I have svg mask which determines holes in rectangular. Behind svg mask I have some clickable elements and I would like to pass events to them, but only through holes.
I've already asked this question here and got an answer, which worked perfectly for me until I've run into a case with intersecting rectangulars
Click only through holes in svg mask
Is there any simple solution to got area around rectangulars clipped out but not area in intersections? It would be perfect to have something like globalCompositeOperation='destination-out' and I've started to think of how to use canvas instead of svg for my problem, but pointer-events which I use for svg are not yet designed to work correct with canvas as far as I know.
button, svg {
position:absolute;
width:400px;
height:400px
}
button {
background: #0000ff;
cursor: pointer;
}
button:hover {
background: #008800;
}
svg {
pointer-events: none;
}
.over {
fill: #000;
clip-path: url(#clip);
pointer-events: painted;
}
<button></button>
<svg xmlns="http://www.w3.org/2000/svg" height="400" width="400">
<defs>
<clipPath id="clip" clip-rule="evenodd">
<path d="M 20 20 h 360 v 360 h -360 z
M 90 100 v 240 h 140 v -240 z
M 200 290 v 80 h 80 v -80 z" />
</clipPath>
</defs>
<rect y="0" x="0" height="400" width="400" class="over" />
</svg>
In my view, this is a problem of convenience. You would like to be able to use separate paths and treat them the same way whether they interact or not. Unfortunately, because of some limitations in the system, I do not think it is possible to achieve this convenience. However, your quetion itself is easy to answer.
First, a word about what is going on in your example. Your clipPath has a large "outer" path that is drawn clockwise (right, down, left, up). Then you have two "inner" paths drawn counterclockwise (down, right, up, left). The clip works according to what is considered inside and outside the path. The problem is that the intersection is considered outside (see link).
The straightforward solution is to use a single path for every shape, even if it is not a simple rectangle:
button, svg {
position:absolute;
width:400px;
height:400px
}
button {
background: #0000ff;
cursor: pointer;
}
button:hover {
background: #008800;
}
svg {
pointer-events: none;
}
.over {
fill: #000;
clip-path: url(#clip);
pointer-events: painted;
}
<button></button>
<svg xmlns="http://www.w3.org/2000/svg" height="400" width="400">
<defs>
<clipPath id="clip" clip-rule="evenodd">
<path d="M 20 20 h 360 v 360 h -360 z
M 90 100 v 240 h 110 v 30 h 80 v -80 h -50 v -190 z" />
</clipPath>
</defs>
<rect y="0" x="0" height="400" width="400" class="over" />
</svg>
Is there any way to resample a raster picture inside an <image> tag that itself is inside a <svg> container after I scale (transform) the container?
I have a 640x640px jpeg. It looks like this on the page (it's a popup on a map that enlarges on hover).
<svg class="photo" style="top: 425px; left: 1406px;">
<image width="64" height="64" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="../images/someimg.jpg"></image>
</svg>
css:
.photo {
position: absolute;
width: 54px;
height: 54px;
transform-origin: 50% 119%;
box-shadow: 5px 5px 3px #999;
overflow: visible;
cursor: pointer;
}
.photo image {
clip-path: url(#clipper);
}
clipped by
<svg>
<defs>
<clipPath id="clipper">
<polygon points="0,0 56,0 56,56 36,56 28,64 20,56 0,56 0,0"/>
</clipPath>
</defs>
</svg>
Previously I tried css scaling:
photo:hover {
transform: scale(2.5);
}
it worked great: the <image> inside looked sharp after the transform, but hover itself looked ugly when interrupted. So I tried to do it with d3.transition()
$photoSvg.on('mouseover', function() {
d3.select(this).transition()
.duration(400)
.style('transform', 'scale(2.5)');
})
.on('mouseout', function() {
d3.select(this).transition()
.duration(400)
.style('transform', 'scale(1)');
});
There is a strange effect now. When I first hover after the page reload there is no transition but the svg scales and the <image> looks kind of sharp. But on consecutive transitions I see the animation but the image is sharp only when it is small. When it is scaled 2.5 times it looks just like a stretched image from scale(1).
Any light shed would be much appreciated.
Thanks.
I am trying to crop background image with custom form.. but I have stacked with that.
The goal is to crop image like this:
Think of every step like it is different html pages (page-1.html, page-2.html, page-3.html).
In the page-1.html background is pretty simple. The important think to admit - this pictures have to be responsive.
page-1.html
background-image: url(image-1.jpg) no-repeat 50% 0;
background-size: cover;
The second example can be done by using <svg> elements.
page-2.html
<svg id="bigTriangleColor" xmlns="http://www.w3.org/2000/svg" version="1.1" width="100%" height="200" viewBox="0 0 100 102" preserveAspectRatio="none" class="triangle-svg">
<path d="M0 100 L50 0 L100 100 Z"></path>
</svg>
<style>
.triangle-svg {
position: absolute;
left: 0;
right: 0;
top: auto;
bottom: 0;
z-index: 999;
fill: #fff;
}
</style>
But what about third example? I don't know how to deal with it.
In 3 example we see something like:
<div class='top-layout'></div>
<div class='bottom-layout'></div>
The .top-layout image should be croped. The <svg> decision is bad because we should able to put second image uderneeth the first.
.top-layout {
height: 500px;
}
.bottom-layout {
height: 500px;
position: relative;
top: -150px;
}
And all this stuff should be responsive with background-size: conver effect.
#phrogz deserve all the credits since he answered first.
Demo of clip-path, mask and gradient. For your solution, replace the contents of group <g clip-path="url(#clip-bottom)" > ... </g> with your own <image .... clip-path="url(#clip-bottom)" />. Usually I'd create a group with clip-path to keep the image tag cleaner, but that's my own preference.
I have embedded an svg file into an html file and can view it in all browsers and platforms. I now want to make specific paths within the svg clickable. I have used an onclick event to perform this function, however, I have only been able to get a javascript alert box to popup when the path is clicked. Instead of the default javascript alert, I need a custom popup which I can then include unique custom text and a hyperlink url for each of the paths. Therefore, each path would have its own text and hyperlink.
Does anyone know the best/easiest way to accomplish this?

Add a custom attribute to each of your paths to store the URL you want to open:
<path d="M10,60 L50,10 90,60" data-url="http://www.google.com/" />
Then access this URL in your event handler:
var url = evt.target.getAttribute('data-url');
Then open a popup window with that URL:
window.open(url);
So the complete script becomes:
function notify(evt){
var url = evt.target.getAttribute('data-url');
window.open(url);
}
If I am right in that your need is for something like alert("xxx") which can contain any HTML...
There's 3 parts: a style, a div and a function to show the popup
<style>
#popupInfo
{
visibility: hidden;
position: absolute;
top: 100px;
left: 100px;
width: auto;
height:auto;
margin-left: 5px;
z-index: 5;
background-color: #ffffff;
padding: 0px;
border: 1px solid #a0a0a0;
border-radius: 10px;
box-shadow: 1px 3px 2px rgba(20,20,20,0.3);
}
#closeButton
{
position: absolute;
width: 32px;
height: 32px;
background: transparent url(X_light.gif);
right: 5px;
top: 5px;
}
#closeButton:hover
{
background: url(X_dark.gif);
z-index: 99;
}
</style>
<body>
<div id="popupInfo"">
<div id="closeButton" onclick="document.getElementById('popupInfo').style.visibility = 'hidden';"></div>
<table style="width:100%;">
<tr style="height:32px;"><td ></td></tr>
<tr><td id="popupInfoText"></td></tr>
</table>
</div>
...
<script type="text/javascript">
function popupInfo(newtext, width, height){
var popStyle= document.getElementById("popupInfo").style
if( width ) popStyle.width=width.toString()+'px';
if( height ) popStyle.height=height.toString()+'px';
document.getElementById("popupInfoText").innerHTML = newtext;
popStyle.visibility = 'visible';
}
</script>
The "X_light.gif" and "X_dark.gif" are 32x32pixel grey X's on transparent used as the Close button.
A call to e.g. popupInfo("<H1>Alert!</H1>This is a message!"); will show the message.
To get an html document from a file you could do it several ways, if they are fixed files then you could:
popupInfo("<IFRAME src='message.html'></IFRAME>");
where message.html is like:
<H1>Hello there!</H1>
<p>This is a test message</p>
The result being:
...a nice image that I can't post as a guest :(
Enjoy!

I have a series of svg rectangles (using D3.js) and I want to display a message on mouseover, the message should be surrounded by a box that acts as background. They should both be perfectly aligned to each other and to the rectangle (on top and centered). What is the best way to do this?
I tried adding an svg text using the "x", "y", "width" and "height" attributes, and then prepending an svg rect. The problem is that the reference point for the text is in the middle (since I want it centered aligned I used text-anchor: middle), but for the rectangle it's the top left coordinate, plus I wanted a bit of margin around the text which makes it kind of a pain.
The other option was using an html div, which would be nice, because I can add the text and padding directly but I don't know how to get the absolute coordinates for each rectangle. Is there a way to do this?
Can you use simply the SVG <title> element and the default browser rendering it conveys? (Note: this is not the same as the title attribute you can use on div/img/spans in html, it needs to be a child element named title)
rect {
width: 100%;
height: 100%;
fill: #69c;
stroke: #069;
stroke-width: 5px;
opacity: 0.5
}
<p>Mouseover the rect to see the tooltip on supporting browsers.</p>
<svg xmlns="http://www.w3.org/2000/svg">
<rect>
<title>Hello, World!</title>
</rect>
</svg>
Alternatively, if you really want to show HTML in your SVG, you can embed HTML directly:
rect {
width: 100%;
height: 100%;
fill: #69c;
stroke: #069;
stroke-width: 5px;
opacity: 0.5
}
foreignObject {
width: 100%;
}
svg div {
text-align: center;
line-height: 150px;
}
<svg xmlns="http://www.w3.org/2000/svg">
<rect/>
<foreignObject>
<body xmlns="http://www.w3.org/1999/xhtml">
<div>
Hello, <b>World</b>!
</div>
</body>
</foreignObject>
</svg>
…but then you'd need JS to turn the display on and off. As shown above, one way to make the label appear at the right spot is to wrap the rect and HTML in the same <g> that positions them both together.
To use JS to find where an SVG element is on screen, you can use getBoundingClientRect(), e.g. http://phrogz.net/svg/html_location_in_svg_in_html.xhtml
The only good way I found was to use Javascript to move a tooltip <div> around. Obviously this only works if you have SVG inside an HTML document - not standalone. And it requires Javascript.
function showTooltip(evt, text) {
let tooltip = document.getElementById("tooltip");
tooltip.innerHTML = text;
tooltip.style.display = "block";
tooltip.style.left = evt.pageX + 10 + 'px';
tooltip.style.top = evt.pageY + 10 + 'px';
}
function hideTooltip() {
var tooltip = document.getElementById("tooltip");
tooltip.style.display = "none";
}
#tooltip {
background: cornsilk;
border: 1px solid black;
border-radius: 5px;
padding: 5px;
}
<div id="tooltip" display="none" style="position: absolute; display: none;"></div>
<svg>
<rect width="100" height="50" style="fill: blue;" onmousemove="showTooltip(evt, 'This is blue');" onmouseout="hideTooltip();" >
</rect>
</svg>
You can use the title element as Phrogz indicated. There are also some good tooltips like jQuery's Tipsy http://onehackoranother.com/projects/jquery/tipsy/ (which can be used to replace all title elements), Bob Monteverde's nvd3 or even the Twitter's tooltip from their Bootstrap http://twitter.github.com/bootstrap/
On svg, the right way to write the title
<svg>
<title id="unique-id">Checkout</title>
</svg>

I always go with the generic css title with my setup. I'm just building analytics for my blog admin page. I don't need anything fancy. Here's some code...
let comps = g.selectAll('.myClass')
.data(data)
.enter()
.append('rect')
...styling...
...transitions...
...whatever...
g.selectAll('.myClass')
.append('svg:title')
.text((d, i) => d.name + '-' + i);
And a screenshot of chrome...
I use heroicons for the project I am working on. (This is JSX format) I will handle the tooltip issue with this code.
<svg className="h-6 w-6">
<title>{reasons.join(" ")}</title>
<QuestionMarkCircleIcon className={style} />
</svg>
