Image Rotation
Live and captured images displayed in the Nikon DXM 1200 ACT-1 control software image windows can be rotated and flipped by a menu found in the Live settings panel. This interactive tutorial explores the appearance and orientation of flipped images. Control of the applet features is identical to that found in the native Nikon software.
The image orientation can be configured in the Live settings panel to include a flipping function that is activated by the Flip checkbox in the Direction menu. Placing a check mark in the checkbox with the mouse cursor will enable image flipping by one of four re-orientation radio buttons. The default setting is image flipping turned Off with no change in orientation. This feature is conveniently utilized to flip the image at a specific angle in accordance with the manner in which the image appears through the microscope's eyepieces. Options available with the Flip menu include rotating the image 90 degrees in either a clockwise or counter clockwise direction and a complete 180 degree rotation. When this feature is activated, images appearing in the live image window are rotated or flipped to the orientation dictated by the radio button selection.
The actual displayed image orientation can become confusing due to slight inconsistencies between the flip nomenclature and the action taken by the software. When the Flip function is deactivated, the image appears in the live display exactly as it is seen through the microscope eyepieces. Upon activating the Flip checkbox with the default radio button selection set to "0" degrees of rotation, the image is actually flipped horizontally. All other rotations (90 and 180 degrees) are permutations of the original horizontal flip. Images that have been flipped by 90 degrees (either clockwise or counter clockwise) are resized by the software to fit into the window. This requires a minor reduction in the image size to allow the entire image to be placed within the confines of the window. When the Flip checkbox is deactivated, the radio buttons will continue to perform rotation functions, but will start without first flipping the image horizontally.
