This program allows to view "MPO" files as well as stereoscopic JPGs on monitors that suport 3D, e.g. LG monitors with polarized glasses.

Supported JPG are two seperate files of full size (must have ".v1." and ".v2." in the filename), and single JPGs with half-size side by side pictures. Those are created by 3dpic for example:

The Fuji Finepix 3D camera creates stereoscopic 3D fotos saved as MPO.

Description at amazon

They are saved as ".MPO" files, which are basically 2 jpegs merged after each other.

They could be extracted with "mposplit" from http://cstein.kings.cam.ac.uk/~chris/mposplit/

You then could use my converter "3dpic" to create a side by side jpeg of those two single jpegs.

You then could watch them in 3D with a standard 2D picture viewer on a 3D-monitor.

So why an own utility like mpoview?

1.) it automates the above steps (it uses mposplit itself, a binary is included in the pet).

2.) It uses an own window to display the resulting side-by-side image, allowing manipulations.

You have a "parallax control" on the X-axis as well on the Y-axis.

So if your fotos have "ghosting" as they are not well aligned (this even happens with an expensive solution like the finepix), you now may correct the view on the monitor.

The Finepix also has an inbuilt parallax control, and allows to save the corrected view.
mpoview has an additional Y control, and it is easier to adjust the view on a huge monitor than on the small inbuilt display of the camera.

I wrote the viewer in Genie, and compiled it in fluppy 013.

If the binary will not work, you had to install vala and compile it like this:

Hmm... wonder if that'd work with the pictures my Nintendo 3DS takes. Reportedly, it also takes MPO format pictures, though some have said it's not exactly the same. I haven't bothered to take the SD card out of the 3DS and grab a photo to test (not that I've taken any interesting pictures with it, anyway Mr. Green

).

Makoto,just tried it with a mpo file from http://kurifuri.com/2011/07/04/3d-photos-for-the-nintendo-3ds.

But mposplit cannot handle it, it gives the errror:

Added a link to the windows version in the first message.
It includes the GPL and the required Gtk libraries (Download: 4 MB).

After installation you can drop a mpo file from the explorer on the mpoview desktopicon to view it.

Updated mpoview.pet in the first message (not the windows-version).

Changes:
- save button.
It saves the current view (so actually your parallax correction) to /tmp/mpoview/save/

3 files are created, like
001.v1.jpg (left)
001.v2.jpg (right)
001.v4.jpg (left/right halfwidth)

Files of the same name are overwritten without request.

You also can show the next/previous image in the current folder with left/rightclick on an image.
