我试图将PNG或JPG背景图像附加到SVG。目前,在尝试多种不同的附加方法后,背景图像不会显示出来。
我正在使用jQuery.panzoom以及jquery.svg(仅当我需要解决此问题时)。
缩放和平移功能适用于<g>
元素,然后将其中的所有多边形和文本元素移动到一起。我想要的是一个基本上附加到<g>
(或<svg>
)的背景图像,以便在我移动<g>
及其子项时它会移动。 (我知道您无法将背景图像附加到<g>
元素)。
我对SVG元素的基本分组看起来像这样......
<svg id="pnlShapes" width="640" height="480">
<svg id="shapes" width="640" height="480">
<g id="shapes-group" width="640" height="480">
<polygon id="svgSection_Floor" points="222.61,199.75,222.61,295.19,380.62,295.19,380.62,199.75,222.61,199.75,368.46,283.92,233.54,283.92,233.54,209.12,368.46,209.12,368.46,283.92" title="Floor" link="Primary" style="color: rgb(211, 211, 211); font-size: 0px; left: 0px; top: 0px; opacity: 0.82; fill: rgb(211, 211, 211); cursor: not-allowed;"></polygon>
<text x="302.61" y="289.4705" fill="white" font-size="9" font-weight="bold" text-anchor="middle">Floor</text>
<!-- plus a bunch more polygon and text element... -->
</g>
</svg>
</svg>
我尝试使用图案填充来附加背景图片。 jsFiddle
<svg id="pnlShapes" width="640" height="480">
<defs xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:svg="http://www.w3.org/2000/svg">
<pattern id="image" x="0" y="0" patternunits="userSpaceOnUse" height="480" width="640">
<image x="0" y="0" width="640" height="480" xlink:href="http://localhost:44000/Content/images/theImage.jpg"></image>
</pattern>
</defs>
<svg id="shapes" width="640" height="480" fill="url(#image)">
<g id="shapes-group" width="640" height="480">
<polygon id="svgSection_Floor" points="222.61,199.75,222.61,295.19,380.62,295.19,380.62,199.75,222.61,199.75,368.46,283.92,233.54,283.92,233.54,209.12,368.46,209.12,368.46,283.92" title="Floor" link="Primary" style="color: rgb(211, 211, 211); font-size: 0px; left: 0px; top: 0px; opacity: 0.82; fill: rgb(211, 211, 211); cursor: not-allowed;"></polygon>
<text x="302.61" y="289.4705" fill="white" font-size="9" font-weight="bold" text-anchor="middle">Floor</text>
</g>
</svg>
</svg>
我也尝试使用 jquery.svg 附加背景图片jsFiddle:
$('#shapes').svg();
var foo = $('#shapes').svg('get');
foo.filters.image(null, '', "http://localhost:44000/Content/images/theImage.jpg");
<小时/> 这是我的锅&amp; amp;缩放代码(使用jquery.panzoom),如果有帮助:
var $section = $('#svg-container').first();
$section.find('g').panzoom({
$zoomIn: $section.find(".zoom-in"),
$zoomOut: $section.find(".zoom-out"),
$zoomRange: $section.find(".zoom-range"),
$reset: $section.find(".reset")
});
如果使用插件是实现这一目标的最佳方式,那么我使用它没有问题。我只需要在<svg id="shapes">
或其内部或<g>
元素上有背景图片。

SVG不支持CSS背景图片。你可以通过创建一个占据整个空间的<rect>
元素作为第一个孩子来模拟它,但
<svg id="pnlShapes" width="640" height="480">
<defs>
<pattern id="image" patternUnits="userSpaceOnUse" height="480" width="640">
<image width="640" height="480" xlink:href="https://octodex.github.com/images/octoliberty.png"></image>
</pattern>
</defs>
<svg id="shapes" width="640" height="480">
<rect width="100%" height="100%" fill="url(#image)"/>
<g id="shapes-group">
<polygon id="svgSection_Floor" points="222.61,199.75,222.61,295.19,380.62,295.19,380.62,199.75,222.61,199.75,368.46,283.92,233.54,283.92,233.54,209.12,368.46,209.12,368.46,283.92" title="Floor" link="Primary" style="color: rgb(211, 211, 211); font-size: 0px; left: 0px; top: 0px; opacity: 0.82; fill: rgb(211, 211, 211); cursor: not-allowed;"></polygon>
<text x="302.61" y="289.4705" fill="white" font-size="9" font-weight="bold" text-anchor="middle">Floor</text>
</g>
</svg>

SVG确实支持CSS背景图片。对于上面的代码,您可以通过说:
将背景图像添加到<svg id="pnlShapes">
<!DOCTYPE html>
<html>
<head>
<style>
#pnlShapes {
background-image: url('https://octodex.github.com/images/octoliberty.png');
background-repeat: no-repeat;
background-size: contain;
background-position: center;
}
</style>
</head>
<body>
<svg id="pnlShapes" width="640" height="480">
<svg id="shapes" width="640" height="480">
<g id="shapes-group" width="640" height="480">
<polygon id="svgSection_Floor" points="222.61,199.75,222.61,295.19,380.62,295.19,380.62,199.75,222.61,199.75,368.46,283.92,233.54,283.92,233.54,209.12,368.46,209.12,368.46,283.92" title="Floor" link="Primary" style="color: rgb(211, 211, 211); font-size: 0px; left: 0px; top: 0px; opacity: 0.82; fill: rgb(211, 211, 211); cursor: not-allowed;"></polygon>
<text x="302.61" y="289.4705" fill="white" font-size="9" font-weight="bold" text-anchor="middle">Floor</text>
<!-- plus a bunch more polygon and text element... -->
</g>
