Save Image orientation

[jackeykabra]

Hello Siralam,

I have used your custom camera library it is working nice and perfect but my QA has found one issue. it does not issue from your side but I want to get this type of functionality in your library.

When we click native camera image in portrait mode you will be got perfect as the 90-degree image but
in your library, it perfectly works and reveals 90-degree.

but when we click native camera image in landscape mode you will be got perfect as the 90-degree image but in your library, it not reveals 90-degree it displays another degree image. I am giving screenshot what am I getting and what I want.

I think you will understand my point. I want to 90-degree capture pictures save in sd card from landscape or portrait mode.

I changed code in "CameraViewImpl.class", but no effect to "CameraActivity.java" files
like :
cameraView.setOnPictureTakenListener(new CameraViewImpl.OnPictureTakenListener() {
@OverRide
public void onPictureTaken(Bitmap bitmap, int rotationDegrees) {
startSavingPhoto(bitmap, rotationDegrees);
}
});

in this method every time I am getting rotationDegrees = -90 value.

I don't know I am wrong or right can you please help me with this solution.
Whatever mode we click image we save the 90-Degree image. Thank you in advance.

I am sorry but I am not sure about what you mean. Please clarify the below 2 questions:

(1) Does your activity fixed in portrait mode?
(2) if the answer to question 1 is yes, do you mean rotationDegrees are always -90 no matter how you hold your device?

[jackeykabra]

1. Yes, it's in portrait mode.
2. I hold landscape and portrait then taken picture. can you check mobile camera it gives same orientation. in this library, I attached screenshots as above of whatever angle from clicking image we will get image same orientation like 90.

[siralam]

I cannot reproduce this. And actually the device orientation is detected using sensors. If in case your device's sensor is broken / does not even have a sensor, the orientation will not work. May I know your device model?

[jackeykabra]

For example, I have taken a picture in landscape mode so image saved in that orientation means landscape. But I need that image in 90 degrees just like a taken picture in portrait mode.

[siralam]

I have taken a picture in landscape mode

That's why I asked the 1st question first. "Taken a picture in landscape mode" can mean "The activity is landscape" or "The device is held in landscape". Which one do you mean?

[jackeykabra]

Camera activity is in portrait mode but when we change our device orientation for click the photo in camera view then photo clicked in that orientation.

[siralam]

Hmmm.... I don't understand (in the sense of language) what do you mean by "for click the photo in camera view then photo clicked in that orientation"...

Is it possible for you to perform a screen recording?

[siralam]

Arrrrrrrrrrrr I finally got what you mean!!!!!

[siralam]

You mean, you want to take the photo when you hold your device in landscape,

So now the library will return a different orientation to you. So when you save the photo, the image has a longer width than height; but you still want to save the photo with shorter width than height, even if it does not look like what you see in the camera preview.

Am I correct?

(hmmm But this does not match what your screencap means)

[jackeykabra]

I am attaching one image. This image there are two images I have set at bottom of camera view the 1st image I have a click in the portrait mode it's perfect. A 2ed image I have click landscape and it's save in landscape. but now I want to save 2ed image same as the 1st image.

means whatever mode you have click but we save 1st ways to save our image.

[jackeykabra]

Are you understand my point?

Can you use your mobile default camera and take picture landscape and portrait then view in a gallery clicked images. Is it possible in this library? I have a check in Whatsup application it's work perfect.

[siralam]

So this is a perfectly normal use case...

Try to use debugger and add a breakpoint to onPictureTaken.
And then take a picture while holding the device in different orientations.

Can you observe the value of rotationDegrees changes by 90 degrees?

If not, please tell me your device model.

If yes, this means you haven't implement your code to rotate the image to the orientation you want before saving it.

[jackeykabra]

My device model is Moto g4 Plus.

I tried and debugger on onPictureTaken. I am get rotationDegrees value -90 every time form both orientations.

[siralam]

Hmm. Strange.

Do you have other device to try? I want to try to find out if it is the problem of the model only. I cannot reproduce this on all my devices.

And may you also post your related code, all from onPictureTaken called to saving the photo?
