OS X’sPreview is the little image viewer that keeps on giving. Preview is so feature-richthat there’s usually little reason to install another image viewer. It can even resize a large batch of images at once.

OS X的Preview是不斷提供的小型影象檢視器。 預覽功能如此豐富,以至於通常沒有理由安裝另一個影象檢視器。 它甚至可以一次調整大量影象的大小。

Resizing in batches makes short work of what would normally be a tedious and time-consuming process, assuming you’re resizing all your images to the same dimensions.

假定您將所有影象調整為相同的尺寸,則批量調整大小可以簡化通常很繁瑣且耗時的過程。

To perform a batch resize, you can either open Preview from the Dock and File > Open your images…

要執行批量調整大小,您可以從Dock中開啟預覽,然後選擇檔案>開啟影象…

…or, you can select a bunch of images in the Finder, right-click on them, and then choose Open With > Preview.

…或者,您可以在Finder中選擇一堆影象,右鍵單擊它們,然後選擇“開啟方式”>“預覽”。

All of your images should open in Preview’s left sidebar.

您所有的影象都應在“預覽”的左側欄中開啟。

Now, you could gothrough each image, click on the “Tools” menu, and select “Image Size” to resize them one by one. But wehave a better way. First, select all the images by clicking on the “Edit” menu and then “Select All”, or using the keyboard combination Command+A.

現在,您可以瀏覽每張影象,單擊“工具”選單,然後選擇“影象大小”以逐一調整它們的大小。 但是我們有更好的方法。 首先,通過單擊“編輯”選單,然後單擊“全選”,或使用組合鍵Command + A選擇所有影象。

Now you will see that all your images are highlighted, which means they’re selected.

現在,您將看到所有影象都突出顯示,這意味著它們已被選中。

Now, click on the “Tools” menu and select “Adjust Size…”.

現在,單擊“工具”選單,然後選擇“調整大小…”。

Since our images are varying sizes, the width and height values will tell us they have “Multiple Values” but we know that our width needs to be 325 pixels for all of them. So, we enter this number and then click “OK”.

由於我們的圖片大小各不相同,因此寬度和高度值會告訴我們它們具有“多個值”,但我們知道所有圖片的寬度都必須為325畫素。 因此,我們輸入此數字,然後單擊“確定”。

We’re not done, however. In order to make these values stick, we need to save our images. Again, we don’t have to save each one separately. Since all our images are selected, we can go ahead and click on the “File” menu and choose “Save”, or use the keyboard shortcut Command+S.

但是,我們還沒有完成。 為了使這些值保持不變,我們需要儲存影象。 同樣,我們不必分別儲存每個。 由於已選擇所有影象,因此我們可以繼續並單擊“檔案”選單,然後選擇“儲存”,或使用鍵盤快捷鍵Command + S。

Once saved, you will notice that the “Edited” notation in the titlebar will disappear.

儲存後,您會注意到標題欄中的“已編輯”符號將消失。

You can use this trick with any other changes you make to multiple images in Preview, so you can rotate, adjust the color, and more. But for us, resizing is bar none the most useful option for our purposes. Undoubtedly this will be a big time saver for many folks who use a Mac and the Preview app.

您可以將此技巧與對“預覽”中的多個影象所做的任何其他更改一起使用,以便旋轉,調整顏色等。 但是對於我們來說,調整大小絕不是實現我們目的的最有用的選擇。 無疑,對於許多使用Mac和Preview應用程式的人來說,這將節省大量時間。
