If you want to implement camera functionality in your app, you can achieve it using the Native camera plugin.
.ts
//take Photo
takePhoto(sourceType:number) {
const options: CameraOptions = {
quality: 50,
destinationType: this.camera.DestinationType.DATA_URL,
encodingType: this.camera.EncodingType.JPEG,
mediaType: this.camera.MediaType.PICTURE,
correctOrientation: true,
sourceType:sourceType,
}
this.camera.getPicture(options).then((imageData) => {
let base64Image = 'data:image/jpeg;base64,' + imageData;
}, (err) => {
// Handle error
});
}
Tip: Simply call the above method with either of these parameters:
this.takePhoto(0);//to select from photo librarythis.takePhoto(1);//to capture using the camera0 corresponds to photo library, while 1 corresponds to Camera
User Interface Example:
After considering the most popular answer, here are some brief code snippets.
Let's define two types of options:
private cameraOptions: CameraOptions = {
quality: 100,
targetWidth: 600,
sourceType: this.camera.PictureSourceType.CAMERA,
destinationType: this.camera.DestinationType.DATA_URL,
encodingType: this.camera.EncodingType.JPEG,
mediaType: this.camera.MediaType.PICTURE
}
private galleryOptions: CameraOptions = {
quality: 100,
sourceType: this.camera.PictureSourceType.PHOTOLIBRARY,
destinationType: this.camera.DestinationType.DATA_URL,
encodingType: this.camera.EncodingType.JPEG,
mediaType: this.camera.MediaType.PICTURE
}
When calling the getPicture method from the camera,
make sure to replace the options object based on the specific scenario.
For using the camera,
this.camera.getPicture(this.cameraOptions).then((imageData) => {
let base64Image = 'data:image/jpeg;base64,' + imageData;
}, (err) => {
// Handle error
console.log(err)
})
For accessing the gallery,
this.camera.getPicture(this.galleryOptions).then((imageData) => {
let base64Image = 'data:image/jpeg;base64,' + imageData;
}, (err) => {
// Handle error
console.log(err)
})
Here is a possible solution:
InitializeCamera() {
const cameraSettings: CameraOptions = {
quality: 100,
destinationType: this.camera.DestinationType.DATA_URL,
encodingType: this.camera.EncodingType.JPEG,
mediaType: this.camera.MediaType.PICTURE
}
this.camera.getPicture(cameraSettings).then((imageData) => {
this.base64Image = 'data:image/jpeg;base64,' + imageData;
this.imageList.push(this.base64Image);
this.imageList.reverse();
}, (err) => {
console.log(err);
});
}
To utilize the image picker plugin, follow these steps:
fetchImage(){
let settings = {
maximumImagesCount:1 // Set the desired number of images to pick (default is 15)
}
this.imagePicker.getImages(settings).then((selections) => {
for (var i = 0; i < selections.length; i++) {
console.log('Selected Image URI: ' + selections[i]);
}
}, (error) => {
console.log("An error occurred: "+error);
});
}
