說明 |
GIF隻限於8位調色板,總共256顏色。GIF格式因此非常適合保存有較少幾個顏色的圖形,例如簡單的圖表,形狀,標誌,漫畫式圖像等。GIF格式支持動畫,至今仍廣被用來提供圖像動畫效果。它使用的無損壓縮,同樣顏色的面積越大,效果也強。不過圖像太過詳細或有抖動的話就不管用了。 |
High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. It was developed by the Moving Picture Experts Group. |
