Stroke of both <use> element ignored here. The stroke color of <circle> is set blue which is appearing on both <use> element too. Why?
I want different strock color of all of 3 these element. but it is not working.
<svg width="300" class="svg-elem" viewBox="0 0 30 10" xmlns="http://www.w3.org/2000/svg">
<circle id="myCircle" cx="5" cy="5" r="4" stroke="blue"/>
<use class="circle1" href="#myCircle" x="10" stroke="grey" fill="blue"/>
<use href="#myCircle" x="20" fill="white" stroke="red"/>
</svg>
Because circle still overriding the <use>.
You can consider using CSS variable to control stroke color like below.
<svg width="300" class="svg-elem" viewBox="0 0 30 10" xmlns="http://www.w3.org/2000/svg">
<circle id="myCircle" cx="5" cy="5" r="4" style="stroke:var(--stroke, blue)"/>
<use class="circle1" href="#myCircle" x="10" style="--stroke:gray;" fill="blue"/>
<use href="#myCircle" x="20" fill="white" style="--stroke:red;"/>
</svg>
I have two shapes: circle and rectangle. Want to convert them into one figure. Are there any ways to do that in SVG code?
<svg width="400" height="400">
<defs>
<g id="shape" fill="none" stroke="red">
<rect x="40" y="50" width="40" height="70" />
<circle cx="50" cy="50" r="50" />
</g>
</defs>
<use xlink:href="#shape" x="50" y="50" />
<use xlink:href="#shape" x="200" y="50" />
</svg>
Like this:
For anyone looking for the answer to the actual question of how to combine two outlined shapes into a single outlined shape (rather than putting a drop shadow on the combined shape), here is a possible solution:
<svg width="400" height="400">
<defs>
<rect id="canvas" width="100%" height="100%" fill="white" />
<rect id="shape1" x="40" y="50" width="40" height="70" />
<circle id="shape2" cx="50" cy="50" r="50" />
<mask id="shape1-cutout">
<use href="#canvas" />
<use href="#shape1" />
</mask>
<mask id="shape2-cutout">
<use href="#canvas" />
<use href="#shape2" />
</mask>
</defs>
<use href="#shape1" stroke="red" fill="none" mask="url(#shape2-cutout)" />
<use href="#shape2" stroke="red" fill="none" mask="url(#shape1-cutout)" />
</svg>
This essentially draws the circle with the rectangle shape cut out of it and draws the rectangle with the circle cut out of it. When you place these "punched out" shapes one on top of the other, you get what appears to be a single outlined shape.
Here's what the SVG actually does:
It defines a white rectangle called "canvas" that is the same size as the SVG.
It defines the two shapes that are to be combined ("shape1" and "shape2").
It defines a mask for each shape that combines the canvas (which has a fill of white) with the shape (which has a fill of black by default). Note that when you apply a mask to a shape, the part of the shape that corresponds to the white area of the mask is shown, while the part that corresponds with black part is hidden.
It draws each shape with the the mask of the other shape applied.
You can make a <mask> or a <clipPath> from the two shapes and then use that to mask a third shape. You can then apply your drop shadow to that.
<svg width="400" height="400">
<defs>
<clipPath id="shape">
<rect x="40" y="50" width="40" height="70" />
<circle cx="50" cy="50" r="50" />
</clipPath>
<filter id="shadow">
<feGaussianBlur in="SourceAlpha" stdDeviation="3"/>
<feOffset dx="3" dy="3"/>
<feMerge>
<feMergeNode/>
<feMergeNode in="SourceGraphic"/>
</feMerge>
</filter>
</defs>
<g filter="url(#shadow)">
<rect width="100%" height="100%" fill="red"
clip-path="url(#shape)"/>
</g>
</svg>
Note: if you are wondering why we are applying the drop shadow to a parent <g> here, it is because if we applied it directly to the <rect>, the drop shadow would be subject to the clip also.
What's wrong with just a dropshadow on a group around the shapes?
<svg width="400" height="400">
<defs>
<filter id="shadow">
<feGaussianBlur in="SourceAlpha" stdDeviation="3"/>
<feOffset dx="3" dy="3"/>
<feMerge>
<feMergeNode/>
<feMergeNode in="SourceGraphic"/>
</feMerge>
</filter>
</defs>
<g filter="url(#shadow)">
<rect x="40" y="50" width="40" height="70" fill="red"/>
<circle cx="50" cy="50" r="50" fill="red"/>
</g>
</svg>
Note: Be aware that this solution is only giving you the outer part of the contour.
A little variation of #devuxer's answer. A shadow can be created by a mask that can then be applied to a black shape. In https://stackoverflow.com/a/50884092/275195 two masks are created with set theory (A-B)+(B-A). However in the rendering engine a pixel raster is used for masks and antialiasing is applied. This leads to half-transparent pixels in the mask at the boundary of A and B. This can be avoided by applying the shaped to one mask like this (basically outline of A+B minus A+B):
<svg>
<!-- Masks seem to be pre-filled with black -->
<mask id="union">
<!-- Whatever is white in the mask will be visible of the shape the mask is applied to. -->
<rect id="A" x="20" y="20" width="50" height="100" stroke="white" fill="none"></rect>
<!-- Putting a second (, third, ...) shape into the mask will draw the shape over any existing shapes. -->
<circle id="B" cx="80" cy="60" r="30" stroke="white" fill="none"></circle>
<!-- Now we delete the inner part of the shapes by drawing black over them. -->
<rect id="Ainner" x="20" y="20" width="50" height="100" fill="black"></rect>
<circle id="Binner" cx="80" cy="60" r="30" fill="black"></circle>
</mask>
<!-- Applied to a full-screen red rectangle it cuts out the strokes from the mask. -->
<rect id="A+B" x="0" y="0" width="100%" height="100%" fill="red" mask="url(#union)"></rect>
</svg>
For everyone who wants both fill and border, here is a combination of devuxers and pascals posts
<svg width="500" height="300" xmlns="http://www.w3.org/2000/svg">
<defs>
<rect id="canvas" width="100%" height="100%" fill="white" />
<rect id="rect" x="50" y="60" width="40" height="70" />
<circle id="circle" cx="50" cy="50" r="40" />
<clipPath id="shape">

<use href="#circle" />
</clipPath>
<mask id="maskRect">
<use href="#canvas" />
<use href="#rect" />
</mask>
<mask id="maskCircle">
<use href="#canvas" />

<use href="#circle" stroke="green" stroke-width="2" fill="none" mask="url(#maskRect)" />
</svg>
With the feMorphology filter you can grow and shrink objects (MDN). Combining them, you can create a simply reusable outline: make an increased copy of the original, paint it, and place it under the shrunk original.
<svg xmlns="http://www.w3.org/2000/svg" width="400" height="400">
<defs>
<filter id="outline">
<!-- Make a copy of the original,
grow it by half the stroke width,
call it outer -->
<feMorphology
operator="dilate"
radius="1"
result="outer"
/>
<!-- Make another copy of the original,
shrink it by half the stroke width,
call it inner -->
<feMorphology
in="SourceGraphic"
operator="erode"
radius="1"
result="inner"
/>
<!-- Create a color layer... -->
<feFlood
flood-color="black"
flood-opacity="1"
result="outlineColor"
/>
<!-- ...and crop it by outer -->
<feComposite
operator="in"
in="outlineColor"
in2="outer"
result="coloredOuter"
/>
<!-- Place the shrunk original over it -->
<feComposite
operator="over"
in="inner"
in2="coloredOuter"
/>
</filter>
</defs>
<g filter="url(#outline)">
<rect x="50" y="60" width="40" height="70" fill="red" />
<circle cx="60" cy="60" r="50" fill="red" />
</g>
</svg>
If you want to have it transparent, replace the operator in the last feComposite with xor:
<!-- Knock off the shrunk one -->
<feComposite
operator="xor"
in="inner"
in2="coloredOuter"
/>
The only caveat: fatter strokes - ie larger dilate and erode radii - on curves may look distorted, with 1px + 1px it is still fine.
I'm trying to figure out how to add a unique prefix to ID's and other reference links.
I have multiple identical SVGs on a page. These SVGs serve as a wrapper (they're devices - laptop, phone, etc.) which have image link that is inserted into the SVG after load. The problem is, the ID's for these svgs are identical so they all conflict with each other. What I'm trying to do (but am open to better solutions) is to insert a unique ID to each id,xlink:href, url(#, etc. but pass over the <image> href attribute and fill and stroke attributes.
EDIT: I added/tweaked the code provided by #Temani, which got me closer to my desired result, however, I'm now getting all the ID's added to each SVG element. Formatted the code to be executable.
Desired output:
<div class="device" data-screen="[[IMAGE TO USE]]" data-name"[[UNIQUE ID]]">
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="635" height="420" viewBox="0 0 635 420">
<defs>
<path id="[[UNIQUE ID]]-path-1"/>
<rect id="[[UNIQUE ID]]-path-3" />
<pattern id="[[UNIQUE ID]]-pattern-4">
<use transform="scale(13.1875)" xlink:href="#[[UNIQUE ID]]-image-5"/>
</pattern>
<image id="[[UNIQUE ID]]-image-5" href="[[IMAGE LINK THAT IS INSERTED AFTER LOAD]]"/>
</defs>
<g fill="none" fill-rule="evenodd">
<rect fill="#fff" stroke="#2D8EFF" />
<g >
<mask id="[[UNIQUE ID]]-mask-2" fill="#fff">
<use xlink:href="#[[UNIQUE ID]]-path-1"/>
</mask>
<g mask="url(#[[UNIQUE ID]]-mask-2)">
<mask id="mask-6" fill="#fff">
<use xlink:href="#[[UNIQUE ID]]-path-3"/>
</mask>
</g>
</g>
</g>
</svg>
</div>
Right now - both ID's (first and second) gets added to each SVG element. I also
$('.device').each(function() {
//we get the needed id using $(this) that refer to actual device
var id = $(this).data('name');
//we check all the element with ID
$(this).find("path, rect, pattern, image, mask").each(function() {
//now (this) refer to the actual element
if($(this).attr("id"))
$(this).attr("id", id+"-"+$(this).attr("id"));
});
//we update the <use>
$(this).find("use").each(function() {
//now (this) refer to the actual element
$(this).attr("xlink:href","#"+id+"-"+$(this).attr("xlink:href").substring(1));
});
// Also, hoping to combine g[mask], u[fill], etc into 1 function.
// Basically any attribute that starts with "url(#"
$(this).find("g[mask^='url']").each(function() {
$(this).attr("mask","url(#"+id+"-"+$(this).attr("mask").substring(5));
});
$(this).find("use[fill^='url']").each(function() {
$(this).attr("fill","url(#"+id+"-"+$(this).attr("fill").substring(5));
});
$(this).find("use[filter^='url']").each(function() {
$(this).attr("filter","url(#"+id+"-"+$(this).attr("filter").substring(5));
});
// grab data-screen value
var data = $(this).data('screen');
// replace this with the link inside svg
if (data != '') {
$(this).find("svg defs image").attr("href", data).attr("xlink:href", data);
}
});

The issue is that you don't have to use $('.device') when inside and you need to refer to $(this) and since you have 2 each() nested you need to pay attention to the scope of this.
$('.device').each(function() {
//we get the needed id using $(this) that refer to actual device
var id = $(this).data('name');
//we check all the element with ID
$(this).find("path, rect, pattern, image, mask").each(function() {
//now (this) refer to the actual element
if($(this).attr("id"))
$(this).attr("id", id+"-"+$(this).attr("id"));
});
//we update the <use>
$(this).find("use").each(function() {
//now (this) refer to the actual element
$(this).attr("xlink:href","#"+id+"-"+$(this).attr("xlink:href").substring(1));
});
// grab data-screen value
var data = $(this).data('screen');
// replace this with the link inside svg
if (data != '') {
$(this).find("svg defs image").attr("href", data).attr("xlink:href", data);
}

I get a much greater rectangle than I would expect in Firefox.
When I inspect the objects, the displayed bounding box for the inner svg element is fine, but the surrounding g element (class nodeicon) is outside.
If I remove this g element, the next surrounding g element is outside.
The following picture shows this:
It looks like the offset of the svg is applied twice.
Is getBoundingClientRect the correct way to get the position and size of elements (e.g. the g element with class nodes) for this? Is there something wrong with the HTML or svg element or did I run into a Firefox bug?
I am using the current version of Firefox (58.0 64bit).
A problem that you have here is that the svg tag nested inside the g tag (.nodeicon) is starting a new viewport context. Strictly speaking it should not be nested inside a g tag anyway, but regardless, it isn't really necessary as you're using it as a method of grouping the two elements inside it - which is the purpose of the g tag.
Try removing the svg tag nested inside .nodeicon, and move the coordinates in that svg's x and y attributes to a transform attribute on the g tag.
i.e:
<g class="nodeicon" transform="translate(80, 68)">
<rect height="14" width="14" y="1" x="1" stroke="#888888" stroke-width="1" fill="#ffffff" fill-opacity="0.5"></rect>
<line x1="4" y1="8" x2="12" y2="8" stroke="#888888" stroke-width="2"></line>
</g>
I have the following SVG code. The SVG with id "nestedsvg" is being appended in the HTML, I can view it on the console. But it's not visible on the screen. I tried assigning it a z-index of 99 but still it's invisible. Where am I going wrong?
<svg data="BusinessRoleFigure" x="144" y="95"
width="128" height="66" id="outer" style="position: relative;">
<rect x="0" y="0" width="100%" height="100%"

This is because the rectangle you are drawing is outside of the nested SVG viewport.
That SVG has a width and height of 100x50, and you are drawing a 20x10 rectangle at (-50,0). Meaning the rectangle covers the area from (-50,0) to (-30,10). So it is not visible. By default, objects outside a nested SVG viewport are not visible.
There are two ways to fix this:
Make objects outside the viewport visible. You can do this by setting overflow="visible" on the nested SVG.
<svg data="BusinessRoleFigure" x="144" y="95" width="128" height="66" id="outer">
<rect x="0" y="0" width="100%" height="100%" stroke="rgb(178,178,126)" stroke-width="1" fill="rgb(255,255,181)"></rect>
<svg id="nestedsvg" x="100%" height="100" width="50" overflow="visible">
<rect x="-50" rx="5" ry="5" width="20" height="10" stroke="black" stroke-width="1" fill="black"></rect>
</svg>
<circle cx="118" cy="13" r="5" fill="none" stroke-linejoin="round" stroke="black" stroke-width="1"></circle>
</svg>
Move the rectangle inside the SVG viewport and reposition the SVG so that the rectangle ends up in the same place.
I don't know why you wanted the nested SVG to be at x="100%", but you would need to change that if you go with this solution.
<svg data="BusinessRoleFigure" width="128" height="66" id="outer">
<rect x="0" y="0" width="100%" height="100%" stroke="rgb(178,178,126)" stroke-width="1" fill="rgb(255,255,181)"></rect>
<svg id="nestedsvg" x="78" height="100" width="50">
<rect x="0" rx="5" ry="5" width="20" height="10" stroke="black" stroke-width="1" fill="black"></rect>
</svg>
<circle cx="118" cy="13" r="5" fill="none" stroke-linejoin="round" stroke="black" stroke-width="1"></circle>
</svg>
A few other notes about your original SVG:
x and y coordinates on the root <svg> element have no effect.
z-index currently has no meaning in SVGs. Although this may change for the upcoming SVG2 standard.
position: relative has no meaning in SVGs.
I've removed these things from my modified examples.
