I am working on svg rectangles which represent a farmer's field. Is it possible to have an image of a field on it, just to give it a true sense and view.
Here's a sample code of one of the rectangles
<!DOCTYPE html>
<html>
<body>
<svg width="400" height="110">
<rect width="300" height="100" style="fill:green; stroke: black; stroke-width:3;" />
</svg>
</body>
</html>
I used clipPath to cut and place the picture in a rectangle.
<svg width="600" height="200" viewBox="0 0 600 200" >
<defs>
<clipPath id="field">
<rect x="25" y="5" width="550" height="190" rx="25" ry="25" style="fill:none; stroke: black; stroke-width:1;" />
</clipPath>
</defs>
<image xlink:href=" https://i.stack.imgur.com/MJkK0.jpg" width="600" height="200" clip-path="url(#field)" />
</svg>
If you want to use a different border form instead of a rectangle, for example a circle, then this will be easy to do, replacing the rectangle with a circle in the clipPath.
Option, as suggested by Paulie_D, but it needs a little refinement
If you need a frame around the picture, you will need to add a second transparent rectangle with a border
<rect width="300" height="100" style="fill:none; stroke: black; stroke-width:3;" />
<svg width="400" height="110">
<defs>
<pattern id="field" patternUnits="userSpaceOnUse" width="300" height="100">
<image xlink:href=" https://i.stack.imgur.com/MJkK0.jpg" x="-20" y="0" width="350" height="130" />
</pattern>
</defs>
<rect width="300" height="100" fill="url(#field)" />
<rect width="300" height="100" style="fill:none; stroke: black; stroke-width:3;" />
</svg>
UPDATE
With a black frame looks grim, let's replace it with a shadow.
To create a shadow, the Gauss filter is used, blurring the edges of the bottom rectangle
<filter id="filtershadow" width="120%" height="120%">
<feGaussianBlur in="SourceAlpha" stdDeviation="4"/>
</filter>
<body>
<svg width="400" height="110">
<defs>
<filter id="filtershadow" width="120%" height="120%">
<feGaussianBlur in="SourceAlpha" stdDeviation="4"/>
</filter>
<pattern id="field" patternUnits="userSpaceOnUse" width="300" height="100">
<image xlink:href=" https://i.stack.imgur.com/MJkK0.jpg" x="0" y="0" width="350" height="130" />
</pattern>
</defs>
<rect class="rect-shadow" x="10" y="14" width="290" height="90" filter="url(#filtershadow)" style="fill:black; " />
<rect width="300" height="100" fill="url(#field)" />
</svg>
</body>

I have an svg with a mask. Another element uses the mask as such:
mask="url(#mask)"
While trying to satisfy this: Treat '#' as ending data URI body content
I changed my svg mask to "url(%23mask)", but that totally breaks the mask.
Does anyone know a solution to this issue? Is there a way to satisfy both chrome and the mask?
Code snippet below contains two identical svg's; the only difference is that one uses a # and the other uses %23 when defining their urls.
I want to display the text over the svg rect. Text is hidden in the sample. I want full text as visible :
<svg width="400" height="110">
<rect width="300" height="100" style="fill:white;stroke-width:3;stroke:rgb(0,0,0);"/>
<text x="10" y="35" fill="red">I love SVG! Text Chart</text>
</svg>
<svg height="300" width="60" style="position:absolute;left:20px;top:20px">
<rect width="300" height="50" style="fill:yellow;stroke-width:3;stroke:rgb(0,0,0);"/>
</svg>
Here is the updated code:-
<svg width="400" height="110">
<rect width="300" height="100" style="fill:white;stroke-width:3;stroke:rgb(0,0,0);"/>
</svg>
<svg height="300" width="1000" style = "position:absolute;left:20px;top:20px">
<rect width="60" height="60" style="fill:yellow;stroke-width:3;stroke:rgb(0,0,0);"/>
<text x="10" y="35" fill="red">I love SVG! Text Chart</text>
</svg>
I'm starting to learn JS and i have this (probably very easy) task that I'm having problems with.
So the main task is to make the lower green triangle change it's color depending on which color i click on upper object.
I made something like this:
<!DOCTYPE html>
<html><head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>SVG, JavaScript</title>
<script type="text/javascript">
function changeColor("triangle"){
document.getElementById("group").getAttributeNS("fill");
evt.target.setAttributeNS("fill");
}
</script>
</head>
<body>
<svg height="500" width="500">
<g id="group">
<rect x="0" y="0" width="200" height="200" style="fill:gray;stroke:none;stroke-width:0"/>
<rect id="red_triangle" x="0" y="0" width="100" height="100" style="fill:red;stroke:none;stroke-width:0"/>
<rect id="yellow_triangle"x="100" y="0" width="100" height="100" style="fill:yellow;stroke:none;stroke-width:0"/>
<rect id="blue_triangle"x="0" y="100" width="100" height="100" style="fill:blue;stroke:none;stroke-width:0v"/>
<rect id="green_triangle"x="100" y="100" width="100" height="100" style="fill:lime;stroke:none;stroke-width:0"/>
<ellipse cx="100" cy="100" rx="100" ry="100" style="fill:gray;stroke:none;stroke-width:0"/>
<polygon id="triangle" points="100,225 150,300 50,300" style="fill:lime;stroke:none;stroke-width:0" onclick="changeColor("triangle")"/>
</g>
</svg>
</body>
</html>
but obviously it's not working. Could somebody help me with some suggestion?
// the string instead of argument name raises Error: unexpected string
function changeColor("triangle"){
// you get the attribute but don't do anything with it.
// and the group doesn't even have a fill attribute
document.getElementById("group").getAttributeNS("fill");
// here you try to set an attribute but setAttributeNS requires 3 arguments: namespace, attribute and value
// simpler setAttribute would be enough, but the value would still be overwriten by style="fill:whatever"
// and evt.target is undefined, there's no evt object
evt.target.setAttributeNS("fill");
}
then in your SVG:
// the quotes are broken,
// and here you pass a string which I'd assume to be the ID of an element you want to change
onclick="changeColor("triangle")"
So, all in all:
The onclick should be on the source rectangles, not the target triangle: <rect onclick="changeColor('triangle', this)" /> where 'triangle' is the ID of element you want to change, and this is a reference to the clicked rectangle.
SVG:
<svg height="500" width="500">
<g id="group">
<rect x="0" y="0" width="200" height="200" style="fill:gray;stroke:none;stroke-width:0"/>
<rect id="red_triangle" x="0" y="0" width="100" height="100" style="fill:red;stroke:none;stroke-width:0" onclick="changeColor('triangle', this)"/>
<rect id="yellow_triangle"x="100" y="0" width="100" height="100" style="fill:yellow;stroke:none;stroke-width:0" onclick="changeColor('triangle', this)"/>
<rect id="blue_triangle"x="0" y="100" width="100" height="100" style="fill:blue;stroke:none;stroke-width:0v" onclick="changeColor('triangle', this)"/>
<rect id="green_triangle"x="100" y="100" width="100" height="100" style="fill:lime;stroke:none;stroke-width:0" onclick="changeColor('triangle', this)"/>
<ellipse cx="100" cy="100" rx="100" ry="100" style="fill:gray;stroke:none;stroke-width:0"/>
<polygon id="triangle" points="100,225 150,300 50,300" style="fill:lime;stroke:none;stroke-width:0" />
</g>
</svg>
JS:
function changeColor( target, source ){
var color = source.style.fill;
document.getElementById( target ).style["fill"] = color;
}

Is it possible to shade in a corner of a shape using only gradients?
Below is an image of what I am trying to do, but had to use a circle and a path.
I know using a path is probably a better method, but I am curious if it can be accomplished with gradients.
Thank you.
Path is not the only method. Sometimes a 5 year old can outsmart me with basic shapes:-
<svg class="sheet" xmlns="http://www.w3.org/2000/svg"
xlink="http://www.w3.org/1999/xlink" version="1.1" width="200" height="200">
<pattern id="my_pattern" patternUnits="userSpaceOnUse"
width="200" height="200" viewbox="0 0 200 200">
<rect x="0" y="0" fill="#33ff33" width="200" height="200" />
<rect x="50" y="0" fill="red" width="50" height="50" />
</pattern>
<circle cx="50" cy="50" r="40" style="stroke:black; stroke-width: 2;
fill: URL(#my_pattern)"/>
</svg>
Not with a single gradient. No.
After several tries, and code changes, I am unable to make rectangle inside SVG to change his position - don't even ask for animating. Obviously using jQuery SVG plugin plus animation extension.
The problem: A SVGs wrapped inside three <div>, an inside y have a rectangle that need to be at y:0 after the document loads. And this is the code:
var rect = jQuery('div.post-image').children('svg').svg().svg('get');
jQuery(rect).each(function(){
jQuery(this).change('.b1', {y:0});
});
Well, nothing happens with the rectangle, it keeps the original coordinate. Chrome console doesn't says anything either.
Added: the HTML in question

<feGaussianBlur stdDeviation="7" result="offset-blur"></feGaussianBlur>
<feComposite operator="out" in="SourceGraphic" in2="offset-blur" result="inverse"></feComposite>
<feFlood flood-color="#000" flood-opacity="0.3" result="color"></feFlood>
<feComposite operator="in" in="color" in2="inverse" result="shadow"></feComposite>

</clipPath>
</defs>
<polygon points="0,0 235,0 250,70 235,140 0,140 15,70" style="fill: url(#image-771); filter:url(#innershadow);"></polygon>
<rect class="b1" width="100%" height="100%" style="fill:rgb(0,92,148); opacity: 0.9;" clip-path="url(#clip)" x="0" y="98"></rect>
<rect class="b2" width="60" height="25" style="fill:rgb(0,92,148); opacity: 0.9;" clip-path="url(#clip)" x="190" y="0"></rect>
<rect class="b3" width="100" height="25" style="fill:rgb(0,0,0); opacity: 0.75;" clip-path="url(#clip)" x="0" y="0"></rect>
</g>
<foreignObject width="250" height="140">
<img width="250" height="125" src="example-fallback.jpg" alt="example" title="title"> </foreignObject>
</switch>
</svg>
</a>
I'm willing to use <canvas> for this, but I don't know what are the outcomes.
Found out what wast the problem:
var rect = jQuery('a.post-image').children('svg').find('.b2, .b3');
jQuery(rect).each(function(){
jQuery(this).attr('y','-25');
});
Done, and without a plugin. Okey, not the best way (find instead of most direct selector), but it will cut it.
