"Category": "位圖圖像圖形格式",
"Pros": "壓縮損耗保持在最低限度。任何壓縮比都不會影響圖像質量。該格式非常適合存儲圖像的中間版本。重新保存圖像時，圖像的質量不會丟失。PNG 支持大量的顏色。它允許多層次的透明度。使用圖層的能力。能夠添加到文件元數據。文件的大小很小。",
"Cons": "不適合使用全綵色照片。無法將多個圖像保存在一個文件中。不允許動畫。",

"BasicInformation": "以便攜式網絡圖形 (PNG) 格式保存的圖像文件稱為 PNG 文件。它包含一個無損壓縮位圖，與 .GIF 文件的位圖相媲美。Web 圖形、數字圖片和具有半透明背景的圖像通常保存為 PNG 文件。最初，PNG 圖像格式旨在替換 GIF 圖像格式，因為它們都支持透明背景。索引顏色和無損壓縮的使用是兩者之間的另一個相似之處。另一方面，PNG 文件不受同樣的版權限制。",
"DetailedInformation": "覆蓋在方格背景上的是一個帶有 8 位透明圖層（頂部）（底部）的 PNG 圖像。PNG 採用通縮，這是一種非專利的無損數據壓縮技術。在大多數情況下，PNG 可以比 GIF 更有效地壓縮圖像，但一些實現使用不適當的過濾方法，導致不必要的巨大 PNG 文件。PNG 格式的透明度有三種類型：一種用於索引圖像、彩色圖像，另外兩種用於灰度或真彩色圖像。伽瑪值、背景顏色和文本內容都是可以在 PNG 文件中記錄的所有圖像屬性。該標準允許每個通道最多 16 位，但是，大多數客户每個通道只需要 8 位。為了保存圖像，PNG 格式被廣泛使用，特別是在互聯網上。它可以處理索引（基於調色板）的 24 位 RGB 或 32 位 RGBA（帶有第四個 Alpha 通道的 RGB）彩色圖像。格式支持全綵色、非索引 RGB 或 RGBA 照片以及灰度圖像。不同的計算機用户可能會遇到 PNG 文件，無論他們是從網站下載圖像、接收附在電子郵件中的數字照片，還是截圖。對於 Web 使用，圖形設計師經常將圖形另存為 PNG 文件。他們還使用 PNG 文件來保存半透明的徽標或圖標模型，可以疊加到其他圖片上。",
