FLIP OR ROTATE





This button opens a dialog box with buttons for choosing object rotations by 

90, 180, and -90 degrees.  Additional choices are flipping about the 

horizontal or vertical axis.  The final choice is to transpose the image.

Both the 'Original' and the 'Processed' images are rotated.  In addition, 

if the x- and y-dimensions are not equal, and the rotation exchanges axes, 

then the dimensions are exchanged.





The 'Arbitrary Rotation' function allows selection of the rotation 

angle specified in degrees, radians, or pi-radians (e.g. entering 2 would 

rotate the image by 2*pi radians or 360 degrees).  Enter number as an 

integer or floating-point number.  Both the 'Original' and 'Processed' images 

are rotated.  A source pixels are moved to nearest-neighbor destination 

pixels.  If the image is non-square, it is truncated to the largest, 

centered, included image.
