Firefox 3 0 the first to experience the web page zoom function elements
Firefox 3 0 the first to experience the web page zoom function elements
Firefox 3.0 the first to experience : the web page elements zoom function can be zooming throughout all the elements of the website, including pictures and text, after Opera and IE 7 had already introduced a feature.
Back in 1999 Mozilla has made the whole concept of scalability pages, but limited in Firefox 2.0 is the Gecko1.8 engine, this feature does not join the Firefox browser to. The Mozilla Firefox 3.0 will use a new Gecko 1.9 engine, Gecko 1.9 graphics architecture has made fundamental changes, Gecko 1.8 using the traditional gfx graphics architecture, it is a software program, from the CPU to complete the 2D graphics image exaggerate; Gecko 1.9 and revert to the "Cairo" graphics architecture, "Cairo" can take advantage of the GPU to be responsible for rendering 2D graphics and video, to achieve the equivalent of page-rendering GPU hardware acceleration, so that the CPU has been completely liberated. Because the current GPU generally have very strong hardware performance, commitment page-rendering tasks will be very relaxed and therefore theoretically, Gecko 1.9 engine can achieve faster rendering speed, and it can significantly reduce the CPU resources occupancy rate, the real significance of the leap. Firefox 3.0 result in the introduction of full page zoom function is also easily realized.
The latest version of Firefox nightly Although we have had the whole page zooming function, but since the relevant user interface and feature buttons had not come out, so we do not see this feature. However, a foreign player can be found using Firefox built-in JavaScript error console to call this function.
Open Javascript console enter the following code? Evaluate button, pages will be enlarged to three times the current size, the final numerical changes can be achieved on different rates of scaling. Firefox 3.0 believe in the official release, this function will be more people to join the family firefox one of the reasons.
