svg animation not animating smoothly - javascript

Here I give code of html which not work properly, how can I get it to move smoothly?
I am happy to use jQuery if necessary.

An animation with easing between two path definitions can only work if they match structurally.
They must have the same number of control points and all path commands must be identical.
You cannot exchange absolute (C) commands for relative (c), or shorthand curve commands (S) for full (C).
Optional command letters (for repetitions of the same command) can be used or left out.
Whitespace can have different length or be exchanged for commas.
The reason for that is actually not that hard to understand: To compute an interim state, the renderer needs to formulate a path definition by choosing an appropriate value between the "from" and "to", for every control point. There can be no computed interim if the letters or the number of points differ.
Currently you go from
M1361.7-0.1L124.1,0.1L4,161.7c0,0-27.6,61.2,61,57.2s1297-110.5,1297-110.5L1361.7-0.1 z
to a much longer command
M1361.7-0.1 L124.1,0.1 L4,161.7 c0,0-9.6,21.3,0.7,37.9 c9.5,15.4,31.4,19.7,60.3,19.3 c70.7-1,109.2-28.3,161-41.9 c87.3-22.9,103,21.9,238,14c64.4-3.8,55.7-13.6,143-25 c129.3-16.8,154.8,4,273-7 c118.6-11,125.3-35,230-45 c107.5-10.2,196.2,5.9,252,20 C1361.9,89.3,1361.8,44.6,1361.7-0.1z
That is much too different.
And there is a fair amount of work involved to get them to match. I don't know if Illustrator will be helpfull in that regard. It changes commands for what it deems optimal and if that happens in one command variant and not the other, easing will still not work. The only thing you can rely on is writing down the path commands in a text editor one below the other and comparing number for number, letter for letter.
The version below was worked out with Inkscape, some experience, and a lot of trial and error.

SVG icons in ReactJS

I have to move an SVG icon from a regular website to a ReactJS website. The SVG has to be modified a little to make it compatible with JSX, so I've removed all the ':'s and replaced them with camel case attribute names for JSX compatibility. The only issue is the d attribute.
The SVG now looks like:
<svg id="Logo" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlnsXlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="100px" height="100px" viewBox="0 0 900 800" enable-background="new 0 0 1024 1024" xmlSpace="preserve">

This gives me the following error:
Module build failed: SyntaxError: Unexpected token (90:58)
This makes sense, but in the d attributes in my case there are parts like M596.473,389.394c0. As you can imagine, the letter c between the 4 and 0 cause issues as the letter is not an integer.
How can I make this SVG work without using a library or something else? I just want to convert this SVG to valid JSX.
Change style={{fill="#B8CD43"}} to style={{fill: "#B8CD43"}} every place, it will work.
There is no need of dangerouslySetInnerHTML. Here is the working Demo
React does not play nice with SVG yet. If your svg is static I personally find it much easier to do it this way:
var img = `<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"
viewBox="0 0 252.5 148.7" xml:space="preserve">
<g>
<polygon points="252.5,0 252.5,52.6"/>
</g>
</svg>`
In string you can put your svg exactly how you read it from file/DB without any extra conversions.
And then later use it in render like this:
<div dangerouslySetInnerHTML={{__html: img}}/>

canvg fails on svg with xmlns

I am using canvg to render the following svg to the canvas however it fails. I am not sure why
<svg class="circularReferenceSVG" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<marker xmlns="http://www.w3.org/2000/svg" id="triangle" viewBox="0 0 10 10" refX="0" refY="5" markerUnits="strokeWidth" markerWidth="4" markerHeight="4" orient="auto">
<path d="M 0 0 L 10 5 L 0 10 z" fill="#000000"></path>
</marker>
</svg>
My guess is that it has to do something with xmlns. I could not find on the canvg webpage anything about it. Any help will be appreciated.
Here is the screenshot of where the canvg seems to fail
Here point and angle is undefined
you need to wrap marker tag with defs tag.

Masking an image with an existing SVG path

I have a set of SVG paths which make up a logo.
Then, I want to have several images (to appear as the SVG) which slide through gradually. My problem is that I cannot make them work as the background, in other words, I want the SVG to mask the image(s).
I have a SVG like this:
<svg class="polygon" 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="225.533px" height="261.262px" viewBox="0 0 225.533 261.262" style="enable-background:new 0 0 225.533 261.262;" xml:space="preserve">
<g id="svg-draw">
<path data-name="nav-projects" data-href="<?php print JUri::base() ?>projects" data-ajax="true" class=" st4 hover-logo" d="M26.05,147.366c-4.384,10.375-21.823,47.717-24.713,71.831c-2.804,23.373,2.034,40.255,27.625,37.926c6.952-0.97,15.662-4.346,24.417-9.214"></path>
</g>
<image clip-path="url(#svg-draw)" height="100%" width="100%" xlink:href="<?php print THEME_URL."/img/rev1.jpg"; ?>" />
</svg>
And if you notice, I have put the image tag right inside the SVG. But nothing happens. I also have removed most of the Paths of the svg in the above example, because they are too long to be copied here.
I used the clip-path property of the image, but to no avail.
You can't just clip with any element. You have to define a <clipPath> and clip with that.
<svg class="polygon" version="1.1" id="Layer_1"
xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
width="225.533px" height="261.262px"
viewBox="0 0 225.533 261.262">
<defs>
<clipPath id="svg-draw">
<path d="M26.05,147.366c-4.384,10.375-21.823,47.717-24.713,71.831
c-2.804,23.373,2.034,40.255,27.625,37.926
c6.952-0.97,15.662-4.346,24.417-9.214"></path>
</clipPath>
</defs>
<image clip-path="url(#svg-draw)" height="100%" width="100%"
xlink:href="http://placekitten.com/200/300" />
</svg>

JavaScript - Is there a way how to draw SVG path UNDER the content?

I need a path that goes UNDER the content (text) - is there a way how to do that?
(as already been answered somewhere else, z-index doesnt affect svg paths)
You can declare PATH and TEXT in different SVG layers, and put one layer onto another like this
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" style="position:absolute;z-index:1">
<text x="100" y="15" fill="red">I love SVG</text>
</svg>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" style="position:absolute;z-index:0">
<path d="M150 0 L75 200 L225 200 Z" />
</svg>

How can I animate a drawing effect? (Preferably css3 only)

I want to make a drawing effect of tree that looks something like this one with a progressive line like here. I would prefer using only css3 with svg/canvas and js. Do you have any ideas?
More info:
I tried to cut a tree into pieces and animate piece by piece the appearance but it's not cursive cause it's to much details on syncronizing delays and durations because every piece has a different length and so on. All of this is made without svg. I want to now if i can animate a line path.
Yes, take a look at this rendering of the Bahamas Logo using CSS 3
It describes his process, and techniques. Also you can view the source.
There are more that can be found here
Update:
Also maybe this Sencha Animator product may help?
You can do this with plain SVG. SVG provides the <animate> element for declarative animation.
What you want (as I understand it) is a line that appears as if it was drawn in front of the viewer's eyes. You can use the stroke-dasharray property for this purpose. This property defines a dash pattern using a series of values that defines the length of dashes and gaps. The strategy would be: First we have a dash that has length 0 and a gap that is at least as long as the whole path. This means we see nothing (or only the first point at the start of the path). In the end we want a dash that's at least the full length of the path. We want the dash to gradually become longer and longer until it reaches its final length (the length of the full path).
The simplest case would be:
<svg xmlns="http://www.w3.org/2000/svg" width="400px" height="300px">
<!-- This is the path of a spiral -->
<path d="m 7.1428565,220.9336 c 0,0 13.6660115,54.75386 218.5714335,51.42857 C 430.61971,269.03688 478.47682,99.194335 206.69537,110.78149 -65.086093,122.36866 45.497658,213.22607 210.28635,207.29759 375.07503,201.3691 429.75297,97.468925 207.14285,82.362175 -15.467268,67.255425 64.868608,160.66909 210,153.79075 c 145.13139,-6.87834 137.69998,-93.087405 11.42857,-99.999995 -126.271412,-6.9126 -150.382292,28.03248 -24.28571,35.71428 126.09659,7.6818 72.6601,-44.83727 -5.71429,-84.2857095"

More sophisticated things can be done using multiple values (using the values attribute) instead of one from and one to value:
<svg xmlns="http://www.w3.org/2000/svg" width="400px" height="300px">
<path d="m 7.1428565,220.9336 c 0,0 13.6660115,54.75386 218.5714335,51.42857 C 430.61971,269.03688 478.47682,99.194335 206.69537,110.78149 -65.086093,122.36866 45.497658,213.22607 210.28635,207.29759 375.07503,201.3691 429.75297,97.468925 207.14285,82.362175 -15.467268,67.255425 64.868608,160.66909 210,153.79075 c 145.13139,-6.87834 137.69998,-93.087405 11.42857,-99.999995 -126.271412,-6.9126 -150.382292,28.03248 -24.28571,35.71428 126.09659,7.6818 72.6601,-44.83727 -5.71429,-84.2857095"
stroke-width="10" stroke-linecap="round" fill="none" stroke="black" stroke-dasharray="0,2305">
<animate attributeName="stroke-dasharray" dur="5s" repeatCount="indefinite"
values="0,2305;
2000,305;
2305,0"/>
</path>
</svg>
You can specify the precise timing (when which value listed in values will be reached) using the keyTimes attribute:
<svg xmlns="http://www.w3.org/2000/svg" width="400px" height="300px">
<path d="m 7.1428565,220.9336 c 0,0 13.6660115,54.75386 218.5714335,51.42857 C 430.61971,269.03688 478.47682,99.194335 206.69537,110.78149 -65.086093,122.36866 45.497658,213.22607 210.28635,207.29759 375.07503,201.3691 429.75297,97.468925 207.14285,82.362175 -15.467268,67.255425 64.868608,160.66909 210,153.79075 c 145.13139,-6.87834 137.69998,-93.087405 11.42857,-99.999995 -126.271412,-6.9126 -150.382292,28.03248 -24.28571,35.71428 126.09659,7.6818 72.6601,-44.83727 -5.71429,-84.2857095"

See this in action on Tinkerbin.
Something similar can be done using CSS3:
<svg xmlns="http://www.w3.org/2000/svg" width="400px" height="300px">
<style type="text/css">

}
#keyframes animateDash {

}
</style>
<path d="m 7.1428565,220.9336 c 0,0 13.6660115,54.75386 218.5714335,51.42857 C 430.61971,269.03688 478.47682,99.194335 206.69537,110.78149 -65.086093,122.36866 45.497658,213.22607 210.28635,207.29759 375.07503,201.3691 429.75297,97.468925 207.14285,82.362175 -15.467268,67.255425 64.868608,160.66909 210,153.79075 c 145.13139,-6.87834 137.69998,-93.087405 11.42857,-99.999995 -126.271412,-6.9126 -150.382292,28.03248 -24.28571,35.71428 126.09659,7.6818 72.6601,-44.83727 -5.71429,-84.2857095"
stroke-width="10" stroke-linecap="round" fill="none" stroke="black" stroke-dasharray="0,2305"/>
</svg>
Decide for yourself which method you prefer.
