Fast jpeg viewer

[KKJensen]

Hi everyone,

I'm putting together a little gphoto2 based script (for shooting a camera tethered and viewing the image asap on the screen of the computer instead of on the camera) and it finishes with displaying a jpeg (or the most recently added jpeg in a directory).

What I'm trying to find is the fastest jpeg displaying program out there...the less gui the better since it will be run from a script. So far I'm playing with xzgv, mirage and feh. The default viewer in F13 seems to be miserably slow compared to any of these options. I'm sure there's others out there.

Also, if someone has any hints about how to how to do a bash script that will close the previous open (or make it go to the most recent addition to a directory) it would be greatly appreciated. The most functionality I'm really looking for is speed and maybe the ability to go to the previous/next image with the arrow keys.

cheers!

For pure speed, and for viewing one image at a time, it would probably be hard to beat the "display" command, which is part of the the "ImageMagick" package. By default, display presents the image full size. If the image is larger than fits on the monitor screen, a secondary small window is displayed allowing you to drag the image around.

You can also specify a size. So if your looking at pics that are larger than your monitor viewing area, you could, for instance,

display --resize 50% /path/to/your/picture.jpg

In a bash script, for killing the current running invocation of display, just put the result of "pidof display" into a variable, then "kill $yourpidvariable".

Thanks...I'll give display some attention and see how it goes. So far I'm leaning towards gqview since it reacts fast, can be fired up in full screen, pointed at one image and quickly flipped back to older images with the keyboard or mouse.

Now that I'm playing, I see my script killing the previous incidence of a viewer and then restarted a new one pointed at a different file makes the screen flickr a few times. I guess I'm going to start hunting for a way of keeping the same instance but somehow changing which image it's showing via a command in a terminal.

gwenview is also very fast
