[英]How to take screenshot of googlemap from web page using PhantomJs?
我的要求是拍攝網頁Google Map的屏幕快照。我正在Google Map上動態繪制Markers和Polyline。我使用PhantomJS進行屏幕截圖。但是屏幕快照不是捕獲顯示在網頁上的完整Google Map 。
Html and javascript for loading and display google map
----------
<script>
function initMap() {
var mapOptions = {
zoom: 15,
center: new google.maps.LatLng(28.5354383, 77.26393259999998)
};
var map = new google.maps.Map(document.getElementById('map'), mapOptions);
var project_id = $('#project').data('url')
var latt = substation[0]
var lngg = substation[1]
var marker = new google.maps.Marker({
position: new google.maps.LatLng(latt, lngg),
title: new google.maps.LatLng(latt, lngg).toUrlValue(6),
map: map,
draggable: true,
label: {
color: 'black',
fontWeight: 'bold',
text: "Sub-Station",
},
icon: {
labelOrigin: new google.maps.Point(4, 25),
url: '/assets/sub_station.png',
}
});
google.maps.event.addListener(marker, "dragend", function(event) {
$.getScript("/update_pole.js?project_id=" + project_id + "&Type=SS" + "&new_cordinated=" + event.latLng.toString().slice(1, -1), function(data) {});
});
var lattt = feeder[0]
var lnggg = feeder[1]
var marker = new google.maps.Marker({
position: new google.maps.LatLng(lattt, lnggg),
title: new google.maps.LatLng(lattt, lnggg).toUrlValue(6),
map: map,
draggable: true,
label: {
color: 'black',
fontWeight: 'bold',
text: "Feeder",
},
icon: {
labelOrigin: new google.maps.Point(4, 25),
url: '/assets/ptw.png',
}
});
var page = require('webpage').create(); page.open('https://medhajtest.herokuapp.com/admin/visibilities/demo?id=586b524712598e0004f440d0', function() { page.viewportSize = { width: 1440, height: 900 }; var clipRect = page.evaluate(function(){ return document.querySelector("div#map").getBoundingClientRect(); }); page.render('github.png'); phantom.exit(); });
請注意屏幕截圖的尺寸為400x300。 這是默認的PhantomJS視口大小。 打開頁面之前,必須設置所需的視口大小。
var page = require('webpage').create();
// Got to set this before opening a page
page.viewportSize = { width: 1440, height: 900 };
page.open('https://medhajtest.herokuapp.com/admin/visibilities/demo?id=586b524712598e0004f440d0', function() {
var clipRect = page.evaluate(function(){
return document.querySelector("div#map").getBoundingClientRect();
});
page.render('github.png');
phantom.exit();
});
