nativescript-dynamsoft-camera-enhancer

Nativescript 插件用于 Dynamsoft Camera Enhancer。

我们可以用它进行相机预览，这是构建条形码扫描仪、文本扫描仪、文档扫描仪等的基础。

安装

npm install nativescript-dynamsoft-camera-enhancer

用法

在布局中添加相机视图

<Page xmlns="http://schemas.nativescript.org/tns.xsd" 
    xmlns:dce="nativescript-dynamsoft-camera-enhancer"
    navigatingTo="navigatingTo" class="page">
    <GridLayout rows="*, auto, auto">
        <dce:CameraEnhancer 
        loaded="{{ dceLoaded }}" 
        rowSpan="3" 
        active="{{ isActive }}"
        cameraID="{{ desiredCamera }}"
        torch="{{ desiredTorchStatus }}"></dce:CameraEnhancer>
    </GridLayout>
</Page>

在代码后获取相机增强实例

dce:CameraEnhancer;
dceLoaded(args: EventData) {
  this.dce = <CameraEnhancer>args.object;
}

方法

captureFrame(): any;
captureFrameAsBase64(): string;
getAllCameras(): string[];
getSelectedCamera(): string;
getCameraEnhancer(): any;
getResolution(): Resolution;
setResolution(resolution:Resolution): void;
setZoom(factor:number);
getMaxZoomFactor(): number;
open(): void;
close(): void;

属性
