I'm looking for (Linux-based) software that can view (and perhaps catalogue), in real time, images like webcams, graphs, NASA imagery, weather radar, etc. Some are dirt simple, like "this file on disk is updated now and then, so refresh from disk". Some are a little trickier, like URLs where every access gives you a fresh image, so I have to decide the refresh frequency myself. Others have a single URL, but the latest image is only updated at certain times. If an image is updated every five minutes on the fives, I'd want to access it at (for example) 9:05:30, 9:10:30, etc. If I get the same picture (slow update), maybe retry at 9:06:30, 9:07:30, etc. Others have a URL based on the time (and also have the "new image every n minutes" characteristic, above). So I'd want to access image_200604120905.png, say. Currently, I have Perl scripts that use the same core but are hardcoded and custom tailored to each set of images. I've got solar graphs and ultraviolet/magnetic imagery, local weather radar and weather satellite imagery, network layout and status graphs, etc., all of which use "feh" as their full-screen X11 display program. (Some like my network status graph are as simple as running "feh" with the "refresh" option set, since they're just local files.) If such a program doesn't exist -- and now that I detail all my specs, I'm much more doubtful that it does -- I guess I'll just have to make something myself, or live with my current scripts. But I figured maybe I'd luck out here. :) Failing that, I'd also love to find a full-screen X11 viewer that I can somehow control externally, e.g. "change to this picture", from a program -- sort of like a picture version of XMMS (which has APIs for external control). That way, whatever I write can skip the whole GUI aspect. Obviously, it's a little hard to Google, so I'm hoping someone has experience with a similar program. And having said that, I'm sure that if it does exist, Murphy's Law says it'll turn out I was just using the wrong keywords and I'll look like a goof. ;) (BTW, hope this isn't off-topic for the "linux" list, since I'm discussing Linux-based software. If it is, let me know so we don't spam the wrong list.)
