Using latest Phantomjs binaries v1.9.7 on Azure websites, it renders black boxes instead of character.
here is an example of simple phantomjs script on Azure:
var page = require("webpage").create();
page.content = "Hello 123";
page.render("index.png");
phantom.exit(0);
the png and pdf result is [] [] [] [] [] [] [] in black
And the jpg result is big black box
This prevent us from using phantomJS as a webjob and within websites
Note : phantomjs is working fine on VM,WebRole and WorkerRole
