Android Question Rotate Photo Orientation S3

You shouldn't use numbers for the orientation. There are constants in this library that you should use instead: http://www.b4x.com/android/help/jpegutils.html#exifdata_orientation_rotate_90

i dont understand this @Erel , how to know when i need rotate or no the photo on s3?

i m using this
exif.Initialize(fp, "tiradacamera.jpg")
exif.setAttribute(exif.TAG_ORIENTATION, exif.ORIENTATION_ROTATE_90)

later the photo is taked but this dont rotate the photo , and i cant rotate this via code, bacause the user can take photos on landscape too

Why are you setting the orientation attribute? It will not rotate the image.

this is the problem
Msgbox(exif.getAttribute(exif.TAG_ORIENTATION),"teste")
this is = 6 on galaxy s3 and another galaxy (samsung devices)

i can take photos in horizontal or vertical and the result is 6 ever only 6
how i can rotate the image if i dont know the correct current rotation?

look this image



i have take a picture in vertical, i get rotated photo
the Msgbox(exif.getAttribute(exif.TAG_ORIENTATION),"teste") of this photo is = 6

if i take on horizontal i get another rotation etc.

i m crazy man, how to make this correct?

can u show a sample pls how to take photos, if have not correct orientation set the correct?

i m really dont understand this bug on s3 device


for example, i made now if Msgbox(exif.getAttribute(exif.TAG_ORIENTATION),"teste") = 6 then rotate 90° and this works, but if i take a photo on horizontal (landscape) i get rotated photo again ¬¬

The constants values are:


You can ignore the exif values and explicitly set them yourself.

@Erel, can u test this sample i made pls?
you have a galaxy s3? with this sample u go have the rotated photos and the msgbox with the orientation correct.
can u help me using this sample? is camex example with changes.

thx

i m making a video to explain the problem

here @Erel i made a video using the s3

this is the problem =(

The video doesn't work here. I don't have a galaxy s3.

the video is normal now can u see pls? i made this video only to show what i dont know to explain

I was able to see the video with Chrome. See post #79 (and the posts before it): http://www.b4x.com/android/forum/th...ibrary-functionality.23801/page-4#post-151355

yes this is a good solution, but have a way to know when i take a photo with phone on horizontal(landscape)?
but note: i m not using #SupportedOrientations: landscape, i m using portrait, my app is portrait.
i need only a camera to take photos and give me corretect rotation. have a way to know when i take photos on horizontal and dont need change my app to #SupportedOrientations: landscape?

You can use PhoneSensors to monitor the device orientation.
