Working in QML with camera

Mikeeeeee

Hi!
I can display the picture from the camera on the screen. But the picture does not rotate when you turn the phone. Please tell me how to turn it with the phone. Also trying to take a photo when I click on a single button and display this photo in the picture, but can't do it. Help please. Below is my code. qml

import QtQuick 2.12
import QtMultimedia 5.12
 
Camera1Form {
    buttonPhoto.onClicked: //photo
    {
        photoImage.source= camera
    }
}

ui.qml

import QtQuick 2.12
import QtQuick.Controls 2.12
import QtMultimedia 5.12
 
Item {
    width: 400
    height: 700
    property alias buttonPhoto: buttonPhoto
    property alias photoImage: photoImage
    property alias photoPreview: photoPreview
    property alias camera: camera
 
    Camera {
        id: camera
 
        imageProcessing.whiteBalanceMode: CameraImageProcessing.WhiteBalanceFlash
 
        exposure {
            exposureCompensation: -1.0
            exposureMode: Camera.ExposurePortrait
        }
 
        flash.mode: Camera.FlashRedEyeReduction
 
        imageCapture {
            onImageCaptured: {
                photoPreview.source = preview  // Show the preview in an Image
            }
        }
    }
 
    VideoOutput {
        anchors.bottomMargin: 300
        source: camera
        anchors.fill: parent
        focus : visible // to receive focus and capture key events when visible
    }
 
    Image {
        id: photoPreview
    }
 
    Image {
        id: photoImage
        x: 21
        y: 433
        width: 219
        height: 215
        fillMode: Image.PreserveAspectFit
        source: "qrc:/qtquickplugin/images/template_image.png"
 
    }
 
    Button {
        id: buttonPhoto
        x: 264
        y: 507
        text: qsTr("Photo")
    }
}

This too not work:

photoImage.source = photoPreview.source

Here I found a simple application .Help please on the basis of it to do function photography.

So I can save the picture. It remains to learn how to save it in the folder with the program, how to mirror the picture and how to rotate the camera with the tilt of the phone. Maybe you know how can something this be done?

    buttonPhoto.onClicked: //photo
    {
        camera.imageCapture.captureToLocation("C:/Users/New Owner/Pictures/IMG_00000001.jpg")
        var imageFile =camera.imageCapture.capturedImagePath
        console.log("test: " + imageFile)
    }

So the camera shows correctly when turning the phone. It remains to learn how to save images in a folder with the program and how to upload them to the pictures.

    VideoOutput {
        //anchors.bottomMargin: 300
        source: camera
        anchors.fill: parent
        focus : visible // to receive focus and capture key events when visible
        autoOrientation: true
    }

@Mikeeeeee
have you taken a look at the camera example?

https://doc.qt.io/qt-5/qtmultimedia-multimedia-declarative-camera-example.html

It has a capture feature.

I watched, but it is hard to understand this example. There are no comments in the code. And there is no ui.qml, so it is difficult to understand what is responsible for.
Connected a layer of C++ and then was able to save wherever I want.
But when I do this

photoImage.source = "file:C:/Users/New Owner/Pictures/IMG_00000001.jpg"*

The photo changes only once, the next time you take a photo in this file, the picture still does not change. Apparently the cache is stored at an old picture. How to upload a new image from an old file?

Mikeeeeee

QByteArray allows normally send image

QString AppCore::getImage(QString addressFile)
{
    QImage myImage(addressFile);

    QByteArray bArray;
    QBuffer buffer(&bArray);
    buffer.open(QIODevice::WriteOnly);
    myImage.save(&buffer, "JPEG");

    QString image("data:image/jpg;base64,");
    image.append(QString::fromLatin1(bArray.toBase64().data()));

    return image;
}
