Displaying a FILE_URI image taken by Native Camera in Ionic 3 - ionic-framework

Question

How do you display a FILE_URI image taken by the user using #ionic-native/camera in Ionic 3?
I can use Ionic Native's Camera to get a FILE_URI image URL, with a result like this:
file:///var/mobile/Containers/Data/Application/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX/tmp/cdv_photo_005.jpg
However, When I try to display this image back to the user by referring to the URI in my view template, the image never loads.
Things I've tried:
-Using the image URI directly in the view
<img src="{{profile.image}}"> // Never loads
-Sanitizing the URI by including DomSanitizer in the page component:
<img [src]="domSanitizer.bypassSecurityTrustUrl(profile.image)"> // Never loads
I would rather not use a base64 image because of the performance drag. What am I doing wrong here?

Answer 1

import { normalizeURL } from 'ionic-angular'; ionic3 <img> tag src
<img *ngIf="base64Image" src="{{base64Image}}"/>
openCamera(pictureSourceType: any) {
let options: CameraOptions = {
quality: 95,
destinationType: this.camera.DestinationType.FILE_URI,
sourceType: pictureSourceType,
encodingType: this.camera.EncodingType.PNG,
targetWidth: 400,
targetHeight: 400,
saveToPhotoAlbum: true,
correctOrientation: true
};
this.camera.getPicture(options).then(imageData => {
if (this.platform.is('ios')) {
this.base64Image = normalizeURL(imageData);
// Alternatively if the problem only occurs in ios and normalizeURL
// doesn't work for you then you can also use:
// this.base64Image= imageData.replace(/^file:\/\//, '');
}
else {
this.base64Image= "data:image/jpeg;base64," + imageData;
}
}, error => {
console.log('ERROR -> ' + JSON.stringify(error));
});
}

Hi try to use File Path ionic plugin
path = "file:///var/mobile/Containers/Data/Application/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX/tmp/cdv_photo_005.jpg";
this.filePath.resolveNativePath(path)
.then(filePath => console.log(filePath))
.catch(err => console.log(err));
Please read the documentation

You can use the below code for display the image
savePhotoClick = () =>{
const options: CameraOptions = {
quality: 70,
destinationType: this.camera.DestinationType.DATA_URL,
encodingType: this.camera.EncodingType.JPEG,
mediaType: this.camera.MediaType.PICTURE
}
this.camera.getPicture(options).then((imageData) => {
// imageData is either a base64 encoded string or a file URI
// If it's base64 (DATA_URL):
this.base64Image = 'data:image/jpeg;base64,' + imageData;
}, (err) => {
// Handle error
});
Then use the img tag for display
<img [src]="base64Image" *ngIf="base64Image" />
