Store image taken from external camera and store it in DB - Ionic 3












1















I'm creating an application using ionic 3. The app is supposed to do the following: take an image from external camera (it will return it as file URL), store it in local DB using sqllite as base64.



This is my attempt



takeImage(){
const fileTransfer: FileTransferObject = this.transfer.create();

this.takePicture().subscribe(data => {
this.wait(7000);
this.listFiles().subscribe(data => {
const url = data['results'].entries[0].fileUrl;
fileTransfer.download(url, this.file.dataDirectory + data['results'].entries[0].name).then((entry) => {
this.room.img = entry.toURL();
this.base64.encodeFile( entry.toURL()).then((base64File: string) => {
this.room.img = base64File;},
(err) => {
console.log(err);
});
}, (error) => {});
},
err => {console.log(err);});
},
err => {console.log(err);});
}


I have tried to display the base64File but it is not working.

          To display a base64 image you need to import DomSanitizer in component and create the instance variable in the constructor below is the code



          constructor(public _DomSanitizer: DomSanitizer)

          <img class="one-image" *ngFor="let image of item; let i= index" style="height:120px;" [src]="_DomSanitizer.bypassSecurityTrustUrl(image.imgUrl)" #images (click)="imageOption(i,images,image.data,image.ext)"/>

          • I don't think the problem lies in displaying the image. I have tried images from the gallery and shows correctly. Could it the conversion to base64 file is not correct?I'm not sure.

            are you getting proper image url in entry.toUrl() and did you check image is downloded in local files ? . One more question why you are passing two values in this.room.img is image got displayed from entry.toUrl() ?
