This is my first time using SVG so apologies if this is a stupid question but I am trying to create a clickable continent map on my site and have acquired an SVG image with the continents mapped out correctly from wikipedia.
http://commons.wikimedia.org/wiki/File:Continents.svg
However, this image is 585 x 299 pixels and I require an image that is 292 x 137 pixels. I've read online that these images are scalable and that all you need to do is modify the width and height value in the svg definition so I have done so here:
<svg width="292" height="137" xmlns="http://www.w3.org/2000/svg" xmlns:svg="http://www.w3.org/2000/svg" preserveAspectRatio="xMidYMid meet">
However, this only scales the canvas as such and does not scale the internal areas. How do I get the areas to scale to the modified dimensions of the image?
The SVG will be any size you tell it to in the CSS
CSS
svg {
width:292px;
height:137px;
border:1px solid grey
}
This works with or without the dimensions stated in the SVG. the important item is the 'viewbox' which sets the co-ordinate structure for the SVG.
到目前为止,我发现的唯一方法是将我的所有区域都包裹在一个标签中,并且它们应用
<g transform="scale(0.68)">
Add a viewBox attribute (viewBox="0 0 585 299" is probably what you want) to the svg element. We can simulate what that would look like by using a fragment identifier which will impose a viewBox on the original file eg
http://upload.wikimedia.org/wikipedia/commons/9/95/Continents.svg#svgView(viewBox(0,0,529,290))
That sure displays differently in Firefox.
Use a viewBox like this :
<svg
xmlns="http://www.w3.org/2000/svg"
version="1.0"
width="292pt" height="137pt"
viewBox="0 0 468 239"
preserveAspectRatio="xMidYMid meet"
>
<g
transform="translate(0,239) scale(0.016963,-0.016963)"
fill="#000000"
stroke="none"
