The background image shown in the image below cannot fill the entire page because the image is not wide enough.
If you want to fill the page, most of your friends will select the picture and drag it to the right to fill the page, but then you will find that the picture will be deformed.
For the overall beauty of PPT, today I will teach you a trick:
1. Select a picture and press Ctrl + C, Ctrl + V to copy a same picture.
2. Then click [Image Tools]-[Format]-[Size]-[Crop] button, drag the picture to the right to crop a small area and place it in the blank space.
If we do n’t flip horizontally here, after dragging, it will be widened and filled to the background, there will be a very obvious stitching mark.
3. Then select the cropped square, and click [Image Tools]-[Format]-[Arrange]-[Rotate]-[Flip Horizontal]. Finally, drag the square to adjust the width, so that the picture can fill the background and seamlessly link without deforming, which is very natural!
