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. |

| 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.) |

| 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. |
