iPad Camera Orientation in QuickReport Template

ChristopherEby2 — Wed, 27 Mar 2019 16:14:08 GMT

When I use the AppStudio Quick Report template on my iPad, try to attach an image from the camera, and switch from the back camera to the front camera, the camera video preview is rotated 180 degrees (is upside down). However, if I capture an image from the front camera, the preview shows it oriented correctly. I've tested my 6th Gen iPad (Model A1954) with both the QuickReport template for Appstudio versions 3.2 and 3.3 beta and am seeing this on both. The front camera rotation is correct in the Survey123 included in AppStudio 3.3. Is there a workaround for this?

We logged this as a bug (Case #02294905) but I found my own workaround. I pulled code from the latest Survey123 Template and added it to the code in the QuickReport Template to fix the issue. I made these changes to the CameraComponent.qml file:

1. First, I copied in a property to detect if the device is running iOS

readonly property bool isIOS: Qt.platform.os === "ios"

2. Then I copied in a function to detect

function isIPhone() {

if (Qt.platform.os === "ios" && AppFramework.systemInformation.hasOwnProperty("unixMachine")) {

if (AppFramework.systemInformation.unixMachine.match(/^iPhone/)) {

return true;

}

return false;

}

3. Finally, I modified the switchCamera() function to include the orientation logic from Survey123:

function switchCamera() {

if (QtMultimedia.availableCameras.length > 0) {

var cameraIndex = 0;

for (var i = 0; i < QtMultimedia.availableCameras.length; i++) {

if (QtMultimedia.availableCameras[i].deviceId === camera.deviceId) {

cameraIndex = i;

break;

}

cameraIndex = (cameraIndex + 1) % QtMultimedia.availableCameras.length;

if(QtMultimedia.availableCameras.length>1) isBackCamera = !isBackCamera

camera.stop();

camera.deviceId = QtMultimedia.availableCameras[cameraIndex].deviceId;

switch(cameraFlashMode){

case 0:

camera.flash.mode = Camera.FlashAuto;

flash_icon.source = "./assets/flash_auto.png"

break;

case 1:

camera.flash.mode = Camera.FlashOn;

flash_icon.source = "./assets/flash_on.png"

break;

case 2:

camera.flash.mode = Camera.FlashOff;

flash_icon.source = "./assets/flash_off.png"

break;

}

cameraCurrentZoomScale = 1.0

//Code pulled from Survey123 to fix iOS orrientation issue

if(iOS) {

videoOutPut.autoOrientation = false;

videoOutPut.orientation = Qt.binding(function(){

var currentOrientation = parseInt(Screen.orientation, 10);

if (camera.position === Camera.FrontFace) {

if (isIPhone()) {

return ((camera.orientation + 180) % 360) * -1;

}

else {

if (currentOrientation === 1 || currentOrientation === 0) {

return ((camera.orientation + 180) % 360) * -1;

} else if (currentOrientation === 2) {

return (((camera.orientation + 180) % 360) * -1) + 90;

} else if (currentOrientation === 4) {

return (camera.orientation + 180) % 360;

} else {

return (((camera.orientation + 180) % 360) * -1) - 90;

}

} else {

return camera.orientation;

}

});

}

//End of code pulled from Survey123 to fix iOS orrientation issue

camera.start();

}

This solved my issue!
