Attribute Description

Image Rotation
|
(0070,0042)
|
1
|
How far to rotate the image clockwise in degrees, before any Image Horizontal Flip (0070,0041) is applied.
Enumerated Values:
-
0
-
-
90
-
-
180
-
-
270
-
Note
Negative values are not permitted since the Value Representation is unsigned.
|
|
Image Horizontal Flip
|
(0070,0041)
|
1
|
Whether or not to flip the image horizontally after any Image Rotation has been applied such that the left side of the image becomes the right side.
Enumerated Values:
-
Y
-
yes
-
N
-
no
Note
No vertical flip is specified since the same result can be achieved by a combination of a 180 degree rotation and a horizontal flip.

Note
Given the definition of the Grayscale Transformation Sequence in PS3.4, it is apparent that the rotation, flipping and magnification will be applied AFTER the application of any bit-mapped overlays or graphic annotations that are specified in the image pixel spaces, but BEFORE the application of graphic annotations that apply in the Specified Displayed Area relative space.
