SVG路径绘制和图像填充

Question

我需要一点帮助理解/编辑一些svg路径。我协助绘制了三个相同的三角形（里面有图像），我想将前两个三角形改为一个连续的平行四边形。我已经玩了数吨，最终得到了我想要的形状，但图像总是重复在路径所画的形状中间的一条线上。我改变了图像的纵横比，但无济于事。谁能告诉我我做错了什么？这里是一个例子jsFiddle和我的代码。

我想要什么，但需要平行四边形与中间三角形高度相同（从而完全覆盖它），并且我需要它不会重复图像。从教育的角度来看，对这些不同的.attr如何影响事物的任何解释都会很有帮助。

var width = 800; 
var height = 200; 


var svg = d3.select(".mydiv").append("svg") 
          .attr("width",width) 
          .attr("height",height) 
          .attr("viewBox", "0 0 250 100"); 

var defs= svg.append('defs') 
defs.append('pattern') 
    .attr('id', 'pic1') 
    .attr('patternUnits', 'userSpaceOnUse') 
    .attr('width', 115.5) 
    .attr('height', 100) 
    .append('svg:image') 
    .attr('xlink:href', 'http://francomasoma.com/wp-content/uploads/2016/05/FullSizeRender_7-560x483.jpg') 
    .attr("width", 115.5) 
    .attr("height", 100) 
    .attr("x", 0) 
    .attr("y", 0); 


    defs.append('pattern') 
    .attr('id', 'pic2') 
    .attr('patternUnits', 'userSpaceOnUse') 
    .attr('width', 115.5) 
    .attr('height', 100) 
    .append('svg:image') 
    .attr('xlink:href', 'http://wire.kapitall.com/wp-content/image-import/92277513-560x483.jpg') 
    .attr("width", 115.5) 
    .attr("height", 100) 
    .attr("x", 0) 
    .attr("y", 0); 


    defs.append('pattern') 
    .attr('id', 'pic3') 
    .attr('patternUnits', 'userSpaceOnUse') 
    .attr('width', 115.5) 
    .attr('height', 100) 
    .append('svg:image') 
    .attr('xlink:href', 'http://gallery.ksotov.co.uk/main.php?g2_view=core.DownloadItem&g2_itemId=13225&g2_serialNumber=1') 
    .attr("width", 115.5) 
    .attr("height", 100) 
    .attr("x", 0) 
    .attr("y", 0); 



svg.append("a") 
    .append('path') 
    .attr("d", "M 0,0, 57.7,-100, 115.5,0z") 
    .attr("transform", "translate(135.5, 100)") 
    .attr("fill", "url(#pic1)"); 

svg.append("a") 
    .append('path') 
    .attr("d", "M 57.7,0, 0,-100, 115.5,-100z") 
    .attr("transform", "translate(67.7, 100)") 
    .attr("fill", "url(#pic2)"); 

svg.append("a") 
    .append('path') 
    .attr("d", "M 0,0, 57.7,-100, 183,-100, 125.5,0") 
    .attr("transform", "translate(0, 100)") 
    .attr("fill", "url(#pic3)");

一种方法是简单地使用patternTransform来缩放图像。我也调整了高度以确保它的放置正确。

var width = 800; 
 
var height = 200; 
 
    
 

 
var svg = d3.select(".mydiv").append("svg") 
 
          .attr("width",width) 
 
          .attr("height",height) 
 
          .attr("viewBox", "0 0 250 100"); 
 

 
var defs= svg.append('defs') 
 
defs.append('pattern') 
 
    .attr('id', 'pic1') 
 
    .attr('patternUnits', 'userSpaceOnUse') 
 
    .attr('width', 115.5) 
 
    .attr('height', 100) 
 
    .append('svg:image') 
 
    .attr('xlink:href', 'http://francomasoma.com/wp-content/uploads/2016/05/FullSizeRender_7-560x483.jpg') 
 
    .attr("width", 115.5) 
 
    .attr("height", 100) 
 
    .attr("x", 0) 
 
    .attr("y", 0); 
 

 

 
    defs.append('pattern') 
 
    .attr('id', 'pic2') 
 
    .attr('patternUnits', 'userSpaceOnUse') 
 
    .attr('width', 115.5) 
 
    .attr('height', 100) 
 
    .append('svg:image') 
 
    .attr('xlink:href', 'http://wire.kapitall.com/wp-content/image-import/92277513-560x483.jpg') 
 
    .attr("width", 115.5) 
 
    .attr("height", 100) 
 
    .attr("x", 0) 
 
    .attr("y", 0); 
 

 

 
    defs.append('pattern') 
 
    .attr('id', 'pic3') 
 
    .attr('patternUnits', 'userSpaceOnUse') 
 
    .attr('width', 115.5) 
 
    .attr('height', 75) 
 
    .attr('patternTransform', "scale(2)") 
 
    .append('svg:image') 
 
    .attr('xlink:href', 'http://gallery.ksotov.co.uk/main.php?g2_view=core.DownloadItem&g2_itemId=13225&g2_serialNumber=1') 
 
    .attr("width", 115.5) 
 
    .attr("height", 100) 
 
    .attr("x", 0) 
 
    .attr("y", 0); 
 

 

 

 
svg.append("a") 
 
    .attr("xlink:href", "http://www.google.com") 
 
    .append('path') 
 
    .attr("d", "M 0,0, 57.7,-100, 115.5,0z") 
 
    .attr("transform", "translate(135.5, 100)") 
 
    .attr("fill", "url(#pic1)"); 
 

 
svg.append("a") 
 
    .attr("xlink:href", "http://www.wikipedia.com") 
 
    .append('path') 
 
    .attr("d", "M 57.7,0, 0,-100, 115.5,-100z") 
 
    .attr("transform", "translate(67.7, 100)") 
 
    .attr("fill", "url(#pic2)"); 
 

 
svg.append("a") 
 
    .attr("xlink:href", "#testanchor") 
 
    .append('path') 
 
    .attr("d", "M 0,0, 57.7,-100, 183,-100, 125.5,0") 
 
    .attr("transform", "translate(0, 100)") 
 
    .attr("fill", "url(#pic3)");
