How to implement picture-in-picture and multiple exposure of pictures in Vue?

Introduction:
In modern web design, the display effect of pictures is a very important link. Picture-in-picture and multiple exposure are two common photo manipulation effects that can make pictures more vivid, unique and attractive. This article will introduce how to use the Vue framework to achieve these two effects and provide relevant code examples.

1. Implementation of picture-in-picture effect
Picture-in-picture is an effect in which a small-sized picture is nested in another large-sized picture. The key to achieving the picture-in-picture effect is to use the positioning and cascading functions of CSS. Below is a simple Vue component example to show how to achieve a picture-in-picture effect.

In the above code, we create a container namedpicture-in-picture, which contains a background image and a foreground image. In order to achieve the picture-in-picture effect, we use CSS to position the foreground image in the upper left corner of the background image and set its size. In this way, the foreground image will be displayed inside the background image, thereby achieving a picture-in-picture effect.

2. Implementation of Multiple Exposure Effect
Multiple exposure is an effect that overlaps two or more pictures together, thereby creating a blended and transparent effect. The way to achieve a multiple exposure effect is to use CSS blending modes. Below is an example of using Vue to achieve a multiple exposure effect.

In the above code, we create a container namedmultiple-exposure, which contains a background image and an overlay image. By setting themix-blend-modeproperty of CSS tooverlay, we can mix the overlay image with the background image. In this way, the color and brightness of the overlay image interact with the background image to achieve a multiple exposure effect.

Conclusion:
Through the Vue framework, we can easily achieve picture-in-picture and multiple exposure effects of pictures. Just use CSS features such as positioning, cascading, and blending modes to create unique and vivid image display effects. The above sample code can be used as a reference to help you achieve these two effects in your Vue project.
