Description Valdas 2016-02-09 19:56:36 UTC

Using version 15.08.3

See attached photo "original.jpg". It is in portrait position.
If I load it in to GW, rotate it counter clockwise, save, close and open it again then it appears  rotated by 180 degrees (file "rotated_ccw.jpg"). And if I rotate clockwise then result is as no rotation is applied (file "rotated_cw.jpg").

Reproducible: Always

photo rotated CW

Comment 4 Valdas 2016-12-25 20:20:23 UTC

 Attaching another example:
 - original photo "pic_original.jpg";
 - original photo rotated one time 90 degrees CCW and saved to file named "pic_rotated_90_ccw.jpg".
 - original photo rotated two times 90 degrees CCW and saved to file named "pic_rotated_180_ccw.jpg".
 - original photo rotated three times 90 degrees CCW and saved to  file named "pic_rotated_270_ccw.jpg".
 As you can see results are not as expected.
