我需要您的帮助来在使用 ABCpdf 渲染 pdf 时显示图表。
这是结果，浏览器中的内容和 pdf 中的内容:
实际上，由于它在 html 上看起来不错，我认为问题出在渲染 pdf 上。这是我用来创建 pdf 的代码:
var theDoc = new Doc();
theDoc.HtmlOptions.Timeout = 10000;
theDoc.HtmlOptions.UseScript = true;
theDoc.HtmlOptions.PageCacheEnabled = false;
theDoc.HtmlOptions.OnLoadScript = "(function(){ " +
"window.ABCpdf_go = false; " +
"onLoad(); " +
"window.ABCpdf_go = true; })();";
theDoc.AddImageUrl("file:///E:/development/temp/test(1).html");
theDoc.Save(string.Format("output-{0}.pdf", DateTime.Now.Ticks));
theDoc.Clear();
这是我的 html 页面:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
function drawChart() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows([
['Mushrooms', 3],
['Onions', 1],
['Olives', 1],
['Zucchini', 1],
['Pepperoni', 2]
]);
var options = {
'title': 'How Much Pizza I Ate Last Night',
'width': 400,
'height': 300
};
var chart = new google.visualization.PieChart(document.getElementById('chart-div'));
google.visualization.events.addListener(chart, 'ready', function () { onChartRenderReady(chart);});
chart.draw(data, options);
}
function addText(text) {
var h = document.createElement('h1');
var t = document.createTextNode(text);
h.appendChild(t);
document.body.appendChild(h);
}
function onDOMContentLoaded() {
addText('From onDOMContentLoaded event');
drawChart();
}
function onLoad() {
addText('From onLoad event');
drawChart();
addText('Finished drawing chart');
}
function onChartRenderReady(chart) {
addText('From onChartRenderReady event');
var imageDiv = document.getElementById('chart-image');
imageDiv.innerHTML = '<img src="' + chart.getImageURI() + '">';
addText('Added image');
// ABCpdf_RenderComplete();
}
function test() {
addText('test');
}
function ABCpdf_RenderWait_Dummy() {
addText('ABCpdf_RenderWait_Dummy');
}
function ABCpdf_RenderComplete_Dummy() {
addText('ABCpdf_RenderComplete_Dummy');
}
google.load('visualization', '1.0', { 'packages': ['corechart'] });
document.addEventListener("DOMContentLoaded", onDOMContentLoaded);
window.onload = onLoad;
</script>
<style>
#chart {
height: 300px;
width: 400px;
border: 1px solid black;
}
</style>
</head>
<body>
<div id="chart-image"></div>
<form id="chart">
<div id="chart-div"></div>
</form>
<h3>Static text (should be always present)</h3>
</body>
</html>
很高兴获得任何帮助。

该问题仅出现在 Gecko Engine 中。添加 theDoc.HtmlOptions.Engine = EngineType.Gecko; 后问题得到解决
