![]() ![]() The manpage for fbi has a full description of the command line arguments and is fairly straightforward to read. Slideshows can be shown using fbi -a -t 5 *.jpg where 5 is the number of seconds the image will show for. Then, images can be shown full screen using the command fbi -a myimage.jpg. Making a GIF Now that you know how to take multiple photos, let’s see how you can turn that sequence into an animated GIF. This is done using the package management system commands sudo apt-get update sudo apt-get -y install fbi. To use fbi to show images in the console, first it needs to be installed. However, a tool called fbi (short for framebuffer imageviewer) can show images in framebuffer mode. ![]() Unfortunately, display from imagemagick doesn't appear to do this. For other formats, it will try to use ImageMagicks convert. In this case, you can display images directly using an application that understands the framebuffer. By default, it displays bmp, gif, jpeg, PhotoCD, png, ppm, tiff, and xwd from the Terminal itself. If the text isn't massive, you're probably running in framebuffer mode. Further features are display of EXIF tags, JPEG comments, EXIF rotation/orientation, load of description files, faster load via image caching, command. ![]() There are however some exceptions! Generally a Raspberry Pi connected directly to a monitor users a framebuffer console, which is a high-resolution psuedo-graphics console. Generally to display images in Linux you need the GUI (graphical user interface) to be running, which you've discovered how to start with the startx command. 1.The Raspberry Pi can request and get information from other software applications online through an API (Application Programming Interface). ![]()
