GIMP 教程：如何使用 GIMP 裁剪图像
GIMP
你可能想在 [GIMP](https://www.gimp.org/) 中裁剪图像的原因有很多。例如，你可能希望删除无用的边框或信息来改善图像，或者你可能希望最终图像的焦点是在一个特定细节上。


在本教程中，我将演示如何在 GIMP 中快速裁剪图像而又不影响精度。让我们一起来看看吧。


### 如何在 GIMP 中裁剪图像

#### 方法 1


裁剪只是一种将图像修整成比原始图像更小区域的操作。裁剪图像的过程很简单。


你可以通过“工具”面板访问“裁剪工具”，如下所示：

你还可以通过菜单访问裁剪工具：“<ruby> 工具 → 变形工具 → 裁剪 <rt>  Tools → Transform Tools → Crop </rt></ruby>”。


激活该工具后，你会注意到画布上的鼠标光标会发生变化，以表示正在使用“裁剪工具”。


现在，你可以在图像画布上的任意位置单击鼠标左键，并将鼠标拖到某个位置以创建裁剪边界。此时你不必担心精度，因为你可以在实际裁剪之前修改最终选区。

此时，将鼠标光标悬停在所选内容的四个角上会更改鼠标光标并高亮显示该区域。现在，你可以微调裁剪的选区。你可以单击并拖动任何边或角来移动部分选区。


选定完区域后，你只需按键盘上的回车键即可进行裁剪。


如果你想重新开始或者不裁剪，你可以按键盘上的 `Esc` 键。


#### 方法 2


裁剪图像的另一种方法是使用“矩形选择工具”进行选择：“<ruby> 工具 → 选择工具 → 选择矩形 <rt>  Tools → Selection Tools → Rectangle Select </rt></ruby>”。

然后，你可以使用与“裁剪工具”相同的方式高亮选区，并调整选区。选择好后，可以通过以下方式裁剪图像来适应选区：“<ruby> 图像 → 裁剪为选区 <rt>  Image → Crop to Selection </rt></ruby>”。

There are many reasons you may want to crop an image in [GIMP](https://www.gimp.org/?ref=itsfoss.com). You may want to remove useless borders or information to improve your image, or you may want the focus of the final image to be a specific detail for example.

In this tutorial, I will demonstrate how to cut out an image in GIMP quickly and without compromising the precision. Let’s see.

## Method 1: Use the crop tool in GIMP

Cropping is just an operation to trim the image down to a smaller region than the original one. The procedure to crop an image is straightforward.

You can get to the Crop Tool through the Tools palette like this:

![Use Crop Tool for cropping images in GIMP](https://itsfoss.com/content/images/wordpress/2020/06/Crop-tool.png)

You can also access the crop tool through the menus:

**Tools → Transform Tools → Crop**

Once the tool is activated, you’ll notice that your mouse cursor on the canvas will change to indicate the Crop Tool is being used.

Now you can Left-Click anywhere on your image canvas, and drag the mouse to a location to create the cropping boundaries. You don’t have to worry about the precision at this point, as you will be able to modify the final selection before actually cropping.

![Crop Selection](https://itsfoss.com/content/images/wordpress/2020/06/Crop-selection.jpg)

At this point hovering your mouse cursor over any of the four corners of the selection will change the mouse cursor, and highlight that region. This allows you to now fine-tune the selection for cropping. You can click and drag any side or corner to move that portion of the selection.

Once the region is good enough to be cropped, you can just press the “**Enter**” key on your keyboard to crop.

If at any time you’d like to start over or decide not to crop at all, you can press the “**Esc**” key on your keyboard.

## Method 2: Use rectangle select tool to crop images

Another way to crop an image is to make a selection first, using the **Rectangle Select Tool**.

**Tools → Selection Tools → Rectangle Select**

![Select 1](https://itsfoss.com/content/images/wordpress/2020/06/select-1.gif)

You can then highlight a selection the same way as the **Crop Tool**, and adjust the selection as well. Once you have a selection you like, you can crop the image to fit that selection through

**Image → Crop to Selection**

## Conclusion

Cropping precisely an image can be considered a fundamental asset for a GIMP user. You may choose which method fits better to your needs and explore its potential.
