Multiple File Modes  
You can open files four ways in Stereoviewer. You can open a single image file (into both eyes) as a: stereo pair or as single image. (See below for examples.) For added flexibility, you can load a separate image into the left eye, and you can load another image into the right eye. To speed things up, you can load the left and right eyes in succession with one command.
Loading as a stereo pair...
 
The left half of the file is loaded into the left eye. The right half is loaded into the right eye.
 
Loading as a single image...
 
The single image is loaded into both the left and right eyes.
Alter Red/Cyan  
on red/cyan = The left eye image only contains the Red color component, while the right eye contains the Cyan color components (Green and Blue). on cyan/red = The left eye image contains the Cyan color components (Green and Blue), while the right eye only contains the Red color component. off = reloads the images in both eyes with all RGB color components (not pictured)

Full Screen  
On = The image fills the entire screen for both eyes. Off = Returns the image to its original window size. (Please note: Maximizing the window still includes the title bar.)
Position Image  
"Top up" rotates the image as opened originally. "Top left" rotates image 90 degrees counterclockwise. "Top down" rotates the image upside down. "Top right" rotates the image 90 degrees clockwise. (This image is opened with the top facing up.)

Top up

Top left

Top down

Top right
Please note: This positioning is relative to the orientation of the image when opened. For instance, if you open an image which is facing sideways (say its top is facing west) and you select "Top left," the image will rotate 90 degrees counterclockwise so its top faces the bottom.
Reset Image Settings  
image separation to 0 = resets the separation back to zero. all viewing defaults = resets viewing options back to default settings
Stereoviewer allows the user to align the images to achieve the desired 3D effect. With the arrow keys, the user can shift the right eye image one pixel at a time in four directions.  
Use the arrow keys to align the images:
 
¬(left arrow) repositions the right eye image one pixel to the left
 
®(right arrow) repositions the right eye image one pixel to the right
 
­(up arrow) repositions the right eye image one pixel upward
¯(down arrow) repositions the right eye image one pixel downward
Multiple Display Sizes  
"Keep aspect ratio in window" retains the image proportions within the current window size. "Fit to left/right window" stretches or shrinks the image to fit the current window size. "Fit both to left window" fixes the right eye image to the window size of the left eye (to assist in aligning the two images). "Fit both to left image" adjusts the size of the right image to match the size of the right image. "Same as file size" loads the image into the eyes as its original file dimensions. See examples below.
Keep aspect ratio in window...
 
     
Fit to left/right window...
 
     
Fit both to left window...
 
     
Fit both to left image...
 
     
Same as file size...
 
Set Stereo Buffer  
on = writes the image(s) to all quad buffers First pair: The Red/Cyan => on red/cyan feature is on. The status "stereo buffer" can be seen in the title bar of the display window. off = writes the image(s) to double buffers Second pair: Here the user can see the anaglyph created from the two overlapping images. On red/cyan is still active and the right eye has been shifted with the arrow keys to obtain a 3D effect. (Here the shift is exaggerated for illustrative purposes.)
left eye

                                                                                       right eye
Save Display to File  
left display = saves the image in the left display window to a PNG file.  right display = saves the image in the right display window to a PNG file
Here is the image above trimmed and saved as "test.png." A "Save As" dialog box pops up to prompt for a filename and location to save the file.
Trim image overlap  
When trim is applied to the image as shown above, the red border formed by the image in the left eye is removed and the remaining portion where the images overlap remains.
Please note: Make sure you like the image size as viewed in the current window. When you apply the trim feature, the resulting image is captured within its current window size.  If you maximize the image after a trim, you will see the pixels.
