how to set clipPath as a pattern using svg? - svg

I created the pattern, then gave it to the circle inside the . clipPath I set to the image, but the pattern was not set for the image. How can I set a mask as a pattern for an image?
I was expecting to see a mask for the image in the form of a created pattern
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="600" height="600">
<pattern id="cube" x="0" y="10" width="20" height="20" patternUnits="userSpaceOnUse">
<rect x="0" y="0" width="10" height="10" />
<rect x="10" y="10" width="10" height="10" />
</pattern>
<clipPath id="msk1">
<circle fill="url(#cube)" cx="50%" cy="50%" width="100%" height="100%" r="200" />
</clipPath>
<image xlink:href="wave.jpg" height="100%" clip-path="url(#msk1)"/>
</svg>

If you want a mask, then use a <mask>, not a <clipPath>, which as its name implies will create a clipping area from a path. What you want is for the pixels to create the mask, and that's what a <mask> does.
svg { max-height: 100vh }
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 600 600">
<pattern fill="white" id="cube" x="0" y="10" width="20" height="20" patternUnits="userSpaceOnUse">
<rect x="0" y="0" width="10" height="10" />
<rect x="10" y="10" width="10" height="10" />
</pattern>
<mask id="msk1">
<circle fill="url(#cube)" cx="50%" cy="50%" width="100%" height="100%" r="200" />
</mask>
<image xlink:href="https://picsum.photos/400/400" height="100%" mask="url(#msk1)"/>
</svg>
(Note that I did set the rectangles of the pattern white, we could also have drawn a full white rectangle behind the black ones for the same effect).

How to mask a portion of a stroked path in SVG?

I'm looking to mask a portion of a straight line in SVG and can really only figure out how to do it one way, but would rather do another because the line lengths will be dynamically generated and the mask portion won't.
Let me explain.
Assume I have a line that is <path d="M0,0 L0,100" stroke="blue" stroke-width="20"/>, I would like to mask with transparency the first 10 pixels, meaning just the d="M0,0 L0,10" portion.
I can do this, which produces the results I'd like:
<svg width="100" height="100">
<rect stroke="black" stroke-width="2" width="100" height="100" fill="yellow"/>
<svg x="10" y="0" width="200" height="200" >
<defs>
<rect x="0" y="0" width="20" height="10" stroke="none"/>
<mask id="chopmask" maskUnits="userSpaceOnUse">
<rect width="20" height="90" x="0" y="10" fill="white"/>
</mask>
</defs>
<path d="M0,0 L0,100" mask="url(#chopmask)" stroke="blue" stroke-width="20"/>
</svg>
</svg>
But the issue is that I can't seem to do the opposite with the rect in the mask, wherein I simply define the it as <rect width="20" height="10" x="0" y="0" fill="white"/> (notice only height and y are different).
Am I missing something on how do define a 10x20 rectangle and have it's mask simply hide a portion of a stroked path, or is this impossible?
If I understood the question correctly, then you need to have a mask in the form of a rectangle of fixed size 10Х20, which will be applied to the line with variable length.
In this case, you can try on a combined mask, one part of which will be opaque fill = "black" and the second part will be transparent fill = "white" and show the rest of the line.
<svg width="100" height="100">
<rect stroke="black" stroke-width="2" width="100" height="100" fill="yellow"/>
<svg x="10" y="0" width="200" height="200" >
<defs>
<mask id="chopmask" maskUnits="userSpaceOnUse">
<rect width="20" height="100" x="0" y="0" fill="white"/>
<rect width="20" height="10" x="0" y="0" fill="black"/>
</mask>
</defs>
<path d="M0,0 L0,100" mask="url(#chopmask)" stroke="blue" stroke-width="20"/>
</svg>

An example of animating the line masking process with a rectangle 10 x 20px
<svg width="100" height="100">
<rect stroke="black" stroke-width="2" width="100" height="100" fill="yellow"/>
<svg x="10" y="0" width="200" height="200" >
<defs>
<rect x="0" y="0" width="20" height="10" stroke="none"/>
<mask id="chopmask" maskUnits="userSpaceOnUse">
<rect width="20" height="100" x="0" y="0" fill="white"/>
<rect width="20" height="10" x="0" y="0" fill="black">
<animate attributeName="y" dur="2s" values="-10;0" fill="freeze" />
</rect>
</mask>
</defs>
<path d="M0,0 L0,100" mask="url(#chopmask)" stroke="blue" stroke-width="20"/>
</svg>
</svg>
Works for me ... am I misunderstanding what you're trying to do?
<svg width="100" height="100">
<rect stroke="black" stroke-width="2" width="100" height="100" fill="yellow"/>
<svg x="10" y="0" width="200" height="200" >
<defs>
<rect x="0" y="0" width="20" height="10" stroke="none"/>
<mask id="chopmask" maskUnits="userSpaceOnUse">
<rect width="20" height="10" x="0" y="0" fill="white"/>
</mask>
</defs>
<path d="M0,0 L0,100" mask="url(#chopmask)" stroke="blue" stroke-width="20"/>

SVG - how to center a rectangle?

I have a simple SVG with two rectangles. I want the "inner" rectangle to be exactly in the middle of the SVG. By setting x and y attributes to 50% the upper left corner is centred. Instead, I want to center the middle of the rectangle. I've tried setting transform-origin to center but it doesn't work.
<svg width="100" height="100">
<rect width="100%" height="100%" fill="gold" />
<rect width="30" height="30" x="50%" y="50%" fill="green" />
</svg>
How to achieve such functionality without manually specifying x and y attributes?
The explanation of the code:
The x and y coordinates of a rectangle represent the position of the upper left corner. So if you give your rectangle x="50" y="50" this will put the upper left corner of the rectangle in the middle of the SVG canvas. To center the rectangle you need to offset it with half width or height: 50 - (30/2) = 35. The solution is <rect width="30" height="30" x="35" y="35" fill="green" />
<svg width="100" height="100" viewBox="0 0 100 100">
<rect width="100%" height="100%" fill="gold" />
<rect width="30" height="30" x="35" y="35" fill="green" />
</svg>
update:
The op is commenting:
I would actually prefer to set 50% for x and y instead of doing some math
In this case you may need to translate your rect, but you still need some math in order to know how much to translate:
<svg width="100" height="100" viewBox="0 0 100 100">
<rect width="100%" height="100%" fill="gold" />
<rect width="30" height="30" x="50%" y="50%" transform="translate(-15,-15)" fill="green" />
</svg>
<svg width="100" height="100" viewBox="0 0 100 100">
<rect width="100%" height="100%" fill="gold" />
<rect width="30" height="30" x="-15" y="-15" transform="translate(50,50)" fill="green" />
</svg>
Yet an other solution would be using a polygon or a path with the center in the origin:
<svg width="100" height="100" viewBox="0 0 100 100">
<rect width="100%" height="100%" fill="gold" />
<polygon points="-15,-15 15,-15 15,15 -15,15" transform="translate(50,50)" fill="green" />
</svg>
Here is an alternative that may work in some cases:
<svg width="100" height="100" viewBox="0 0 100 100">
<rect width="100%" height="100%" fill="gold" />
<rect width="100%" height="100%" transform-origin="50% 50%" transform="scale(0.3)" fill="green" />
</svg>
You can also do the calculation without the transform attribute.
<svg width="100" height="100" viewBox="0 0 100 100">
<rect width="100%" height="100%" fill="gold" />
<rect width="30" height="30" x="calc(50% - 15)" y="calc(50% - 15)" fill="green" />
</svg>

You could just rotate the <image> by the same amount in the other direction.

But you may find it easier to change the way you do the masking. Don't use a <pattern>, apply a <mask> to an <image> instead.
You can combine rotate and translate into 1 (it will run fast):

Cut off half of the SVG's text element

How can I make this
to look like this
So I want to halve the text element. I don't want to hide half of the text outside of SVG. Hiding it outside of g would be ok, but haven't found solution.
<svg width="500" height="500">
<g transform="translate(50,50)">
<rect width="80" height="50" style="fill:rgb(0,0,255);"/>
<text font-size="40" x="0" y="15" fill="black">SVG</text>
</g>
</svg>
JSFIDDLE:
http://jsfiddle.net/64nkLcdy/
Use the clip-path property :
<svg width="500" height="500">
<defs>
<clipPath id="myClip">
<rect width="80" height="50" />
</clipPath>
</defs>
<g transform="translate(50,50)">
<rect width="80" height="50" style="fill:rgb(0,0,255);" />
<text font-size="40" x="0" y="15" fill="black" clip-path="url(#myClip)">SVG</text>
</g>
</svg>
Use an <svg> element rather than a <g> as the svg element will clip its contents by default. The overflow property controls clipping i.e overflow="visible" doesn't clip but overflow="hidden" does.
<svg width="500" height="500">
<svg transform="translate(50,50)" width="80" height="50" overflow="hidden">
<rect width="80" height="50" style="fill:rgb(0,0,255);"/>
<text font-size="40" x="0" y="15" fill="black">SVG</text>
</svg>
</svg>

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"

</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.
