動畫是未來幾年內(nèi)行動的來源,至少,如果不是無限期的。這一切當(dāng)然導(dǎo)致猜想,聲稱Flash動畫是真正的標(biāo)準(zhǔn),正式被認(rèn)可或不被接受。另一個限制是寶貴的幾個圖形包裹還不能支持SVG,除了Adobe Illustrator9和Photoshop 6。一是SVG,盡管人們接受為一種法定的標(biāo)準(zhǔn),還需要一個插件在你的瀏覽器中顯示。XML支持在動態(tài)矢量圖形或動畫時可以連接各種數(shù)據(jù),從而可能從根本上改變網(wǎng)頁內(nèi)容的發(fā)送。SVG支持視覺濾鏡效果應(yīng)用在真正的時間而不是成為框架,并包括音頻。再者,它是用平底鍋和縮放功能。背后的理念是提供網(wǎng)上SVG與矢量圖形的標(biāo)準(zhǔn),以同樣的方式,GIF和PNG是位圖,JPG標(biāo)準(zhǔn)。在大家都在談?wù)摰臒衢T技術(shù)中,目前能勝過動畫,在將來的某個時候可擴展的是矢量圖形,或者SVG。你雇傭他們創(chuàng)造一個30秒的電影代表了你自己,而不是創(chuàng)建自己的使用標(biāo)準(zhǔn)的軟件包。對所有意圖和目的,一個CyberSpot序列看起來有點像一個基本的動畫影片與音頻,但在加載時在頃刻之間沒有任何的開場白。這些存在,但他們對方法這樣的做法比動畫更有所有權(quán),而且通常被他們的創(chuàng)造者極端謹(jǐn)慎地用閃光的專利保護(hù)著。如果不是,你則會被限制到更多的傳統(tǒng)動畫的任務(wù)中。還是要選擇一詞,編程。然而,不像閃電,沖擊波插件是一個漫長的下載,并需要有些煩瑣的安裝過程,其中包括在一個時間點上退出你的網(wǎng)頁瀏覽器。沖擊波仍然還很健康的活著,并且在許多情況下藏在Flash的后面,在視覺上的互動性和質(zhì)量上顯示。雖然Flash是有趣的,但這并不是一個完整的多媒體環(huán)境。第二個缺點可能你不關(guān)心,但這是Flash不是實際上標(biāo)準(zhǔn)的同樣方式,作為HTML,GIF,JPG,PNG或類似的形式。首先,它要求你的聽眾安裝一個插件的動畫播放器。也許最好的一切,從一個有經(jīng)驗的設(shè)計師的角度來看,電影可以設(shè)定為盡快開始無需等待下載程序的完成。更好的是,還是Flash動畫可合并事件和反應(yīng)用戶的輸入,使它適應(yīng)接口,開發(fā)定制的網(wǎng)頁的HTML不希望去模仿。在每一個實際測試中,從簡單的翻轉(zhuǎn)式和按鈕來完成序列的影響,你就會發(fā)現(xiàn)Flash文件都小于動態(tài)gif和Java行動的負(fù)載速度。閃光方法的優(yōu)點是很可觀的,而且隨著時間的推移越來越更引人注目。當(dāng)萬維網(wǎng)聯(lián)盟霸占了20世紀(jì)90年代的大部分動畫技術(shù)。最大的缺點是它沒有任何的有趣之處,結(jié)果它變得俗不可耐。令人高興的是,關(guān)于這種方法的動畫,因為它在開始和運動時是幾乎是散的,不被框架的。近來,設(shè)計師們已經(jīng)能夠產(chǎn)生基本路徑運動為靜態(tài)圖像使用DHTML。他們可以達(dá)到相當(dāng)?shù)拇笮?如果他們包括10多幀左右,因為壓縮基于在每一個圖像的數(shù)字不同的顏色。動畫gif的局限性是眾所周知的,但讓我們總結(jié)他們吧。GIF動畫一直是的主要的橫幅和簡單的,影響至今。,這意味著他的瀏覽器總是硬盤攪動,下半截是通常散布在空格為接下來的每幀載入。通過發(fā)送的幀序列持續(xù)的基礎(chǔ)上,一種基本的動畫效果是不可能的。早在1994年,斯梅金,男孩在商業(yè)網(wǎng)站開發(fā)想出了一個極其基本的形式,發(fā)送連續(xù)動畫GIF圖像到瀏覽器。謝天謝地,當(dāng)涉及到圖形動畫,你仍然有一個的選擇的范圍。這是什么意思,至少直到大屏幕和高速互聯(lián)網(wǎng)連接成為一種標(biāo)準(zhǔn),你已經(jīng)無法對視頻做什么。對網(wǎng)頁設(shè)計所做的一切就是裁員。讓我們面對它,網(wǎng)絡(luò)是令人失望的。然而,最新品種的軟件已建成能夠捕捉設(shè)計者的想象力,而沒有消耗掉腦力。s claim that Flash is the real Web animation standard, officially recognised or not. With a widening range of design products now capable of exporting to Flash, including Illustrator and FreeHand, not to mention LiveMotion, Flash is where the action39。t expect the audience to locate and install thirdparty plugins. These exist, but they do so with solutions that are even more proprietary than Flash, and usually protected by their creators with ridiculously extreme caution. One example of an alternative to Flash that doesn39。 if not, you39。re happy about scripting, indeed if you have some JavaScript experience, you39。s even a lively market for cartoons and games using Shockwave and its offline player ShockMachine. Unlike Flash, however, the Shockwave plugin is a long download and requires a somewhat fiddly installation process which includes exiting your Web browser at one point. The big limitation of both Flash and Shockwave from a graphic artist39。re talking about hundreds of millions of people, ready to go with your animation content. Fun and sexy though Flash is, it39。t matter that Flash isn39。s that Flash isn39。s point of view, the movies can be set to start running as soon as the download mences without waiting for it to plete. There are two principal drawbacks to the Flash format. First, it requires your audience to have a plugin Flash player installed. However, to Macromedia39。ll find that Flash files are smaller than animated GIFs and load up faster than Java actions. Vectors also mean that the movies can resize themselves automatically to fit the browser screen, antialiasing on the fly. Better still, Flash movies can incorporate events and react to user input, making it terrific for developing custom Web page interfaces which HTML couldn39。s not really animation. While the World Wide Web Consortium squandered most of the 1990s considering some proper animation technologies, Macromedia just went for it. The result was Flash, a system of playing back selfcontained movies containing vectorbased graphics and text within a Web page or independently running in a Web browser. The advantages of the Flash approach are considerable, and getting more pelling as time goes on. In the first instance, the vector nature of Flash movies allows you to include quite plex graphics and sequences in the confidence that they39。s summarise them anyway. GIFs are bitmap images, so e at a fixed size regardless of browser window size. They can reach quite exciting sizes if they include more than 10 frames or so, because pression is based on the number of different colours in each image. They also tend to appear in a jerky fashion during the download, leaving the user staring at a seemingly inexplicable sequence running at one frame every five seconds the first time round. More recently, designers have been able to produce basic path motion for static images using DHTML. Instead of running an animation in one fixed place, DHTML techniques let you take a single image and move it around over the top of your page as an independent, floating object. The nice thing about this approach is that the animation, for what it is, starts almost immediately and the movement is perfectly smooth, not being framebased. The graphic can also have a transparent background just like any GIF. The big drawback is that it doesn39。s take a look at the main techniques, and their drawbacks, for getting your site animated today. Back in 1994, the backroom boys in mercial Web development came up with an extremely basic form of animation by sending consecutive GIF images live to the browser. Advertisers had been using this method to change ad banners every 30 seconds or so without waiting for the user to refresh the page. By sending a sequence of frames on a constant basis, an elementary animation effect was possible. The drawback, of course, was that graphic data was constantly being downloaded over the line after the page itself had loaded. On a modem, this meant the browser was always flickering and the hard disk churning, and frames were usually interspersed with blanks as each subsequent frame loaded. Soon after, the animated GIF was born, effectively packing the GIF frame seq
