reference element in a animate element and the element and animate element are in a defs to be reflected in use element - svg

I am researching svg animation and was wonder if it possible to use the href attribute in the animate element which the target of the href and the animate element it self are in a defs... here is a code working example:
<svg viewBox="0 0 400 100">
<defs>
<rect id="anim-rect"
x="-25" y="-25"
width="50" height="50"
fill="#29e" >
<animate
attributeName="fill"
values="#29e; #4e4; #f40; #29e"
dur="6s"
repeatCount="indefinite" />
</rect>
</defs>
<use xlink:href="#anim-rect" transform="translate(100 50)"/>
<use xlink:href="#anim-rect" transform="translate(200 50)"/>
<use xlink:href="#anim-rect" transform="translate(300 50)"/>
</svg>
And here what I want to do:
<svg viewBox="0 0 400 100">
<defs>
<rect id="anim-rect"
x="-25" y="-25"
width="50" height="50"
fill="#29e" >
</rect>
<animate xlink:href="#anim-rect"
attributeName="fill"
values="#29e; #4e4; #f40; #29e"
dur="6s"
repeatCount="indefinite" />
</defs>
<use xlink:href="#anim-rect" transform="translate(100 50)"/>
<use xlink:href="#anim-rect" transform="translate(200 50)"/>
<use xlink:href="#anim-rect" transform="translate(300 50)"/>
</svg>
Any help would be appreciated.

How to add animation in the clippath of svg

I'm learning how to use svg clippath. And I know how to use the static clippath.
<svg width="500" height="150">
<clipPath id="circle">
<circle cx=50 cy=50 r=50></circle>
</clipPath>
<circle cx=50 cy=50 r=50></circle>
<rect x="0" y="0" width="30" height="15"
style="stroke: #ff0000; fill: none;" clip-path='url(#circle)'>
</rect>
</svg>
there I can get a clip rect.
code Image
but when I try to add an animation, the rect could out of the clippath.
<svg width="500" height="150">
<clipPath id="circle">
<circle cx=50 cy=50 r=50></circle>
</clipPath>
<circle cx=50 cy=50 r=50></circle>
<rect x="0" y="0" width="30" height="15"
style="stroke: #ff0000; fill: none;" clip-path='url(#circle)'>
<animateMotion
path="M10,50 q60,50 100,0 q60,-50 100,0"
begin="0s" dur="10s" repeatCount="indefinite"
rotate="auto"
></animateMotion>
</rect>
</svg>
The rect is out of clippath
what I need is when the rect is out of clippath, it could not be seen any more. The clippath is not allow to move.
So how to get the rectangle in motion to remain in the clippath?
You put the clipped rect in a group and you apply the animation to the group like so:
<svg viewBox="0 0 400 300">
<clipPath id="circle">
<circle cx=50 cy=50 r=50>
</circle>
</clipPath>
<g>
<circle cx=50 cy=50 r=50></circle>
<rect x="0" y="0" width="30" height="15"
style="stroke: #ff0000; fill: none;" clip-path='url(#circle)'>
</rect>
<animateMotion
path="M10,50 q60,50 100,0 q60,-50 100,0"
begin="0s" dur="10s" repeatCount="indefinite"
rotate="auto"
></animateMotion>
</g>
</svg>
UPDATE
The OP is commenting that his question has now been revised.
My question is how to not show the rectangle when it moves outside the clippath?
In this case you put the animated rect in a group and you clip the group like so:
<svg viewBox="0 0 500 150">
<clipPath id="circle">
<circle cx=50 cy=50 r=50></circle>
</clipPath>
<g clip-path='url(#circle)'>
<circle cx=50 cy=50 r=50></circle>
<rect x="0" y="0" width="30" height="15"
style="stroke: #ff0000; fill: none;" >
<animateMotion
path="M10,50 q60,50 100,0 q60,-50 100,0"
begin="0s" dur="10s" repeatCount="indefinite"
rotate="auto"
></animateMotion>
</rect>
</g>
</svg>

Displacement map filter not working on rotated object

I am trying to make mirrored pattern, but when I add displacement filter, it seems it only works on first and fourth quandrant. Am I overlooking some beginner mistake or is this behavior expected?
<svg width="500px" height="500px">
<defs>
<clipPath id="clip">
<rect x="0" y="0" width="50%" height="50%"/>
</clipPath>
<pattern id="diagonalHatch" patternUnits="userSpaceOnUse" width="4" height="4" patternTransform="scale(20) rotate(0)">
<path d="M-1,1 l2,-2
M0,4 l4,-4
M3,5 l2,-2"
style="stroke:red; stroke-width:1" />
</pattern>
<symbol id="quarter">
<rect x="0" y="0" width="100%" height="100%" fill="url(#diagonalHatch)" clip-path="url(#clip)"/>
</symbol>
<filter id="noise" x="0%" y="0%" width="100%" height="100%">
<feTurbulence baseFrequency="0.02" numOctaves="3" result="noise" seed="3" />
<feDisplacementMap in="SourceGraphic" in2="noise" scale="8" />
</filter>
</defs>
<g filter="url(#noise)">
<use xlink:href="#quarter"/>
<use xlink:href="#quarter" style="transform-origin: 50% 50%;" transform="rotate(90)"/>

<use xlink:href="#quarter" style="transform-origin: 50% 50%;" transform="rotate(270)"/>
</g>
</svg>
In your filter I've added xChannelSelector="R" for the feDisplacementMap. I'm using R for red since your shapes are red.
<filter id="noise" x="0%" y="0%" width="100%" height="100%">
<feTurbulence baseFrequency="0.02" numOctaves="3" result="noise" seed="3" />
<feDisplacementMap in="SourceGraphic" in2="noise" scale="8" xChannelSelector="R" />
</filter>
<svg width="500px" height="500px">

<path d="M-1,1 l2,-2

<symbol id="quarter">
<rect x="0" y="0" width="100%" height="100%" fill="url(#diagonalHatch)" clip-path="url(#clip)"/>
</symbol>
<filter id="noise" x="0%" y="0%" width="100%" height="100%">
<feTurbulence baseFrequency="0.02" numOctaves="3" result="noise" seed="3" />
<feDisplacementMap in="SourceGraphic" in2="noise" scale="8" xChannelSelector="R" />
</filter>
</defs>
<g filter="url(#noise)">
<use xlink:href="#quarter"/>
<use xlink:href="#quarter" style="transform-origin: 50% 50%;" transform="rotate(90)"/>
<use xlink:href="#quarter" style="transform-origin: 50% 50%;" transform="rotate(180)"/>
<use xlink:href="#quarter" style="transform-origin: 50% 50%;" transform="rotate(270)"/>
</g>
</svg>
Also I would have applied the filter to the <rect> inside <symbol> instead of applying it to the group.
You're just missing an xChannelSelector or yChannelSelector - one of which is required.
(Update - as you mention in the comment, when you leave this out, it defaults to using the alpha channel in both X and Y - so it will shift everything up and down the top/left bottom/right diagonal axis - so solid color diagonal lines with this orientation will only show distortions at their starting and finishing edges).
If you're not going to process the feTurbulence in some way after you generate it, then any one of the channels (RGBA) works as a displacement source - since Perlin noise is equally noisy in all four channels.
(You don't need to use the R channel because your shapes are red - that's backwards - the channel selector applies to your noise input, not your the shape you want to apply it to.)

How can i scale a shape without scaling its pattern?

I have an svg shape which uses a pattern. I want the pattern to NOT scale when i scale the shape.
Here's a fiddle with a minimal example, the bigger circle should show the pattern like the smaller one:
http://jsfiddle.net/cTMrQ/6/
<svg style="position: absolute" width="100%" height="100%" version="1.1" baseProfile="full" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:ev="http://www.w3.org/2001/xml-events">
<defs>
<pattern id="checkerPattern" patternUnits="userSpaceOnUse" x="0" y="0" width="4" height="4">
<image x="0" y="0" xlink:href="http://inwonderland.at/new/lines.png" width="4" height="4" />
</pattern>
<circle fill="url(#checkerPattern)" id="c" cx="50" cy="50" r="50" />
</defs>
<use x="100" y="100" xlink:href="#c" />
<use x="200" y="100" xlink:href="#c" transform="scale(2)" />
</svg>
In the end the shape will be a complex path and the image in the pattern will be a scan of a piece of paper, so just drawing a bigger circle instead of scaling it won't work.
Update
To clarify what i want, here are two images:
this is what it looks like, no matter what i try, when i scale the shape:
http://inwonderland.at/new/ihave.png
this is what i want:
http://inwonderland.at/new/iwant.png
i want the background image (bitmap image) to always have its natural size.
You can't get what you want using a pattern, the transform always happens after the fill, and you can't just move the pattern fill into a wrapper either. My suggestion is to use a filter and apply the filter on a wrapper - like so:
<svg style="position: absolute" width="100%" height="100%" version="1.1" baseProfile="full" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:ev="http://www.w3.org/2001/xml-events">
<defs>
<circle fill="url(#checkerPattern)" id="c1" cx="50" cy="50" r="50" />
<filter id="linepattern" x="0%" y="0%" height="100%" width="100%">
<feImage xlink:href="http://inwonderland.at/new/lines.png" result="pattern" width="4" height="4"/>
<feTile/>
<feComposite operator="in" in2="SourceGraphic"/>
</filter>
</defs>
<use filter="url(#linepattern)" x="100" y="100" xlink:href="#c1" />
<use filter="url(#linepattern)" x="200" y="100" xlink:href="#c1" transform="scale(2)" />
<g filter="url(#linepattern)">
<use x="50" y="100" xlink:href="#c1" transform="scale(2)" />
</g>
</svg>
Using viewport
1:1 no zoom
<svg width="800" height="400" viewBox="0 0 800 400">
2:1 zoom double size
<svg width="800" height="400" viewBox="0 0 400 200">
The following elements can use the viewBox attribute
<svg>
<symbol>
<image>
<marker>
<pattern>
<view>
viewbox is fully animatable; and you can zoom into any center point.
<animate attributeName="viewBox" begin="1s" dur="1s"
values="0 0 600 400; 250 180 300 200" fill="freeze" />
Transform a parent tag
Yes an SVG can be a child element but more commonly shapes made with multible tags are placed inside a group tag.
Transform scale can be used with tags which are parents IE the group tag.
<g transform="scale(1.5)">
/* draw your shape inside the g tag */
<use x="100" y="100" xlink:href="#c" />
<use x="200" y="100" xlink:href="#c" />
</g>
So using your above example scale the shape in a parent tag.
Update
To scale image but not patterns in other words move patterns, or icons, on background image that scales.
<g transform="scale(2)">
/* draw your shape inside the g tag */
<use x="100" y="100" xlink:href="#c" transform="scale(.5)" />
<use x="200" y="100" xlink:href="#c" transform="scale(.5)"/>
</g>
Update full svg
I had to move things around a bit, One full size, (lets call it a map), with an overlay of 1 half size map in the upper left corner. setting the full screen to render between 0 and max of 600. Setting a viewport the same but with the width set to 300 scales it down. I do need to double the radius for this example of scaling.
<svg viewBox="0 0 600 600" style="position: absolute" width="100%" height="100%" version="1.1" baseProfile="full"
xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:ev="http://www.w3.org/2001/xml-events">
<defs>
<pattern id="checkerPattern" patternUnits="userSpaceOnUse" x="0" y="0" width="4" height="4">
<image x="0" y="0" xlink:href="http://inwonderland.at/new/lines.png" width="4" height="4" />
</pattern>
<circle fill="url(#checkerPattern)" id="c" cx="50" cy="50" r="50" />
<circle fill="url(#checkerPattern)" id="c2" cx="50" cy="50" r="100" />
</defs>
<use x="100" y="100" xlink:href="#c" transform="scale(.5)"/>
<use x="200" y="100" xlink:href="#c" transform="scale(1)"/>
<rect width="600" height="600" style="fill: none; stroke: black;" />
<svg viewBox="0 0 600 600" width="300" height="300" x="300">
<use x="100" y="100" xlink:href="#c2" transform="scale(.5)"/>
<use x="200" y="100" xlink:href="#c2" transform="scale(1)"/>
<rect width="600" height="600" style="fill: none; stroke: black;" />
</svg>
</svg>
This example is scaled using the same circle pattern. The radius does not need to be changed here because the location is not in the tag being scaled. I'm making use of svg tags here but other tags can be used.
<svg viewBox="0 0 600 600" style="position: absolute" width="100%" height="100%" version="1.1" baseProfile="full"
xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:ev="http://www.w3.org/2001/xml-events">
<defs>
<pattern id="checkerPattern" patternUnits="userSpaceOnUse" x="0" y="0" width="4" height="4">
<image x="0" y="0" xlink:href="http://inwonderland.at/new/lines.png" width="4" height="4" />
</pattern>
<circle fill="url(#checkerPattern)" id="c" r="50" cx="50" cy="50" />
</defs>
<svg x="100" y="100"><use xlink:href="#c" transform="scale(.5)"/></svg>
<svg x="200" y="100"><use xlink:href="#c" transform="scale(1)"/></svg>
<rect width="600" height="600" style="fill: none; stroke: black;" />
<svg viewBox="0 0 600 600" width="300" height="300" x="300">
<svg x="100" y="100"><use xlink:href="#c" transform="scale(1)"/></svg>
<svg x="200" y="100"><use xlink:href="#c" transform="scale(2)"/></svg>
<rect width="600" height="600" style="fill: none; stroke: black;" />
</svg>

Avoiding the clipping of symbols in SVG

For my use it would be convenient for me to have a list of SVG symbols centered on zero, making their placement with use easier. For example a symbol which is simply a circle would have its center at zero and then a given radius. However with the standard clipping that clips away 3/4 of the circle. Here's an example:
<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
version="1.1" width="400.0" height="400.0" preserveAspectRatio="xMidYMid meet"
viewBox="0.0 0.0 230.0 150.0">
<rect x="0.0" y="0.0" width="230.0" height="150.0" style="stroke:#000000; stroke-width:0.5 ; fill:#B9FFFF;"/>
<symbol id="concentric">
<circle cx="0.0" cy="0.0" r="10.0" style="stroke:#FF0000; stroke-width:0.266; fill:none"/>
<circle cx="0.0" cy="0.0" r="5.0" style="stroke:#00FF00; stroke-width:0.266; fill:none"/>
</symbol>
<use xlink:href="#concentric" x="20" y="20" />
<use xlink:href="#concentric" x="40" y="20" />
<use xlink:href="#concentric" x="60" y="20" />
</svg>
This will result in three uses of the symbol called "concentric" but since the original symbol has two circles at 0,0 three quarters of the symbol is clipped.
What is the easiest way of not clipping the symbols at 0 0?
You can use overflow="visible" to turn clipping off if you don't want it.
<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
version="1.1" width="400.0" height="400.0" preserveAspectRatio="xMidYMid meet"
viewBox="0.0 0.0 230.0 150.0">
<rect x="0.0" y="0.0" width="230.0" height="150.0" style="stroke:#000000; stroke-width:0.5 ; fill:#B9FFFF;"/>
<symbol id="concentric" overflow="visible">
<circle cx="0.0" cy="0.0" r="10.0" style="stroke:#FF0000; stroke-width:0.266; fill:none"/>
<circle cx="0.0" cy="0.0" r="5.0" style="stroke:#00FF00; stroke-width:0.266; fill:none"/>
</symbol>
<use xlink:href="#concentric" x="20" y="20" />
<use xlink:href="#concentric" x="40" y="20" />
<use xlink:href="#concentric" x="60" y="20" />
</svg>

How to Exclude Area inside of clippath in Svg

I want to hide anything that outside a rectangle. (this i have achieved with clipping successfully). but another condition is that, 'also hide anything that comes inside the black big circle'. Now how i can achieve that?
in below example, 'yellow circle' must be eliminated'.
see below images for detail
Original:-
Desired:-
Below is my Svg code:-
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="500" height="500">
<g>
<rect x="50" y="50" width="200" height="200" stroke="1" fill="red"/>
<circle cx="180" cy="150" r="30" stroke="blue" />
</g>
<g clip-path = "url(#clip1)">
<circle cx="180" cy="150" r="10" stroke="blue" fill="yellow" />
</g>
<clipPath id = "clip1">
<rect x="50" y="50" width="200" height="200" stroke="1" fill="red"/>
</clipPath>
</svg>
Erik Dahlström is right, your clip can include the entire rectangle and the cutout for the circle. This way, anything you associate with #clip1 as the clip-path will not be visible inside your circle area. Here is what it looks like for your example:
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="500" height="500">
<g>
<rect x="50" y="50" width="200" height="200" stroke="1" fill="red"/>
<circle cx="180" cy="150" r="30" stroke="blue" />
</g>
<g clip-path = "url(#clip1)">
<circle cx="180" cy="150" r="10" stroke="blue" fill="yellow" />
</g>
<clipPath id = "clip1">
<path d="M 50,50 l200 0 l0 200 l-200 0z M150,150 a30,30 1 0,0 60,0z M210,150 a30,30 1 0,0 -60,0z"/>
</clipPath>
