我正在使用PhantomJS将带有D3图表的html网页渲染为PDF报告。在对rasterize.js进行一些更改后,报告看起来非常完美。但是,无论我做出什么更改,都无法完全消除左右边距。是否有人能建议修改raterize.js以完全删除这些边距?我对文件所做的更改如下:
page.viewportSize = { width: 595, height: 842 }; //**A4**
if (system.args.length > 3 && system.args[2].substr(-4) === ".pdf") {
size = system.args[3].split('*');
page.paperSize = size.length === 2 ? { width: size[0], height: size[1], margin: '-150px' }
: { format: system.args[3], orientation: 'portrait', margin: '-4cm' }; //**Swapnil:- added a negative margin to utilize the entire width of the canvas. (Reduces the margins but does not eliminate them completely)**
} else if (system.args.length > 3 && system.args[3].substr(-2) === "px") {
size = system.args[3].split('*');
if (size.length === 2) {
pageWidth = parseInt(size[0], 10);
pageHeight = parseInt(size[1], 10);
page.viewportSize = { width: pageWidth, height: pageHeight };
page.clipRect = { top: 0, left: 0, width: pageWidth, height: pageHeight };
} else {
console.log("size:", system.args[3]);
pageWidth = parseInt(system.args[3], 10);
pageHeight = parseInt(pageWidth * 3/4, 10); // it's as good an assumption as any
console.log ("pageHeight:",pageHeight);
page.viewportSize = { width: pageWidth, height: pageHeight };
}
}
if (system.args.length > 4) {
page.zoomFactor = system.args[4];
}
page.open(address, function (status) {
if (status !== 'success') {
console.log('Unable to load the address!');
phantom.exit(1);
} else {
window.setTimeout(function () {
page.render(output);
phantom.exit();
}, 20000); // **Swapnil:- increased time out to ensure all the charts load perfectly**
}
});
谢谢!
