What does the picture aspect ratio of 6:7 mean?

The aspect ratio of the picture is 6:7, which means that the aspect ratio of the picture is 6:7. This means that if you know the width of the picture, you can calculate the height of the picture through the proportional relationship. Similarly, if you know the height of the picture, you can also calculate the width of the picture.

This proportional relationship is usually used in image processing and photography to ensure that the aspect ratio of the image is consistent and avoid deformation or distortion. When making or editing an image, it is necessary to observe the specified aspect ratio to ensure that the output image quality meets the requirements.
