如何在计算机上的 Illustrator 中调整图像大小

Many complicated edits have become prevalent, especially with the emergence of pro photo editing applications like Adobe Illustrator. But, it’s still possible to do simple editing with these powerful editing apps. For example, you can still use Adobe Photoshop if you want to resize the dimension of your image. And did you know? You can resize your image in Illustrator using two methods. One is by manually scaling your image, and the other is by typing numerical values that you prefer for your photo. And in this guidepost, we will show you these two methods on how to resize images on Illustrator.

第 1 部分。如何在 Illustrator 中调整图像大小

Adobe Illustrator 是专业人士最常用的照片编辑软件。此应用程序允许您使用其复杂的数字绘图工具创建出色的输出。它非常适合创建基于矢量的插图、图标、排版、徽标等。此外，它还具有高级颜色选项，可用于创建调色板、渐变配色方案以及混合不同颜色以实现惊人的图像输出。

您可以使用 Adobe Illustrator 做很多事情。上述功能只是 Illustrator 提供的众多功能中的一部分。如果您问 Adobe Illustrator 是否可以调整图像大小，那么答案是肯定的。继续阅读本部分以了解如何在 Illustrator 中调整图像大小的步骤。

如何使用图像缩放器在 Illustrator 中调整图像大小

Step 1. The primary thing you must do is to download Adobe Illustrator on your computer. After downloading and installing the app, run it on your device. Then, open your image in Illustrator by navigating File > Open. You can also copy and paste your image onto an artboard you have already opened.

Step 2. Then, click the Selection Tool (Cmd V on your keyboard) and click your image to select it. After selecting it, the handles will appear on the corners of your image. These handles look like tiny white squares with a blue outline. With these handles, you can scale/resize your image, rotate it, and shear it.

Step 3. To resize your image by scaling, hold and drag any of the handles to your preferred size. Also, you are allowed to lock the aspect ratio of your image by holding Shift on your keyboard and moving your cursor.

根据您的偏好调整图像大小后，您现在可以释放单击手柄。

如何使用 Adobe Illustrator 通过调整数值来调整图像大小

现在，我们将教您如何通过使用“变换”菜单输入数值来调整照片大小，而不是使用“选择工具”手动缩放图像。

Step 1. Once Adobe Illustrator is opened on your device, open the Transform menu by clicking Windows > Transform. You can also prompt this menu by hitting Shift + F8 on your keyboard. Here is what the Transform menu looks like.

The Transform menu allows you to change the location of your object concerning the X and Y axis. You can also use this menu to rotate, shear, and resize your image by inputting a numerical value.

Step 2. Then, select the image that you are resizing by using the Selection Tool. And then, adjust the width and height in the Transform menu by changing the numbers based on what size you like for your photo. The letter W indicates the width, and the H indicates the height of your image.

Step 3. It will also help if you lock the aspect ratio of your photo by clicking the Chain icon beside the height and width. When you select the Chain option and change the height of your image, the width will follow.

Tip. You can change the default unit of measurements of your image as well. Illustrator uses pixels (px) as the default unit measurement. You can change the unit by:

◆ 厘米 (cm)

◆ 毫米（mm）

◆ 英寸（英寸）

◆ 百分比（%）

To change the unit of measurement of your image, type them after the number of your measurement. Once you change the numerical value and the unit of your image, press Enter on your keyboard.

Now, we will export your image. Select your image using the Selection Tool, right-click it, and select Export Selection.

After selecting the Export Selection option, the Export for Screens menu will appear. This menu will enable you to save your resized image in a usable format.

Under the thumbnail, you can preview your output and change the name of your file to what you prefer. Then, on the Export to panel, click the folder icon to the browser for the location of your output. Also, make sure that your Scale field is set to 1x. And then, choose your output format. It is suggested that you use a PNG or JPG format.

And finally, click the Export Asset button to save your output.

很神奇，对吧？ Adobe Illustrator 可让您根据自己的喜好编辑图像。如果您搜索如何在 illustrator 中调整图像大小而不失真，这部分也是答案。但是，此应用程序不是一个用户友好的工具，因为它没有易于使用的界面。因此，如果您想使用易于使用的应用程序调整图像大小/放大图像，请仔细阅读下一部分。
