Android摄像头图像的结果应该被捕获后旋转？ [英] Android camera resulted image should be rotated after the capture?
问题描述
我在写一个使用摄像头的Android应用程序。 我设置摄像头的显示方向以90，我的活动是一个纵向：
I'm writing an Android application that uses the camera. I'm setting camera display orientation to 90, my activity is in a portrait orientation:
camera.setDisplayOrientation(90);
我得到一个良好导向preVIEW的画面，但由此产生的图像旋转到-90度（逆时针）以及
I'm getting a well oriented preview picture, but the resulting image is rotated to -90 degrees (counter clockwise) and
exif.getAttribute(ExifInterface.TAG_ORIENTATION)
收益ORIENTATION_NORMAL
它是预期的行为？如果捕获之后我旋转造成影像？
returns ORIENTATION_NORMAL
Is it expected behavior? Should I rotate resulted image after the capture?

推荐答案
问题是相机的方向是一个完整的灾难（如拍摄图像），因为原始设备制造商不遵守标准。 HTC手机做事情的一种方式，三星手机做不同的方式，Nexus的线似乎坚持不管是哪个供应商，基于CM7 ROM中，我认为按照标准无论哪个硬件，但你的想法。那种你必须决定如何根据手机/ ROM上。见这里的讨论：<一href="http://stackoverflow.com/questions/3852154/android-camera-unexplainable-rotation-on-capture-for-some-devices-not-in-exif">Android对于某些设备上的相机拍摄无法解释的旋转（而不是在EXIF）
Problem is the camera orientation is a complete disaster (as is capturing an image) because OEMs do not adhere to the standard. HTC phones do things one way, Samsung phones do it a different way, the Nexus line seems to adhere no matter which vendor, CM7 based ROMs I think follow the standard no matter which hardware, but you get the idea. You sort of have to determine what to do based on the phone/ROM. See discussion here: Android camera unexplainable rotation on capture for some devices (not in EXIF)
