powerpoint预览
If you can’t find the slide background that you’re looking for in PowerPoint’s presentation library, you can use any image of your own choosing. PowerPoint makes this possible in just a few simple steps. Here’s how.
如果您在PowerPoint的演示文稿库中找不到所需的幻灯片背景，则可以使用自己选择的任何图像。 PowerPoint仅需几个简单的步骤即可实现此目的。 这是如何做。
A word of caution before you begin. The image you select will be stretched to fit the slide size. If you use an image that’s too small, the image will be distorted when used as the background. Be sure to pick an image that works. High-resolution images work best.
在您开始之前请注意。 您选择的图像将被拉伸以适合幻灯片尺寸。 如果使用的图像太小，则用作背景时图像会变形。 请确保选择一个有效的图像。 高分辨率图像效果最佳。
When you’re ready, open the PowerPoint presentation that you would like to add a background image to. Once open, head over to the “Design” tab.
准备就绪后，打开要向其添加背景图像的PowerPoint演示文稿。 打开后，转到“设计”选项卡。
In the “Customize” group, select the “Format Background” button.
在“自定义”组中，选择“设置背景格式”按钮。
The “Format Background” pane will appear on the right-hand side of the window. Here, select “Picture Or Texture Fill” from the “Fill” group.
“格式化背景”窗格将出现在窗口的右侧。 在这里，从“填充”组中选择“图片或纹理填充”。
Once selected, more options will appear below. Under “Picture Source”, select the “Insert” button.
选择后，更多选项将显示在下方。 在“图片来源”下，选择“插入”按钮。
The “Insert Pictures” window will appear, presenting three different options for inserting an image.
将出现“插入图片”窗口，其中提供了三种不同的插入图像选项。
从文件 (From a File)
Selecting this option will bring up File Explorer (Finder for Mac). Here, navigate to the location of the image you’d like to insert, select it, and then click the “Insert” button.
选择此选项将打开文件资源管理器(适用于Mac的Finder)。 在这里，导航到您想要插入的图像的位置，选择它，然后单击“插入”按钮。
在线图片 (Online Pictures)
Selecting this option will bring up an online image search powered by Bing. Enter the type of image you’d like to locate in the search bar, or select a topic beneath the search bar to open a library of related images.
选择此选项将显示由Bing支持的在线图像搜索。 在搜索栏中输入您要查找的图像类型，或在搜索栏下方选择一个主题以打开相关图像库。
Whichever method you choose, locate and select the desired image and click “Insert”.
无论选择哪种方法，都可以找到并选择所需的图像，然后单击“插入”。
从图标 (From Icons)
Selecting this option will bring up the “Insert Icons” window, showing a large library of available icons. Select the icon you’d like to use as the background and click “Insert”.
选择此选项将打开“插入图标”窗口，其中显示了大量可用图标。 选择您要用作背景的图标，然后点击“插入”。
Regardless of which method you used to locate the image, once you’ve selected “Insert”, the image will appear in the background of your presentation.
无论您使用哪种方法定位图像，选择“插入”后，图像都会出现在演示文稿的背景中。
As you can see, the image we selected makes it pretty difficult to see the text in our slide. To fix this, adjust the “Transparency” slider until the image works well with the text. You can also fine-tune the percentage (by 1% increments) by clicking the up and down arrow to the right of the slider.
如您所见，我们选择的图像使我们很难看到幻灯片中的文字。 要解决此问题，请调整“透明度”滑块，直到图像与文本完美融合为止。 您也可以通过单击滑块右侧的向上和向下箭头来微调百分比(以1％为增量)。
The end result should leave your slide looking much better.
最终结果应该使您的幻灯片看起来更好。
Finally, it’s important to note that inserting the background image only takes place on the selected slide.
最后，需要注意的是，插入背景图像仅在所选幻灯片上进行。
If you’re wanting to reflect these changes to the entire slideshow, select the “Apply To All” option at the bottom of the “Format Background” pane.
如果您想将这些更改反映到整个幻灯片中，请选择“设置背景格式”窗格底部的“全部应用”选项。
Once selected, you’ll notice the background has been applied to all slides in the presentation.
选择之后，您会注意到背景已应用于演示文稿中的所有幻灯片。
