GIF：圖形交換格式 (GIF: Graphics Interchange Format)

GIF is an abbreviation of Graphics Interchange Format. It is extensively used for animations and still images on the World Wide Web. The image is set out is bitmap image and it consists of a file extension .gif. In 1987, It was launched by CompuServe. The chief idea behind its development is to create an image format that is independent of the platform. Lempel-Ziv-Welch (LZW) lossless data compression method is used to compress GIF images. This method is used to diminish the size of the file without lowering the standard of the image.

GIF是Graphics Interchange Format的縮寫 。 它被廣泛用于萬維網上的動畫和靜止圖像。 該圖像是位圖圖像，由文件擴展名.gif組成。 1987年，它由CompuServe推出。 其開發背后的主要思想是創建獨立于平臺的圖像格式。 Lempel-Ziv-Welch(LZW)無損數據壓縮方法用于壓縮GIF圖像。 此方法用于減小文件的大小而不會降低圖像的標準。

The 8-bit format is used in GIF images which keep up with 256 colors. To make new colors, these 256 colors cannot be mixed. It is in-demand on the internet because of its small size and transportability and manageability specifications. It is contemplated prime for line art with a limited amount of colors, images with huge flat regions of color and images that require being high- spirited or animated.

8位格式用于保持256色的GIF圖像。 為了產生新的顏色，不能混合這256種顏色。 由于其體積小，可傳輸性和可管理性規格，它在Internet上很受歡迎。 對于有限數量的顏色的線條藝術，具有巨大的平坦顏色區域的圖像以及需要高昂的精神或生氣勃勃的圖像，可以考慮使用這種方法。

GIF版本 (Versions of GIF)

  1987年，第一個版本發布為GIF87a。

用法 (Usage)

• GIFs are appropriate with a limited amount of colors for sharp-edged line art such as a logo.

  GIF適用于顏色有限的顏色，用于徽標等銳利的線條藝術。

• LZW technique is used for data compression so there is no sign of agitation of data loss and it supports flat regions of constant color with effectively stated edges.

  LZW技術用于數據壓縮，因此不會出現數據丟失的跡象，它支持具有有效邊緣的恒定顏色的平坦區域。

• In small animations and low-resolution clips of film, it can be used.

  在小型動畫和低分辨率的影片剪輯中，可以使用它。

• In games, it can be used.

  在游戲中，可以使用它。

• To merge GIF files with website background colors, it favors transparent backgrounds to be used.

  要將GIF文件與網站背景顏色合并，它傾向于使用透明背景。

優點 (Advantages)

• As compared with other file formats, one of the prime benefits of using animated gifs is the size which can be comparatively smaller.

  與其他文件格式相比，使用動畫gif的主要好處之一是尺寸可以相對較小。

• It helps in giving a highly professional look to a specific website having animation over a diverse background.

  它可以顯示對于組織良好的圖像而言不可行的動作和情感。

缺點 (Disadvantages)

• Due to its limited color pattern, in comparison to other image files the animated images designed can sometimes look poorer.

  由于其有限的顏色模式，與其他圖像文件相比，設計的動畫圖像有時看起來更差。

• Once the animation has already been coded into the authentic gif file, it cannot be edited.

  一旦將動畫編碼為真實的gif文件，就無法對其進行編輯。

• It will end up showing a less prudent version of that file because the images will not load immediately when the connection lags a bit.

  最終將顯示該文件的較不謹慎的版本，因為當連接滯后一點時，圖像將不會立即加載。
