XnView Software

I'm a long time user, this is my viewer of choice for my images.
Didn't see this topic here, so here goes...

3dtv's are becoming more and more popular!

The first idea is an very easy fix; the fullscreen image mode needs a 'keep image ratio' option. Some 3dtv's like the image to fill the whole screen when viewing .JPS files in side by side mode (SBS-H, side by side half) or the images looked squashed. These JPS are basically a jpg with 2 photos side by side, left and right eye view.

The other idea below is more advanced and I can see if you'd not care to implement them.

The best example is the 3d section of youtube. http://www.youtube.com/watch?v=FSGfN9rr78Q (a video for example)
-click the gear icon.
-beside 3d click options
-now you see the 3d tv modes; interlaced (column/vertical, row/horizontal, checkered), side by side (half, full)

I am willing to test some of these on my 3dtv and give feedback if you wish to develop them. My tv does row interlaced and 3D SBS half.

Another idea is a full 3d SBS mode for the app, basically you full screen xnview, and display the same contents on each half of the screen. It's hard on the eyes to be in SBS mode viewing an image and exit out of an image to select another and see the rest of the app isn't doing SBS, as this gives you half the screen in one eye and the other half in the other eye.

I took a stab at creating a stereoscopic 3D SBS image viewer myself in autohotkey. Apparently there's more to it than stretched fullscreen without aspect ratio for some files.
The above method only works with landscape photos, which is what I wanted it for anyway, win! My program does the job quite nicely if anyone is interested, until xnview fully supports JPS files. Just drop a line.

portrait JPS files in SBS mode are a bit more tricky, they have to be centered on their half of the screen.

Original image with aspect ratio with regular viewer:
----x|x----
----x|x----
----x|x----

should be split and separated to work with stereoscopic 3D SBS:
--x--|--x--
--x--|--x--
--x--|--x--

Luckily, once the images are split, you can do other things easier, say:
-reverse the image positions on the screen easily (sometimes needs to be done as wrong images can go to wrong eyes depending on camera)
-zoom/pan in in 3D (as long as the zoom is done per screen half)
-rotating even, maybe, maybe not?
