glslideshow(6) XScreenSaver manual glslideshow(6) NAME glslideshow - slideshow of images using smooth zooming and fades SYNOPSIS glslideshow [--display host:display.screen] [--visual visual] [--window] [--root] [--window-id number] [--duration seconds] [--transition seconds] [--pan seconds] [--fade seconds] [--letterbox | --clip] [--zoom percent] [--titles] [--delay usecs] [--fps] [--verbose] [--debug] [--wireframe] DESCRIPTION Displays a slideshow of images, with panning, zooming and crossfading ef- fects. To specify the directory that images are loaded from, run xscreensaver-set- tings(1) and click on the "Advanced" tab. OPTIONS --visual visual Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. --window Draw on a newly-created window. This is the default. --root Draw on the root window. --window-id number Draw on the specified window. --duration seconds How long each image will be displayed before loading a new one. Default 30 seconds. --transition seconds When a new image is loaded, it transitions onto the screen by slid- ing in from the edges, spinning or flipping. This is how long that transition takes. Set it to 0 to disable the transition effects. Default 3 seconds. --pan seconds Once an image has been loaded, it is panned, zoomed and cross-faded against itself. This is how fast those pans are. Set this to 0 to disable the panning-and-crossfading effect. Default 6 seconds. --fade seconds When zooming and cross-fading, this is how long the "fade" portion takes. This value must be less than the "pan" option (it is inclu- sive). Set this to 0 to disable the panning-and-crossfading ef- fect. Default 2 seconds. --letterbox Whether to fit the image on the screen (adding horizontal or verti- cal black bars) or to fill the screen (cropping the image). This is the default. --clip The opposite of --letterbox. --zoom number Zoom in on the image a little bit. This applies both to "transi- tions" and to "panning-and-crossfading". Default: 75, meaning that 75% or more of each image will always be visible. If you always want to see 100% of every image, then use "letterbox" and set "zoom" to 100%. --titles Whether to show the file name of the current image in the upper left corner. --delay number Per-frame delay, in microseconds. Default: 20000 (0.02 seconds). --fps Display the current frame rate, CPU load, and polygon count. --verbose Prints debugging info to stderr. --debug Draw some diagnostic rectangles. --wireframe Another debug mode. ENVIRONMENT DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global re- sources stored in the RESOURCE_MANAGER property. XSCREENSAVER_WINDOW The window ID to use with --root.
