縮放是描軟件中產生較大或較小圖像的處理程序

  掃描儀對原稿縮小或放大

  印畫冊縮放倍率縮放倍率是指掃描儀對原稿縮小或放大的倍率。縮放是描軟件中產生較大或較小圖像的處理程序，印畫冊使得捐描得到的圖像送人圖像編程序中時。

無需重新改變圖像大小在擔描軟件中。縮放比例與解析度成反比關系，印畫冊解析度越低，圖像的縮放比例越大當使用最大的解析度時。

縮放比例只能小於1例如用300的解析度掃描2hm×2hn的圖像。印畫冊在不描失細節而希望得到×4n的放大圖像時。

則應設定縮放比例為200%而保持解析度為這一結果與使用600的解析度100%的縮放比例掃描所得到的結果是一樣的。

但後者必須通過圖像編輯軟件將分辨更改為30M（文件大小維持不變）後再輸出在述例子中，印畫冊圖像的大小是通過調整縮放比例而不是用圖像編軟件改變的。
