Calculate SVG.Text Length before drawing [duplicate] - javascript
I want to color the background of svg text similar to background-color in css
I was only able to find documentation on fill, which colors the text itself
Is it even possible?
You could use a filter to generate the background.
<svg width="100%" height="100%">
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow" result="bg" />
<feMerge>
<feMergeNode in="bg"/>
<feMergeNode in="SourceGraphic"/>
</feMerge>
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50">solid background</text>
</svg>
No this is not possible, SVG elements do not have background-... presentation attributes.
To simulate this effect you could draw a rectangle behind the text attribute with fill="green" or something similar (filters). Using JavaScript you could do the following:
var ctx = document.getElementById("the-svg"),
textElm = ctx.getElementById("the-text"),
SVGRect = textElm.getBBox();
var rect = document.createElementNS("http://www.w3.org/2000/svg", "rect");
rect.setAttribute("x", SVGRect.x);
rect.setAttribute("y", SVGRect.y);
rect.setAttribute("width", SVGRect.width);
rect.setAttribute("height", SVGRect.height);
rect.setAttribute("fill", "yellow");
ctx.insertBefore(rect, textElm);
The solution I have used is:
<svg>
<line x1="100" y1="100" x2="500" y2="100" style="stroke:black; stroke-width: 2"/>
<text x="150" y="105" style="stroke:white; stroke-width:0.6em">Hello World!</text>
<text x="150" y="105" style="fill:black">Hello World!</text>
</svg>
A duplicate text item is being placed, with stroke and stroke-width attributes. The stroke should match the background colour, and the stroke-width should be just big enough to create a "splodge" on which to write the actual text.
A bit of a hack and there are potential issues, but works for me!
Instead of using a <text> tag, the <foreignObject> tag can be used, which allows for XHTML content with CSS.
No, you can not add background color to SVG elements. You can do it programmatically with d3.
var text = d3.select("text");
var bbox = text.node().getBBox();
var padding = 2;
var rect = self.svg.insert("rect", "text")
.attr("x", bbox.x - padding)
.attr("y", bbox.y - padding)
.attr("width", bbox.width + (padding*2))
.attr("height", bbox.height + (padding*2))
.style("fill", "red");
Answer by Robert Longson (#RobertLongson) with modifications:
<svg width="100%" height="100%">
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow"/>
<feComposite in="SourceGraphic" operator="xor"/>
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50"> solid background </text>
<text x="20" y="50" font-size="50">solid background</text>
</svg>
and we have no bluring and no heavy "getBBox" :)
Padding is provided by white spaces in text-element with filter.
It's worked for me
Going further with #dbarton_uk answer, to avoid duplicating text you can use paint-order=stroke style:
<svg>
<line x1="100" y1="100" x2="350" y2="100" style="stroke:grey; stroke-width: 100"/>
<text x="150" y="105" style="stroke:white; stroke-width:0.5em; fill:black; paint-order:stroke; stroke-linejoin:round">Hello World!</text>
</svg>
Note the stroke-linejoin:round which is needed to avoid seeing spikes for the W sharp angle.
You can combine filter with the text.
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>SVG colored patterns via mask</title>
</head>
<body>
<svg viewBox="0 0 300 300" xmlns="http://www.w3.org/2000/svg">
<defs>
<filter x="0" y="0" width="1" height="1" id="bg-text">
<feFlood flood-color="white"/>
<feComposite in="SourceGraphic" operator="xor" />
</filter>
</defs>
<!-- something has already existed -->
<rect fill="red" x="150" y="20" width="100" height="50" />
<circle cx="50" cy="50" r="50" fill="blue"/>
<!-- Text render here -->
<text filter="url(#bg-text)" fill="black" x="20" y="50" font-size="30">text with color</text>
<text fill="black" x="20" y="50" font-size="30">text with color</text>
</svg>
</body>
</html>
For those wondering how to apply padding to a text element when it has a background like in the Robert's answer, do the following:
<svg>
<defs>
<filter x="-0.1" y="-0.1" width="1.2" height="1.2" id="solid">
<feFlood flood-color="#171717"/>
<feComposite in="SourceGraphic" operator="xor" />
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50">Hello</text>
</svg>
In the example above, filter's x and y positions can be used as transform: translate(-10%, -10%) would, and width and height values can be read as 120% and 120%. So we made background 20% bigger, and offsetted it -10%, so background is now 10% bigger on each side of the text.
this is my favorite hack (not sure it should work). It refer an element that is not yet displayed, and it works pretty well
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 620 40" preserveAspectRatio="xMidYMid meet">
<defs>
<filter x="-0.02" y="0" width="1.04" height="1.1" id="removebackground">
<feFlood flood-color="#00ffff"/>
</filter>
</defs>
<!--Draw the text-->
<use xlink:href="#mygroup" filter="url(#removebackground)" />
<g id="mygroup">
<text id="text1" x="9" y="20" style="text-anchor:start;font-size:14px;">custom text with background</text>
<line x1="200" y1="18" x2="200" y2="36" stroke="#000" stroke-width="5"/>
<line x1="120" y1="27" x2="203" y2="27" stroke="#000" stroke-width="5"/>
</g>
</svg>
The previous answers relied on doubling up text and lacked sufficient whitespace.
By using atop and I was able to get the results I wanted.
This example also includes arrows, a common use case for SVG text labels:

An obvious workaround to the problem of the blur produced by the filter effect is to render the <text> two times: once for the background (with transparent characters) and once for the characters (without a background filter).
For me, this was the only way to make the text readable in Safari.
<svg width="100%" height="100%">
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow" />
</filter>
<g transform="translate(20, 50)" font-size="50">
<text aria-hidden="true" fill="none" filter="url(#solid)">solid background</text>
<text fill="blue">solid background</text>
</g>
</svg>
The aria-hidden="true" attribute is there to prevent screen readers from speaking the text twice, if the user uses a screen reader.
You can add style to your text:
style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
text-shadow: rgb(255, 255, 255) -2px -2px 0px, rgb(255, 255, 255) -2px 2px 0px,
rgb(255, 255, 255) 2px -2px 0px, rgb(255, 255, 255) 2px 2px 0px;"
White, in this example.
Does not work in IE :)

SVG: Text show to have spacing at top and bottom
I am using a SVG to display a knock-out text template to create a rectangle that has text inside (that comes trough the mask). I want the mask text to match the given size and scale up properly, so that the text in charge does automatically is using the width and height it has for usage. For longer paragraphs this work just fine but when the Text Content is not so long the logic scales up the text to its maximum width/height until it hits a border. See screenshot. But I do see that there is padding that I want to get rid of - how can I make the Text to fit the container fully? To make it better visible I added a Text Element directly to the SVG so I can show the sizes of the Element. How can I get rid of this whitespace? Example with purple boxes that show whitespace in text element This is an example with a longer text that works as expected: <svg id="canvas-6" width="300px" height="75px" viewBox="0 0 300 75" xmlns="http://www.w3.org/2000/svg"> <text transform="translate(0,0)" class="knockout-text-value" id="fit-hidden-6" fill="#000" x="50%" y="50%" width="100%" text-anchor="middle" dominant-baseline="central" font-family="'Lato', sans-serif" font-size="60.785146891139px">TEST TEST</text> <rect id="fit-text-6" class="knockout-text-bg" width="100%" height="100%" fill="red" x="0" y="0" fill-opacity="1" stroke="black" stroke-opacity="1" stroke-width="1" stroke-linecap="round" stroke-dasharray="5,5" mask="url(#knockout-text-6)"></rect> <mask id="knockout-text-6"> <rect width="300px" height="100%" fill="#fff" stroke="#000" stroke-opacity="1" stroke-width="1" stroke-linecap="round" stroke-dasharray="5,5" x="0" y="0"></rect> <text transform="translate(0,0)" class="knockout-text-value" id="fit-mask-6" fill="#000" x="50%" y="50%" text-anchor="middle" dominant-baseline="central" font-family="'Lato', sans-serif" font-size="60.785146891139px">TEST TEST</text> </mask> </svg> This is an example that has the whitespace still inside its SVG canvas: <svg id="canvas-5" width="300px" height="134px" viewBox="0 0 300 134" xmlns="http://www.w3.org/2000/svg"> <text transform="translate(0,0)" class="knockout-text-value" id="fit-hidden-5" fill="#000" x="50%" y="50%" width="100%" text-anchor="middle" dominant-baseline="central" font-family="'Lato', sans-serif" font-size="109.0909090909091px">TEST</text> <rect id="fit-text-5" class="knockout-text-bg" width="100%" height="100%" fill="red" x="0" y="0" fill-opacity="1" stroke="black" stroke-opacity="1" stroke-width="1" stroke-linecap="round" stroke-dasharray="5,5" mask="url(#knockout-text-5)"></rect> <mask id="knockout-text-5"> <rect width="300px" height="100%" fill="#fff" stroke="#000" stroke-opacity="1" stroke-width="1" stroke-linecap="round" stroke-dasharray="5,5" x="0" y="0"></rect> <text transform="translate(0,0)" class="knockout-text-value" id="fit-mask-5" fill="#000" x="50%" y="50%" text-anchor="middle" dominant-baseline="central" font-family="'Lato', sans-serif" font-size="109.0909090909091px">TEST</text> </mask> </svg>

Why does onclick event cause a turn page event in ibook ebook reader?
I am writing an ebook for the apple ibooks app. I am making it an interactive ebook through the use of javascript. I have the javascript working in a browser. And to some degree it works in the apple ibooks app. When I use the onclick event, the function is executed both in the browser and in ibooks. However, in ibooks, it also initiates a page turn event. The onclick event is not seen unless one goes back to the previous page. My javascript is as follows.
//<![CDATA[

//all 12 major keys
var keyArray = ["C","Db","D","Eb","E","F","Gb","G","Ab","A","Bb","B"];

I have tried changing the onclick='changekey("down");' to an ontouchstart and ontouchend event, but those were not recognized within the ibooks app.
The working browser code can be seen here http://jsfiddle.net/slayerofgiants/9772W/1/
And a sample ebook for ibooks can be seen here. The interactive portion is on page 3 and it changes the pages to page 4 or page 2 depending upon which button is tapped. https://www.dropbox.com/s/4x1uex3cbw56c7k/Example.epub
I'm trying to find what is triggering the page turn event and how to disable it for that function.
Thanks,
--christopher
The problem is that your onclick event is also getting passed up to the iBooks application, so it triggers both your code, as well as the default code that handles onclick. If you add return false; to the end of your Javascript function, it should fix it. This thread explains it a bit more.
SVG linking rect in different SVG files and animate them
I search everywhere and I didn't understand/found how to do what I want. I Have 2 svg files who represent somes UML diagrams generated by Visual Paradigm for UML, they have similar objects. For exemple 'FileSource.svg' and 'FileDestination.svg', both of them have an object 'A' who is on differents positions for each. I would like that when you click on 'A' in 'FileSource.svg' that return 'A' in 'FileDestination.svg' with an hightlight on 'A' to see where it's in the diagram 'FileDestination.svg. Here is the jsfiddle : http://jsfiddle.net/jim987/rJk54/ But I don't find how to create 2 files with jsfiddle, so the linking part don't work.. First I tried to link the similar objects, there is the code for one object in diagram : <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE svg PUBLIC '-//W3C//DTD SVG 1.0//EN' 'http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd'> <svg fill-opacity="0" xmlns:xlink="http://www.w3.org/1999/xlink" color-rendering="auto" color-interpolation="auto" stroke="rgb(0,0,0)" text-rendering="auto" stroke-linecap="square" width="1267" stroke-miterlimit="10" stroke-opacity="0" shape-rendering="auto" fill="rgb(0,0,0)" stroke-dasharray="none" font-weight="normal" stroke-width="1" height="626" xmlns="http://www.w3.org/2000/svg" font-family="'Dialog'" font-style="normal" stroke-linejoin="miter" font-size="12" stroke-dashoffset="0" image-rendering="auto"> <defs id="genericDefs"/> <g> <defs id="defs1"> <clipPath clipPathUnits="userSpaceOnUse" id="clipPath7"> <path d="M-7 -7 L101 -7 L101 51 L-7 51 L-7 -7 Z"/> </clipPath> <clipPath clipPathUnits="userSpaceOnUse" id="clipPath10"> <path d="M0 0 L90 0 L90 15 L0 15 L0 0 Z"/> </clipPath> </defs> <g font-size="11" transform="translate(1173,2)" fill-opacity="1" fill="rgb(255,192,255)" text-rendering="geometricPrecision" font-family="sans-serif" stroke="rgb(255,192,255)" font-weight="bold" stroke-opacity="1"> <a xlink:href="FileDestination.svg#A_Object_FileDestination" xlink:title="object definition"> <rect x="0" width="90" height="40" y="0" clip-path="url(#clipPath7)" stroke="none"/> </a> </g> <g font-size="11" stroke-linecap="butt" transform="translate(1173,2)" fill-opacity="1" fill="black" text-rendering="geometricPrecision" font-family="sans-serif" stroke-linejoin="round" stroke="black" font-weight="bold" stroke-opacity="1" stroke-miterlimit="0"> <rect fill="none" x="0" width="90" height="40" y="0" clip-path="url(#clipPath7)"/> </g> <g font-size="11" transform="translate(1173,2)" fill-opacity="1" fill="black" text-rendering="geometricPrecision" font-family="sans-serif" stroke="black" font-weight="bold" stroke-opacity="1"> <a xlink:title="object def"> <text x="21" xml:space="preserve" y="12" clip-path="url(#clipPath10)" stroke="none">Object A</text> </a> <line y2="12" fill="none" x1="21" clip-path="url(#clipPath10)" x2="66" y1="12"/> </g> </g> </svg> Object A in FileDestination.svg : <g font-size="11" transform="translate(712,44)" fill-opacity="1" fill="rgb(255,192,255)" text-rendering="geometricPrecision" font-family="sans-serif" stroke="rgb(255,192,255)" font-weight="bold" stroke-opacity="1"> <rect id="A_Object_FileDestination" x="0" width="90" height="40" y="0" clip-path="url(#clipPath13)" stroke="none"/> </g> The problem is : when I creates this link my rectangle color become black.. do you know why ? Also is it possible to link my object with the transform defined ? (I saw it in the doc) like this : FileDestination.svg#svgView(transform(translate(712,44))) Because I added the id for each rectangle, when svg files are generate there isn't any ids, just the transforms. The translate corresponding at the transform of A in FileDestination, but when I tried it, I just have a blank before my diagram.. And Finally, I have no idea, how to do my animation to target the destination of the link. Certainly in JavaScript or with d3.js ? with actionListener ? but how ? because objects are not in the same page. And I do not how to handle the fact that the objects aren't in the same page. Thanks by advance for yours answers :))
