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.
