缩放

  本示例演示了通过参数配置开启全局缩放功能，包括开启底部菜单的缩放功能，开启/关闭缩放，初始化缩放比例以及最大、最小缩放比例。

  本示例基于教程快速指南开发，如果您不清楚怎样引入DDei设计器，请查看教程快速指南。

  如需了解详细的API以及参数说明，请参考API文档。

一、开启底部菜单的缩放功能

demo.vue

<script setup lang="ts">
import DDeiEditorView from "ddei-editor";
import { DDeiCoreStandLayout } from "ddei-editor";
import {DDeiCoreBottomMenuPanel} from "ddei-editor";

const options = {
  config: { 
    "grid": 0, //网格线
    "background": { color: "blue", opacity: 0.1 }, //背景色
    initData: {
      controls: [
        {
          model: "102010",
          text: "初始化图形"
        },
      ]
    }
  },
  //配置扩展插件
  extensions: [
    //布局的配置
    DDeiCoreStandLayout.configuration({
      //配置插件
      'top': [],
      'middle': ['ddei-core-panel-canvasview', 'ddei-core-panel-quickcolorview'],
      'bottom':[], 
      'left': [],
      'right': []
    }),
    //底部菜单栏的配置，只保留全局缩放相关按钮
    DDeiCoreBottomMenuPanel.configuration({
      'panels': ["ddei-core-panel-bottom-changeratio","ddei-core-panel-bottom-suitratio"]
    })
  ],
}
</script>

<template>
  <div style="width:400px;height:400px;margin:100px auto;">
    <DDeiEditorView :options="options" id="ddei_editor_1"></DDeiEditorView>
  </div>
</template>

二、开启/关闭全局缩放

demo.vue

<script setup lang="ts">
import DDeiEditorView from "ddei-editor";
import { DDeiCoreStandLayout } from "ddei-editor";
import {DDeiCoreBottomMenuPanel} from "ddei-editor";

const options = {
  config: { 
    GLOBAL_ALLOW_STAGE_RATIO:false, //关闭全局缩放
    initData: {
      controls: [
        {
          model: "102010",
          text: "初始化图形"
        },
      ]
    }
  },
  //配置扩展插件
  extensions: [
    //布局的配置
    DDeiCoreStandLayout.configuration({
      //配置插件
      'top': [],
      'middle': ['ddei-core-panel-canvasview', 'ddei-core-panel-quickcolorview'],
      'left': [],
      'right': []
    }),
    //底部菜单栏的配置，只保留全局缩放相关按钮
    DDeiCoreBottomMenuPanel.configuration({
      'panels': ["ddei-core-panel-bottom-changeratio","ddei-core-panel-bottom-suitratio"]
    })
  ],
}
</script>

<template>
  <div style="width:400px;height:400px;margin:100px auto;">
    <DDeiEditorView :options="options" id="ddei_editor_1"></DDeiEditorView>
  </div>
</template>

三、初始缩放比例

demo.vue

<script setup lang="ts">
import DDeiEditorView from "ddei-editor";
import { DDeiCoreStandLayout } from "ddei-editor";
import {DDeiCoreBottomMenuPanel} from "ddei-editor";

const options = {
  config: { 
    GLOBAL_ALLOW_STAGE_RATIO:true, //开启全局缩放(默认为开启)
    ratio:1.5, //默认缩放比例为150%
    initData: {
      controls: [
        {
          model: "102010",
          text: "初始化图形"
        },
      ]
    }
  },
  //配置扩展插件
  extensions: [
    //布局的配置
    DDeiCoreStandLayout.configuration({
      //配置插件
      'top': [],
      'middle': ['ddei-core-panel-canvasview', 'ddei-core-panel-quickcolorview'],
      'left': [],
      'right': []
    }),
    //底部菜单栏的配置，只保留全局缩放相关按钮
    DDeiCoreBottomMenuPanel.configuration({
      'panels': ["ddei-core-panel-bottom-changeratio","ddei-core-panel-bottom-suitratio"]
    })
  ],
}
</script>

<template>
  <DDeiEditorView :options="options" id="ddei_editor_1"></DDeiEditorView>
</template>

四、最大、最小缩放比例

demo.vue

<script setup lang="ts">
import DDeiEditorView from "ddei-editor";
import { DDeiCoreStandLayout } from "ddei-editor";
import {DDeiCoreBottomMenuPanel} from "ddei-editor";
import {DDeiCoreChangeRatioPanel} from "ddei-editor"; 


const options = {
  config: { 
    GLOBAL_ALLOW_STAGE_RATIO:true, //开启全局缩放(默认为开启)
    ratio:1.5, //默认缩放比例为150%
    initData: {
      controls: [
        {
          model: "102010",
          text: "初始化图形"
        },
      ]
    }
  },
  //配置扩展插件
  extensions: [
    //布局的配置
    DDeiCoreStandLayout.configuration({
      //配置插件
      'top': [],
      'middle': ['ddei-core-panel-canvasview', 'ddei-core-panel-quickcolorview'],
      'left': [],
      'right': []
    }),
    //底部菜单栏的配置，只保留全局缩放相关按钮 
    DDeiCoreBottomMenuPanel.configuration({
      'panels': ["ddei-core-panel-bottom-changeratio","ddei-core-panel-bottom-suitratio"]
    }),
    //配置缩放功能的最大、最小缩放比例，以及缩放步长
    DDeiCoreChangeRatioPanel.configuration({
      min:0.5,max:3.0,delta:0.1
    })
  ],
}
</script>

<template>
  <DDeiEditorView :options="options" id="ddei_editor_1"></DDeiEditorView>
</template>
