SVG Positioning

Everything in the g element is positioned relative to the current transform matrix. To move the content, just put the transformation in the g element: <g transform=”translate(20,2.5) rotate(10)”> <rect x=”0″ y=”0″ width=”60″ height=”10″/> </g> Links: Example from the SVG 1.1 spec

How to place multiple evenly-spaced arrowheads along an SVG line?

Based on a clarification of the question, here’s an implementation of creating intermediary points along a <polyline> element such that the marker-mid=”url(#arrowhead)” attribute will work. See below that for an introduction to markers and arrowheads.

SVG shadow cut off

You need to increase the size of the filter region. <filter id=”SVGID_0″ y=”-40%” height=”180%”> works just fine. The silent defaults for the filter region are: x=”-10%” y=”-10%” width=”120%” height=”120%” – large blurs usually get clipped. (Your shadow isn’t getting clipped horizontally because your width is about 2.5x your height – so that 10% results in … Read more

vertical alignment of text element in SVG

According to SVG spec, alignment-baseline only applies to <tspan>, <textPath>, <tref> and <altGlyph>. My understanding is that it is used to offset those from the <text> object above them.

You need … Read more

Default background color of SVG root element

SVG 1.2 Tiny has viewport-fill I’m not sure how widely implemented this property is though as most browsers are targetting SVG 1.1 at this time. Opera implements it FWIW. A more cross-browser solution currently would be to stick a <rect> element with width and height of 100% and fill=”red” as the first child of the … Read more

Find svg viewbox that trim whitespace around

You can simply set your svg’s viewBox to its Bounding Box. function setViewbox(svg) { var bB = svg.getBBox(); svg.setAttribute(‘viewBox’, bB.x + ‘,’ + bB.y + ‘,’ + bB.width + ‘,’ + bB.height); } document.querySelector(‘button’).addEventListener(‘click’, function() { setViewbox(document.querySelector(‘svg’)); }); svg { border: 1px solid } <svg version=”1.1″ id=”svg” xmlns=”http://www.w3.org/2000/svg” xmlns:xlink=”http://www.w3.org/1999/xlink” x=”0px” y=”0px” viewBox=”0 0 500 300″ … Read more
