android - how to automatically turn the picture in the right form (library cropper )? -


i use library cropper here in project. works cool, if photo made in portrait mode, flips , displayed in landscape mode.

here original photo - original opened program - program

there method in library cropimageview.rotateimage(90); can add button rererses picture when pressed. can make run once loaded in right mode?

imagecrop = (cropimageview) v.findviewbyid(r.id.imagecrop);         string picturepath = getarguments().getstring("image");         crudeimage = bitmapfactory.decodefile(picturepath);         imagecrop.setimagebitmap(crudeimage);

you need decode original image bitmap in orientation. detect image orientation using exifinterface, use matrix rotate bitmap image's original orientation:

crudeimage = bitmapfactory.decodefile(picturepath); float rotationdegrees = getrotationdegreestooriginal(picturepath); if (rotationdegrees != 0f) {     crudeimage = rotateimage(crudeimage, rotationdegrees); }  /**  * rotate bitmap given degrees  * @param bitmap    original bitmap  * @param degrees   rotation degrees  * @return  rotated bitmap  */ public static bitmap rotateimage(bitmap bitmap, float degrees) {     matrix matrix = new matrix();     matrix.postrotate(degrees);     return bitmap.createbitmap(bitmap, 0, 0, bitmap.getwidth(), bitmap.getheight(), matrix, true); }  /**  * rotation degrees need applied rotate image original orientation  * @param filename  full path image  * @return  rotation degrees, or 0 if file not found  */ public static float getrotationdegreestooriginal(string filename) {     final exifinterface exif;     try {         exif = new exifinterface(filename);     } catch (ioexception e) {         return 0f;     }      // detect original orientation rotate     int orientation = exif.getattributeint(exifinterface.tag_orientation,             exifinterface.orientation_normal);     switch (orientation) {         case exifinterface.orientation_rotate_180:             return 180f;         case exifinterface.orientation_rotate_90:             return 90f;         case exifinterface.orientation_rotate_270:             return 270f;         default:             return 0f;     } }
