. I couldn't diagnose it in my searches.
Is this normal behavior? Should it keep downloading the file? Am I just supposed to cache it?
How I include svg file to index.html:
<object type="image/svg+xml" data="/static/icons.svg" style="display: none;"></object>
How I use icons in various places:
<use href="/static/icons.svg#foo"></use>
<use href="/static/icons.svg#bar"></use>
Example icons.svg:
<svg xmlns="http://www.w3.org/2000/svg">
<symbol id="foo" viewBox="0 0 100 100">
<circle cx="69.37" cy="37.27" r="16.97"/>
</symbol>
<symbol id="bar" viewBox="0 0 100 100">
<circle cx="69.37" cy="37.27" r="16.97"/>
</symbol>
</svg>
I am working on a project that generates super strong passwords (for practise).
When using inline SVG, I was just wondering if there are any unnecessary attributes to the SVG code, because I'm trying to make it as short as possible.
In this specific snippet, I have a copy-to-clipboard icon.
Here is the code:

Let's start with what is generally superfluous:
version="1.1" is not interpreted by any browser or renderer I know of.
style="enable-background:new 0 0 488.3 488.3;" While setting a style attribute in general might be good idea, the property enable-background is deprecated and was never implemented anywhere
The following might or might not have their place, depending on circumstances:
<?xml version="1.0" encoding="iso-8859-1"?> must be the first line of a XML-conforming standalone SVG. Note the encoding is not the default utf-8. If the SVG is used inline in HTML, browsers just ignore the line (if it is not the first line of the document), but strictly speaking its use in any other place breaks XML-wellformedness.
xmlns:xlink="http://www.w3.org/1999/xlink" Defining a namespace is only needed if you really have an element/attribute somewhere that uses it, for example a <use xlink:href="..." />. Even then, most browsers nowadays support the namespace-less href.
xml:space="preserve" is only usefull if you have <text> elements with <tspan> children. It will then govern whether whitespace between those child tags is interpreted as a space character.
x="0px" y="0px" On an outermost <svg> element in a standalone file, x and y are always ignored. If the SVG is embedded inline in other content, values other than the default 0 might have an effect, depending on the host language. (In HTML, you'll probably have to use CSS top and left instead.)
And finally, what is missing:
width and height have a default of 150px and 100px when the SVG is used inline. (For standalone files, the viewBox values will be used when they are missing.)
preserveAspectRatio has a default of xMidYMid meet. It defines how the viewBox is fitted into the SVGs dimensions if the aspect ratio of width, height and viewBox do not match.
I'm using librsvg 2.39.0 to render the following SVG file to PNG. Inkscape and Firefox render it without any issues:
<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg" width="400" height="200" viewBox="0 0 20 10" version="1.1">
<rect width="100%" height="100%" fill="#ffffff" />
<text style="font-family: Helvetica;" stroke="none" x="7" y="5" font-size="1.6" fill="black">
This is some text
</text>
</svg>
However, it looks like, with librsvg, the text characters get aligned to the user coordinate grid, and the kerning is completely broken:
The issue can be replicated in the console by installing the librsvg2-tools package and running rsvg-convert < input.svg > output.png.
Is there something wrong with the file? The W3C validator shows it as valid. How do I teach librsvg to accept a fractional font-size in user coordinates?
This works fine now with rsvg-convert 2.40.20
I've been having problems with symbols in SVG files. They are currently not displaying in browsers.
For example I created this basic SVG file in inkscape to show the problem:
<svg xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns="http://www.w3.org/2000/svg" height="100" width="100" version="1.1" xmlns:cc="http://creativecommons.org/ns#" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 100 100" xmlns:dc="http://purl.org/dc/elements/1.1/">
<defs>
<symbol id="circle">
<circle style="color-rendering:auto;color:#000000;isolation:auto;mix-blend-mode:normal;shape-rendering:auto;solid-color:#000000;image-rendering:auto" stroke-width="3.257" stroke="#008000" cy="1000.1" cx="34.598" r="12.879"/>
</symbol>
</defs>
<g transform="translate(0 -952.36)">
<use xlink:href="#circle"/>
</g>
</svg>
And it should look like this:
But for some reason its not displaying as such in chrome, does anyone know why?
You're drawing the initial symbol mostly outside the viewbox - your viewBox is 100 x 100, but your cy is 100.1. This seems to disable drawing completely, so when you bring it back into the viewbox with the translate, there's nothing there. Adjust your cy so you're drawing inside the viewbox and reduce your translate to compensate.
Inside my website, I am embeding a few svgs. They all seem to work just fine in Chrome, Firefox, IE(9+) and in Safari. Howvere as soon as there is image included in the svg, safari does not render the image.
Based on the previous similar topic I have tried the following:
SVG <image> elements not displaying in Safari - enclosing
<use>
tag like this <use></use>
SVG Image dosen't appear in Safari - I dont find this very usefull,cause this is deleting aprt of the svg.
Not able to render SVG image in Safari - Added
<meta http-equiv="Content-Type" content="application/xhtml+xml"> in header.
And beyond that, I dont really know what else to try. Maybe one more interesting thing to note is that inside my page, image is not displayed, but I can open svg file in safari(just the file) and it will be renderd correctly. Further more, after it's opened in the browser as a file, it renders inside the page as well. And I embed the svg to the page with img tag.
<img src="mysvg.svg" class="center-block"/>
This is my svg:

I have reduced base64 image string, to shorten the code. Full svg can be found here.
UPDATE: Just to be clear, svg shows in the browser(safari) but image is missing (I can see just border).
It looks like this WebKit bug is responsible for the problem: https://bugs.webkit.org/show_bug.cgi?id=99677
The workaround we use in our application is to have a script which finds all img elements displaying SVG images and add hidden object elements loading the same SVGs (<object style="position: fixed; width: 0; height: 0;" data="image.svg" type="image/svg+xml"></object>).
The reason it works is that the object tag properly loads the embedded images into the image cache, so that they are visible within the SVGs loaded using the img tags.
The advantage of this approach is that the images are still displayed using the img tag, so that the workaround can be applied (and later removed cleanly when the browsers are eventually patched) without affecting the rest of the application/website.
The disadvantage is the creation of an extra object tag for each SVG image.
This solution works for me when displaying an embedded SVG image in Safari.
replace
<img src="image.svg">
with
<object data="image.svg" type="image/svg+xml"></object>
I ran into this problem where I was using Ajax to load the svg spritesheet onto the page. If I had a on the page before the spritesheet was loaded, it would fail and would not resolve once the spritesheet was avaialble. Any added to the dom after the spritesheet was loaded were fine. I had to delay putting the items in the dom until after the spritesheet finished loading.
This only affected IOS. All other browsers didn't care about the order.
It seems that answer from this question works: What could make Safari skip clip-path AND mask with SVG?. See instructions in link from answer.
You have to recreate your clip path to make it visible. And </clippath> tag is not pushed after </image> tag.
Here is the little changed code (link to my image inserted so you will have to change it):
<?xml version="1.0" encoding="utf-8"?>

So Anto Jurković pointed out, there are some known issues with Safari and clipPath. What Safari likes is if you dont define polygon but put it straight in to clippPath. Also you must then group clipPath separately.
But I still could not get svg to render the image if I used img tag for svg - <img src="svg"/>. So at the end I have embeded it like this:
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
width="328px" height="328px" viewBox="0 0 328 328" enable-background="new 0 0 328 328" xml:space="preserve">
<g>
<clipPath id="SVGID_2_">
<polygon id="SVGID_1_" points="1.414,164.001 164,326.586 326.586,164.001 164,1.414 "/>
</clipPath>
</g>
<image clip-path="url(#SVGID_2_)" overflow="visible" width="338" height="532" id="DSC_x5F_0112-2" xlink:href="data:image/jpeg;base64,/9j/.....r/fdeaS//9k=">
</image>
<g>
<path fill="#FFFFFF" d="M164,328.001L0,164.002L164,0.001l164,164.001L164,328.001z M1.414,164.002L164,326.587l162.586-162.585
L164,1.415L1.414,164.002z"/>
</g>
</svg>
I can confirm that this renders correctly in mobile safari(on ipad and iphone, windows safari and mac safari - latest versions).
So to sum it up...I have this svgs in separate html file and render them when needed.
