![]() ![]() There are better tools such as viu or timg for cross-protocol terminal image viewing, please go and give them love. Kitty, Sixel, and Iterm2 protocols are not supported, It uses almost exclusively ANSI escape codes to display Viuwa is a simple terminal ANSI image viewer trying to maintain bare-minimum compatibility with the wasm32-wasi target. TERMINAL IMAGE VIEWER DOWNLOADNB tmpfs has to hold 2 photos = the 'current display' and the 'next to display' (if you just over-write the current photo, the display goes all 'corrupted' as fbi tries to show a partially written jpg file ).# 91 in Command line utilities Download history 41/week 49/week 61/week So, instead, the script can copy the new photo to a "tmpfs" folder (so the actual photo is in RAM disk) before changing the 'master' alias. The problem is, this will hammer your photo source as fbi will actually fetch the photo 3 times a second = and as the 'source' bottlenecks, fbi will crash. If you want 'instant' swap, then you set fbi cycle time = 1 second (so it's running at 3 photo's per sec) so it will 'change over' within 1/3rd sec. There will be a delay whilst fbi 'fetches' the new photo. ![]() TERMINAL IMAGE VIEWER WINDOWSjpg's on USB (stick) or WiFi or Ethernet (eg Windows 'shared' folder) sh script runing in the background and 'looking' for. You can guess what comes next = when you want to show a new photo, all you have to do is change the 'master' alias to 'point' at the new photo ! This can be done by a simple. 1 or 2 won't work (fbi will 'cache' them even though you set cache 0 = only 3+ will force it to actulaly fetch the files) With 'cache = 0', 3 is the minimium to get fbi to actually fetch each of the 3 photos in turn (which, of course, are all aliased to the same 'master' so it ends up showing the exact same photo 'all the time'). You then launch fbi to 'cycle for ever' (rather than 'display once and stop'). symbolic links) to the same 'master' photo. You set up fbi to cycle through 3 'dummy' photos, all 'pointing' (using alias command 'ln -s' i.e. Yes, I know this is an old 'tread'', however it seems people do still use fbi so I thought I would 'post' my PhotoFrame 'final solution'. If (waitpid(pidProcess, &iReturn, WNOHANG) = pidProcess) NB don't be tempted to COPY new.jpg to d.jpg (fbi will show 'corrupted' data on screen as the file it's in the process of loading is overwritten by the cp)Ĭode: Select all pid_t pidOldJPGDisplay, pidNewJPGDisplay (the -t sets it to run 'for ever' on a 3 second cycle over the 3 images - so changing d.jpg should result in the new image appearing within 1s) fbi -d /dec/fb0 -a -noverbose -t 3 -cahcemem 0 d.jpg a1.jpg a2.jpg fbi has to be started with (at least) 3 images, since even with -chachemem 0, fbi will 'cache' 2 images (and thus never load the 'change')Įg. (so my slide show will 'pause' as the 'display a new image' (background task) checks for a button push before changing the alias to a new image) When you want to 'display a new image', make d.img an alias of the new image (ln -s -f new.jpg d.jpg) Make a1.jpg and a2.jpg both 'alias' of d.jpg (ln -s -f d.jpg a1.jpg, ln -s -f d.jpg a1.jpg) I set fbi to 'loop for ever' showing 3 'static' image names, d.jpg, a1.jpg, a2.jpg (see note at end) My requirement was to 'pause' a fbi slideshow, keeping the current image on display before moving seamlessly to the next = I expect my 'cunning trick' with soft links (alias) will help you. You can 'loop' it on a single image, and then 'killall fbi' (to force a clean up) just fine - and then re-launch for the next image - however, when you 'kill' it, the current image is removed from the screen and the screen reverts to whatever (typically, the status text from the log-in) ![]() If you set it to show a single image, fine - but it fails to clear up correctly (it has a RAM leak ?) so if you invoke it multiple times to show many images in succession and after 50 or so and the Pi crashes with insufficient RAM (it doesn't support stdin, so you can't 'pipe' it images to display) Fbi won't 'quit' cleanly (or at all) = It won't run in the background, so if you set it to 'loop' through a dir it will show all the images (that exist when it is launched = it does not recheck the dir contents later) just fine but that user log-in is then locked to fbi. ![]()
