आयनिक 3 उदाहरण के लिए
कॉर्डोवा और आयोनिक नेटिव प्लगइन्स इंस्टॉल करें:
$ ionic cordova plugin add cordova-plugin-camera
$ npm install --save @ionic-native/camera
आपके app.module.ts को कैमरा इंजेक्ट करने की आवश्यकता होगी:
import { Camera } from '@ionic-native/camera';
..........
@NgModule({
declarations: [
MyApp
],
imports: [
BrowserModule,
IonicModule.forRoot(MyApp),
...........
],
bootstrap: [IonicApp],
entryComponents: [
MyApp
],
providers: [
StatusBar,
SplashScreen,
Camera,
{provide: ErrorHandler, useClass: IonicErrorHandler},
..........
]
})
export class AppModule {}
कैमरा का उपयोग एक्शन शीट के साथ आसानी से Ionic 3 के साथ किया जा सकता है, आपका पेज नीचे दिए गए पेज की तरह होगा:
import { Camera, CameraOptions } from '@ionic-native/camera';
.........
export class YourPage {
private base64:any;
constructor(private camera: Camera,private actionsheetCtrl: ActionSheetController) { }
cameragalleryfun(){
let actionSheet = this.actionsheetCtrl.create({
title: 'Camera-Gallery',
cssClass: 'action-sheets-basic-page',
buttons: [
{
text: 'Camera',
icon: 'camera',
handler: () => {
//console.log('Camera');
const options: CameraOptions = {
quality: 60,
destinationType: this.camera.DestinationType.DATA_URL,
encodingType: this.camera.EncodingType.JPEG,
mediaType: this.camera.MediaType.PICTURE,
sourceType : this.camera.PictureSourceType.CAMERA,
targetWidth: 500,
saveToPhotoAlbum: false,
correctOrientation:true
}
this.camera.getPicture(options).then((imageData) => {
this.base64 = 'data:image/jpeg;base64,' + imageData;
}, (err) => {
// Handle error
});
}
},
{
text: 'Gallery',
icon: 'images',
handler: () => {
//console.log('Gallery');
const options: CameraOptions = {
quality: 60,
destinationType: this.camera.DestinationType.DATA_URL,
encodingType: this.camera.EncodingType.JPEG,
mediaType: this.camera.MediaType.PICTURE,
sourceType : this.camera.PictureSourceType.PHOTOLIBRARY,
targetWidth: 500,
saveToPhotoAlbum: false,
correctOrientation:true
}
this.camera.getPicture(options).then((imageData) => {
this.base64 = 'data:image/jpeg;base64,' + imageData;
}, (err) => {
// Handle error
});
}
},
{
text: 'Cancel',
role: 'cancel', // will always sort to be on the bottom
icon: 'close',
handler: () => {
//console.log('Cancel clicked');
}
}
]
});
actionSheet.present();
}
}
किसी भी ईवेंट से cameragalleryfun फ़ंक्शन को कॉल करें जैसे कि बटन पर क्लिक करें, यह छवि के लिए बेस 64 स्ट्रिंग लौटाएगा। अधिक विकल्प लागू किया जा सकता है। अतिरिक्त विकल्प के लिए देखें: https://github.com/apache/cordova-plugin-camera
