Hello I came across a really interesting looking website :
http://digitalbakery.org/
I wonder how did they provide a background image for the animated SVG Path elements?
I have tried to set a background image for SVG before. Did not work. However looking in the DOM I see in fact the images and SVG are entirely separated. The img are in a ul element specified somewhere.
Is the Path element, when hover, has its opacity reduced to zero hence revealing the img underneath? If so I cannot seem to figure out how is the exact location worked out. How can this effect be achieved?
I have used the named clipPath to crop images. The simplest example:
<svg id="pLayout">
<g>
<clipPath id="hex-mask">
<path d="..."></path>
</clipPath>
</g>
<image x="..." y="..." xlink:href="..." **clip-path="url(#hex-mask)"** />
</svg>
Location calculates by container's vertexes.

Is there any place where I can upload an icon and get an SVG string vector?
Also, what are those tags in the code below?<g> <path> and viewBox, data-original, xmlns, d tags are?
Lately, Is the performance worth using SVG in place of regular icons?
<svg viewBox="0 0 512 512">
<g xmlns="http://www.w3.org/2000/svg" fill="currentColor">
<path d="M0 0h128v128H0zm0 0M192 0h128v128H192zm0 0M384 0h128v128H384zm0 0M0 192h128v128H0zm0 0"
data-original="#bfc9d1"
/>
</g>
</svg>
Here's a very good guide to using SVG with react. https://www.sanity.io/guides/import-svg-files-in-react
There are many online convertors you can use to create svg's
e.g https://www.pngtosvg.com/
The SVG <g> element is used to group SVG shapes together.
The SVG <path> element indicates that the vector to draw is a path. The could alternatively be a polyline or a shape e.g circle.
The <viewBox> attribute is a list of four values: min-x, min-y, width and height
The xmlns attribute is XML Namespace which is needed to use the correct DTD - Doctype Declaration
The <d> attribute defines the path that will be drawn.
From my experience SVG performs significantly faster when using inline SVG's.
The main blocking element for page loading is the numberous amount of files that load sequentially. Using inline svg loads all the images within the page file.
The major benefit of SVG's are the scalability of vector over raster when zooming or viewing at differant resolutions.
I created a radial with two tiers of options. I did in a way that isn't really dynamic and isn't really responsive to screen size. I now need it to be both of those things. Here is what it looks like when on the screen size I designed it for.
I created a working demo on sandbox that has the dimensions set how I need to use it on. This is what it looks like.
Here is link WORKING DEMO
any help is appreciated. Also keep in mind the outer tiers can have less or more options. it would be great if the blue toggle button would always align at the bottom of the radial like under the En of Energy Loss
I would consider using an SVG ViewBox in order to maintain consistency. What this basically does is create a consistent scalable SVG, mapping the size and coordinates of its container into a consistent range inside the SVG.
For example:
<div height="400px" width="400px">
<svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg">
<rect x="0" y="0" width="100%" height="100%" stroke="red" fill-opacity="0"/>
<circle r="4" cx="10" cy="10"/>
</svg>
</div>
So it basicalley creates a mapping from the 400x400 dimensions of the div, into the 100x100 of the svg, so the circle positioned at (10, 10) inside the svg will actually be in coordinates (40, 40) of the div
I am attempting to make a world map made from an svg comprising many circles. I based this from a codepen I found here: https://codepen.io/mvaneijgen/pen/NRzENO
E.g.
<svg viewBox="0 0 845.2 458">
<circle class="st0" cx="826.1" cy="110.3" r="1.9"/>
<circle class="st0" cx="819.3" cy="110.3" r="1.9"/>
<circle class="st0" cx="819.3" cy="117.1" r="1.9"/>
<circle class="st0" cx="812.6" cy="90" r="1.9"/>
The map is great. I have been dividing it up into coloured continent regions using classes. These change colour when hovered over. All good so far. Most of my functionality is there.
The issue is that you have to be hovering directly on a circle to make the colour change happen. I am using a javascript mouseover event to change the colour.
Is there any way of increasing the area of effect around the circle elements? Maybe putting an invisible square either behind or in front? I am still getting to grips with front-end stuff and any pointers here would be great.
That’s the right idea: transparent rects behind each circle. (Or transparent continent-shaped paths based on geo data, depending on what you’re going for.)
The trick is to use the SVG CSS property pointer-events. Setting it to fill or all should do the trick.
I'm using a circular clip path for my nodes (in d3.js) as follows:
<g class="node" id="140" transform="translate(392.3261241288836,64.3699106556645)">
<image class="mainImage" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="images/manual-story-140.jpg" width="100" height="116.66705555685185" x="-50" y="-50" clip-path="url(#140)">
</image>
<clipPath class="clipPath" id="140">
<circle class="clipPathCircle" stroke-width="1" r="42"></circle>
</clipPath>
<circle class="outlinecircle" stroke="#0099FF" fill="url(#myLinearGradient1)" stroke-width="3" r="42"></circle>
</g>
But in Firefox the images don't load because the circle element within the clipPath element doesn't inherit the position of the node (i.e. from the g element).
In Chrome/Safari, everything works great and when I open up the console and hover over the circle element that's within the clipPath element it clearly shows the circle in the correct place (with dimensions of 84x84 since the radius is 42).
But in Firefox I see no images, and when I hover over the circle using the console I see it's positioned at the top left of the screen with dimensions 0x0.
Any ideas what I'm doing wrong here? Do I have to give an absolute position of the circle for firefox or should it already understand from the g-element it's in?
Apologies for the false alarm, but the problem here (as you can see in my original code) was that I was using the same id on my parent g element as I was to reference my clipPath! I changed the "id" attribute for my clip path to start with the string "clipPath-" and now it works on Firefox. Not sure why that would affect different browsers differently (which is why I kinda went 'round the houses trying to troubleshoot the bug), but thankfully enough it's quite a trivial fix!
I have a rectangle and i am rendering images in it.
I am using clip-rect of Raphael to crop images outside the rectangle area.
At the same time i need to give clip-path to images and rectangle so they can not get outside that particular path.
What Raphael is doing, converting my images clip-rect attribute to clip-path, and then after , overriding that clip-path by the new one.
How can i overcome this problem so my clip-rect and clip-path both works????
Applying clip-rect to elements works for images inside rect and further applying clip-path to that clip-rect which is applied to elements, solves the problem.
<clipPath id="a">
<path..../>
</clipPath>
<clipPath id="b" clip-path="url(#a)">
<rect../>
</clipPath>
<image id="b" clip-path="url(#b)">
