(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) dividerĭraws a full-width, one line-tall graphical divider.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. it2dlĭownloads a file, but does not display it inline. imgcatĭisplays one or more images inline at their full size. Provides an augmented directory listing that includes a thumbnail of each image in a directory. Sample code for displaying images may be found here. This is a security measure to prevent a download gone wrong from using unbounded memory. If the file's size exceeds the declared size, the transfer may be canceled. A new menu item titled Downloads will be added to the menu bar after a download begins, where progress can be monitored and the file can be located, opened, or removed. Any image format that macOS supports will display inline, including PDF, PICT, EPS, or any number of bitmap data formats (PNG, GIF, etc.). Any kind of file may be downloaded, but only images will display inline. auto: The image's inherent size will be used to determine an appropriate dimension.īy omitting the inline argument (or setting its value to 0), files will be downloaded and saved in the Downloads folder instead of being displayed inline. ![]()
