How to customize image size in vue clip

With the increasing popularity of web applications, Vue, as one of the popular frameworks, is also widely used in various large and medium-sized projects. In the process of developing such applications, we will inevitably involve some processing operations involving images. This article will introduce how to customize image size in Vue clipping.

Vue editing is a convenient and easy-to-use front-end editing tool. Users can complete common image processing operations such as cropping, rotation, scaling, and filters on the web page. In actual application, we will find that some default settings are not suitable for our project needs, such as the default size of the selected image. At this time, we can customize the width and height of the image through the Vue component props.

First, in the template tag in the .vue file, we can add custom attributes to the img tag. For example:

<template>
  <div>
    <img :src="imgUrl" :width="imgWidth" :height="imgHeight"/>
  </div>
</template>

Among them, the :src attribute determines the source path of the image, :width and :height determine the width and height of the image .

Next, add imgWidth and imgHeight props to the component in the script tag to receive the passed custom parameters:

export default {
  name: "customImg",
  props: {
    imgUrl: {
      type: String,
      required: true
    },
    imgWidth: {
      type: Number,
      default: 400
    },
    imgHeight: {
      type: Number,
      default: 300
    }
  }
}

Here, imgWidth and imgHeight are declared as Number types respectively. , with default values ​​of 400 and 300 specified. Developers can modify it as needed. Here, we can also see that imgUrl is declared as String type and set as required.

Finally, reference the component in the Vue instance and pass custom parameters to props:

<template>
  <div>
    <custom-img :img-url="imageUrl" :img-width="500" :img-height="400"/>
  </div>
</template>

<script>
import customImg from "@/components/CustomImg";

export default {
  name: "App",
  components: {
    customImg
  },
  data() {
    return {
      imageUrl: "https://example.com/images/example.jpg"
    }
  }
}
</script>

Here, we introduce the custom-img component into the App and use: v-bind The directive passes values ​​to img-width and img-height. Among them, imageUrl is the image source path variable declared in data.

On this basis, we can continue to encapsulate components to achieve more customized functions. For example, add zoom ratio, adjust quality and other functions. These are based on Vue's writing method and component mechanism, and can be carefully customized according to project needs.

In short, customizing the image size in Vue editing is convenient and flexible. Simply modify the component parameters to adjust various image sizes.
