我正在使用我的项目fabricJS,我有改变笔触颜色和宽度的问题。我的页面上有一些SVG文件,单击用户后可以将此SVG添加到画布并修改其属性。填充它完美的工作,但中风我不能这样做。这是填充代码,它运作良好:
function setImageColor(element)
{
var activeObject = canvas.getActiveObject(),
color = "#"+element.value;
console.log(color)
console.log(activeObject)
activeObject.set({fill : color});
canvas.renderAll();
}
jscolor.addEventListener('change', function()
{
setImageColor(this);
});
以下是在画布上加载SVG元素的代码:
shapes.forEach(function(e)
{
e.addEventListener("click", function()
{
var src = e.src;
fabric.loadSVGFromURL( src, function(objects, options)
{
var obj = fabric.util.groupSVGElements(objects, options);
canvas.add(obj).renderAll();
obj.scaleToHeight(127)
.scaleToWidth(90)
.center()
.setCoords();
canvas.setActiveObject(obj).renderAll();
});
});
});
这里是笔划的代码,它不起作用:
function setStrokeColor(element)
{
color = "#"+element.value;
var obj = canvas.getActiveObject();
console.log(color)
console.log(activeObject)
activeObject.set({stroke : color, strokeWidth: 5});
canvas.renderAll();
}
var stroke = document.getElementById("stroke");
console.log(stroke)
stroke.addEventListener('change', function()
{
setStrokeColor(this);
});
答案 0 :(得分:1)
这应该这样做(感谢SVG路径导出):
这是FabricJS代码:
fabric.loadSVGFromString('<svg id="Warstwa_1" data-name="Warstwa 1" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 70 70"><defs><style>.cls-1{fill:none;stroke:#000;stroke-miterlimit:10;}</style></defs><title>generator ikon</title><path class="cls-1" d="M60,35A25,25,0,1,1,35,10,25,25,0,0,1,60,35Z"/></svg>', function(objects, options) {
var shape = fabric.util.groupSVGElements(objects, options);
shape.set({
left: 50,
top: 50,
scaleX: 3,
scaleY: 3
});
if (shape.paths) {
for (var i = 0; i < shape.paths.length; i++) {
shape.paths[i].set({
fill: 'red',
stroke: 'green',
strokeWidth: 5
});
}
}
object = shape;
canvas.add(shape);
canvas.renderAll();
});
var switchColors = true;
document.getElementsByTagName("button")[0].addEventListener('click', function() {
if (object.paths) {
for (var i = 0; i < object.paths.length; i++) {
object.paths[i].set({
fill: (switchColors ? 'green' : 'red'),
stroke: (switchColors ? 'red' : 'green'),
strokeWidth: (switchColors ? 10 : 5)
});
}
}
switchColors = !switchColors;
canvas.renderAll();
});
