I'm generating a sequence of images saved as .PNG files on disk, labelled say plot001.png, plot002.png, plot003.png. These are actually saved plots from Octave, a scientific data manipulation/plotting tool.

There are about 50-200 of these images.

I want to animate them on screen so I can see each frame displayed sequentially with my own specified pause between each frame (typically 200ms). I also want to be able to manually single step forwards and backwards in the sequence with a simple keypress.

I am not trying to create a video! I could use ffmpeg or something similar, but the resulting video would be compressed, hard to control frame by frame, and only 2 seconds long.

Several Windows image display tools like irfanview have a feature for this.. it allows you to play a slideshow with definable pause between the frames, and you can also just arrow left and right to manually control. This is perfect.

Is there a image preview tool for Linux that would give me this easy sequence viewing method? I'm running Ubuntu 9.10 if that matters.

Gwenview, which is available in Ubuntu 9.10, support that.

You can start a slideshow of any directory/images. Its default pause between images is 5 seconds, but you can configure it as you want. You can also step forward by pressing space or backward by pressing backspace.

This works pretty well. Surprisingly the slideshow timing is NOT configurable, but as a ad-hoc solution I can change my key repeat speed and hold down the space bar. Thanks! – BobBanana Dec 19 '09 at 2:14
    
@BobBanana When the slideshow is running, and you move your mouse at the top of the screen, a "toolbar" should appear. Click on "Configure full-screen mode" (the wrench icon). In the popup menu, the first thing should be a slider to adjust the timing. At least, in Gwenview 2.3.2 – Laurent Parenteau Dec 19 '09 at 3:52

From imagemagick:

animate -pause *.jpg

You can also use mplayer:

mplayer mf://*.jpg -mf fps=10
