#### 安装教程
            1.在项目根目录下的build.gradle文件中，
             allprojects {
                repositories {
                    maven {
                              url 'https://s01.oss.sonatype.org/content/repositories/releases/'
                          }
                }
             }
            2.在entry模块的build.gradle文件中，
             dependencies {
                implementation('com.gitee.chinasoft_ohos:DrawView:1.0.0')
        

在sdk6，DevEco Studio 2.2 Beta1下项目可直接运行
如无法运行，删除项目.gradle,.idea,build,gradle,build.gradle文件，
并依据自己的版本创建新项目，将新项目的对应文件复制到根目录下

#### 使用说明
 将DrawView添加到布局中
```java
<com.byox.drawview.views.DrawView
        ohos:id="$+id:draw_view"
        ohos:width="match_parent"
        ohos:height="match_parent"
        ohos:bottom_margin="80vp"
        ohos:top_margin="60vp"
        app:dv_draw_alpha="255"
        app:dv_draw_anti_alias="true"
        app:dv_draw_color="$color:thumColor"
        app:dv_draw_corners="round"
        app:dv_draw_dither="true"
        app:dv_draw_enable_zoom="true"
        app:dv_draw_font_family="default_font"
        app:dv_draw_font_size="12"
        app:dv_draw_max_zoom_factor="8"
        app:dv_draw_mode="0"
        app:dv_draw_style="2"
        app:dv_draw_tool="0"
        app:dv_draw_width="4"
        app:dv_draw_zoomregion_maxscale="5"
        app:dv_draw_zoomregion_minscale="2"
        app:dv_draw_zoomregion_scale="4"
        app:dv_draw_is_camera="true"/>
```
在Java代码中, 可以设置/更改一些DrawView的属性.
```java
mDrawView.setDrawColor(newPaint.getColor().getValue())  //设置画布颜色
        .setPaintStyle(newPaint.getStyle())             //定义视图的绘制样式
        .setDrawWidth((int) newPaint.getStrokeWidth())  //设置画布宽度
        .setDrawAlpha(newPaint.getAlpha())              //绘制颜色的透明度
        .setAntiAlias(newPaint.isAntiAlias())           //使用抗锯齿值进行绘制
        .setLineCap(newPaint.getStrokeCap())            //设置画笔类型
        .setFontFamily(newPaint.getFont())              //用于绘制文本的字体系列
        .setFontSize(newPaint.getTextSize());           //设置字体大小
```
