From 21c4996c71d76b01a4333ef9905589b3fffa687d Mon Sep 17 00:00:00 2001 From: Daniel Friesel Date: Fri, 5 Feb 2010 17:52:34 +0100 Subject: Initial commit (upstream 1.3.4) --- feh.1 | 631 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 631 insertions(+) create mode 100644 feh.1 (limited to 'feh.1') diff --git a/feh.1 b/feh.1 new file mode 100644 index 0000000..254949e --- /dev/null +++ b/feh.1 @@ -0,0 +1,631 @@ +.TH feh 1 "August 14, 2001" +.SH NAME +feh - image viewer and cataloguer +.SH SYNOPSIS +feh [options] file(s) +.SH DESCRIPTION +.B feh +is an image viewer using the +.B imlib2 +library to open and manipulate images. +.B feh +has a large number of operational modes. The default mode is an image +slideshow, showing one image at a time from those specified on the +commandline. Keys and mouse control may be used to move through them. Other +modes can be specified on the commandline, and are described below. +.PP +.B feh +can also recurse through a directory structure to form a filelist for +processing, and will convert directory names on the commandline into a list +of their contents automatically. +.PP +.B Filelists +can be sorted in a number of ways. The default is the order the files were +specified on the commandline, or the order they were read from the disk. You +can specify sorting modes such as +.B +randomize +or you can sort by filename, image name, width, height, pixels, etc. +Filelists can also be saved to or loaded from files. +.SH MODES +.B Montage mode +forms a montage from the filelist. The resultant image can be viewed or +saved, and it's size can be limited by height, width or both. +.PP +.B Collage mode +is very similar to montage mode, except the images are distributed randomly +and may overlap eachother +.PP +.B Index mode +forms an index print from the filelist. Image thumbnails are shown along +with the filename, filesize and pixel size, printed using a truetype font of +your choice. The resultant image can be viewed or saved, and it's size can +be limited by height, width or both. +.PP +.B Thumbnail mode +is like index mode, but the mini-images are clickable, and launch the +clicked image in a browser window. +.PP +.B Multiwindow mode +shows images in multiple windows, instead of as a slideshow in one window. +Don't use with a large filelist ;) +.PP +.B Fullscreen mode +shows image in fullscreen view, can be combined with a slide-change delay to +show an automated presentation. +.PP +.B List mode +doesn't display images. Outputs an 'ls'-style listing of the files in the +filelist, including image info such as size, pixels, type, etc. Customlist +mode will display whatever image info you want, in the format you choose. +.PP +.B feh +can also list either all the loadable files in a filelist or all the +unloadable files. Useful for preening a directory. +.PP +.B feh +also has the ability to load files over http or ftp, simply specify the url +on the commandline. +.PP +.B feh +can read options from the commandline, or from a config file. The syntax +is the same in each case. See +.B CONFIG FILE SYNTAX +for details about using themes defined in a config file. +These methods may be used in conjunction. +.SH OPTIONS +.TP 5 +.B -h, --help +display help output and exit +.TP 5 +.B -v, --version +output version information and exit +.TP 5 +.B -V, --verbose +output useful information, progress bars, etc +.TP 5 +.B -q, --quiet +Don't report non-fatal errors for failed loads. Verbose and quiet modes +are not mutually exclusive, the first controls informational messages, +the second only errors. +.TP 5 +.B -T, --theme THEME +Load options from config file with name THEME - see CONFIG FILE SYNTAX for more info. +.TP 5 +.B --rcfile FILE +Use FILE to parse themes and options from, +instead of the default ~/.fehrc, /etc/fehrc files. +.TP 5 +.B -r, --recursive +Recursively expand any directories in FILE to the content of those +directories, all the way down to the bottom level. (Take it easy) +.TP 5 +.B -z, --randomize +When viewing multiple files in a slideshow, randomise the file list before +displaying. +.TP 5 +.B -f, --filelist FILE +This option is similar to the playlists used by music software. If FILE +exists, it will be read for a list of files to load, in the order they +appear. The format is a list of image filenames, absolute or relative to the +current directory, one filename per line. +.br +If FILE doesn't exist, it will be created from the internal filelist at the +end of a viewing session. This is best used to store the results of complex +sorts (-Spixels for example) for later viewing. Any changes to the internal +filelist (such as deleting a file or it being pruned for being unloadable) +will be saved to FILE when feh exits. You can add files to filelists by +specifying them on the commandline when also specifying the list. +.TP 5 +.B -p, --preload +Preload images. This doesn't mean hold them in RAM, it means run through +them and eliminate unloadable images first. Otherwise they will be removed +as you flick through. This also analyses the images to get data for use in +sorting, such as pixel size, type etc. A preload run will be automatically +performed if you specify one of these sort modes. +.TP 5 +.B -F, --full-screen +Make the window fullscreen +.TP 5 +.B -g, --geometry STRING +Limit (and don't change) the window size. Takes +an X-style geometry string like 640x480. +Note that larger images will be zoomed out to fit +but you can see them at 1:1 by clicking the zoom +button. +.TP 5 +.B -Z, --auto-zoom +Zoom picture to screen size in fullscreen (affected by --stretch and +--ignore-aspect). +.TP 5 +.B --zoom PERCENT +Zooms images by a PERCENT, when in full screen mode or when window geometry +is fixed. If combined with --auto-zoom, zooming will be limited to the the +size. +.TP 5 +.B -w, --multiwindow +Disable slideshow mode. With this setting, instead of opening multiple +files in slideshow mode, multiple windows will be opened, one per file. +.TP 5 +.B -x, --borderless +Create borderless windows +.TP 5 +.B -d, --draw-filename +Draw the filename at the top-left of the image +.TP 5 +.B -D, --slideshow-delay NUM +For slideshow mode, specifies time delay (seconds, can be a decimal) between automatically +changing slides. Great for presentations. +.TP 5 +.B -R, --reload NUM +Use this option to tell +.B feh +to reload an image after NUM seconds. Useful for viewing webcams via http, +or even on your local machine. +.TP 5 +.B -k, --keep-http +When viewing files using HTTP, feh normally deletes the local copies after +viewing, or, if caching, on exit. This option prevents this so that you +get to keep the local copies. They will be in /tmp with "feh" in the name. +.TP 5 +.B -Q, --builtin +Use builtin http client to grab remote files instead of wget, useful if you +don't have wget installed. +.TP 5 +.B --caption-path PATH +Path to directory containing image captions. This turns on caption viewing, and +if captions are found in PATH, which is relative to the directory of each +image, they are overlayed on the displayed image. e.g with caption path +"captions", and viewing image images/foo.jpg, caption will be looked for as +"images/captions/foo.jpg.txt" +.TP 5 +.B -l, --list +Don't display images. Analyse them and display an 'ls'-style listing. +Useful in scripts hunt out images of a certain size/resolution/type etc. +.TP 5 +.B -L, --customlist FORMAT +Use FORMAT as the format specifier for list +output. FORMAT is a printf-like string containing +image info specifiers. See FORMAT SPECIFIERS. +.TP 5 +.B -U, --loadable +Don't display images. Just print out their names if imlib2 can successfully +load them. +.TP 5 +.B -u, --unloadable +Don't display images. Just print out their name if imlib2 can NOT +successfully load them. +.TP 5 +.B -S, --sort SORT_TYPE +The file list may be sorted according to image parameters. Allowed sort +types are: name, filename, width, height, pixels, size, format. For sort +modes other than name or filename, a preload run will be necessary, +causing a delay proportional to the number of images in the list +.TP 5 +.B -n, --reverse +Reverse the sort order. Use this to invert the order of the filelist. Eg +to sort in reverse width order, use +.B -nSwidth +.TP 5 +.B -A, --action ACTION +Specify a string as an action to perform on the image. In slideshow or +multiwindow modes, the action will be run when the enter key is pressed, in +list mode, the action will be run for each file listed. The action will be +executed by /bin/sh. Use format specifiers to refer to image info. See +FORMAT SPECIFIERS for examples +.br +Eg. feh -A "mv %f ~/images/%n" * +.br +In slideshow mode, the next image will be shown after running the action, +in multiwindow mode, the window will be closed. +.TP 5 +.B --action1...9 +Extra actions which can be set and triggered using the appropriate number +key. +.TP 5 +.B -m, --montage +Enable montage mode. Montage mode creates a new image consisting of a grid +of thumbnails of the images in the filelist. When montage mode is selected, +certain other options become available. See MONTAGE MODE OPTIONS +.TP 5 +.B -c, --collage +Enable collage mode. Collage mode is very similar to montage mode, except +the images are distributed randomly. +.TP 5 +.B -i, --index +Enable Index mode. Index mode is similar to montage mode, and accepts the +same options. It creates an index print of thumbails, printing the image +name beneath each thumbnail. Index mode enables certain other options, see +INDEX MODE OPTIONS +.TP 5 +.B -I, --fullindex +Same as Index mode, but you also get image size and dimensions printed +below each thumbnail. +.TP 5 +.B -t, --thumbnails +Same as Index mode, but the thumbnails are clickable image launchers. +.TP 5 +.B --bg-tile FILE +.TP 5 +.B --bg-center FILE +.TP 5 +.B --bg-scale FILE +.TP 5 +.B --bg-seamless FILE +Set your desktop background to FILE. Feh +can use enlightenment IPC if you are running +it, or will fall back to X methods. +Feh stores the commandline necessary to restore +the background you chose in ~/.fehbg. So to have +feh-set backgrounds restored when you restart X, +add the line "eval `cat $HOME/.fehbg`" to your +X startup script (e.g. ~/.xsession). Note that +you only need to do this for non E window +managers. +.TP 5 +.B -M, --menu-font FONT +Use FONT for the font in menus. +.TP 5 +.B --menu-style FILE +Use FILE as the style descriptor for menu text. +.TP 5 +.B --menu-bg BG +Use BG for the background image in menus. +.TP 5 +.B --menu-border INT +Specify number of pixels that define the menu +background's border. Borders are not stretched +when images are scaled. +.TP 5 +.B -N, --no-menus +Don't load or show any menus. +.TP 5 +.B -1, --next-button B +Use button B to advance to the next image in slideshow +mode (defaults to 1, usually the left button). +.TP 5 +.B -2, --zoom-button B +Use button B to zoom the current image in any +mode (defaults to 2, usually the middle button). +.TP 5 +.B -3, --pan-button B +Use button B to pan the current image in any mode (defaults to 3, usually the right button). +.TP 5 +.B --no-pan-ctrl-mask +Don't require CTRL+Button for panning in any mode -- just use the button (default=off). +.TP 5 +.B -4, --menu-button B +Use CTRL+Button B to activate the menu in any mode. Set to 0 to use any +button. This option is disabled if the -N or --no-menus option is set +(defaults to 3, usually the right button). +.TP 5 +.B -5, --no-menu-ctrl-mask +Don't require CTRL+Button for menu activation in any mode -- just use the button (default=off). +.TP 5 +.B -6, --rotate-button B +Use CTRL+Button B to rotate the current image in any mode (default=2). +.TP 5 +.B -7, --no-rotate-ctrl-mask +Don't require CTRL+Button for rotation in any mode -- just use the button (default=off). +.TP 5 +.B -8, --blur-button B +Use CTRL+Button B to blur the current image in any mode (default=1). +.TP 5 +.B -9, --no-blur-ctrl-mask +Don't require CTRL+Button for blurring in any mode -- just use the button (default=off). +.TP 5 +.B --xinerama +Enable/disable Xinerama support. Has no effect unless you have an Xinerama compiled in. +.TP 5 +.B --screen-clip +Enable/disable window clipping based on screen size. WARNING: With this disabled, windows could become very large, making them unmanageable in certain window managers. +.TP 5 +.B --hide-pointer +Hide the mouse pointer in full screen mode (useful for slideshows etc). +.SH FORMAT SPECIFIERS +.B %f +image path/filename +.br +.B %n +image name +.br +.B %s +image size (bytes) +.br +.B %p +image pixel size +.br +.B %w +image width +.br +.B %h +image height +.br +.B %t +image format +.br +.B %P +prints feh +.br +.B %v +prints the version +.br +.B %m +prints the mode (slideshow, multiwindow...) +.br +.B %l +prints the total number of files in the filelist +.br +.B %u +prints the current file number +.br +.nf +\\n newline +.fi +.br +Eg. feh -A "mv %f ~/images/%n" * +.SH MONTAGE MODE OPTIONS +.TP 5 +.B -X, --ignore-aspect +By default, the montage thumbnails will retain their aspect ratios, while +fitting in --thumb-width and --thumb-height. This option will force them to +be the size set by --thumb-width and --thumb-height This will prevent any +whitespace in the final montage +.TP 5 +.B -s, --stretch +Normally, if an image is smaller than the specified thumbnail size, it will +not be enlarged. If this option is set, the image will be scaled up to fit +the thumnail size. (Aspect ratio will be maintained unless --ignore-aspect is +specified) +.TP 5 +.B -y, --thumb-width NUM +Set thumbnail width in pixels +.TP 5 +.B -E, --thumb-height NUM +Set thumbnail height in pixels +Thumbnails default to 20x20 pixels +.TP 5 +.B -W, --limit-width NUM +Limit the width of the montage in pixels +.TP 5 +.B -H, --limit-height NUM +Limit the height of the montage in pixels These options can be used together +(to define the image size exactly), or separately. If only one is specified, +theother is calculated from the number of files specified and the size of +the thumbnails. The default is to limit width to 800 pixels and calculate +the height as necessary +.TP 5 +.B -b, --bg FILE|trans +Use FILE as a background for your montage. With this option specified, the +size of the montage will default to the size of FILE if no size restrictions +are specified. Alternatively, if FILE is 'trans', the background will be +made transparent. +.TP 5 +.B -a, --alpha NUM +When drawing thumbnails onto the background, apply them with a transparency +level of NUM (0-255). +.TP 5 +.B -o FILE +Save the created montage to FILE +.TP 5 +.B -O FILE +Just save the created montage to FILE without displaying it (use in scripts) +.SH INDEX MODE OPTIONS +.TP 5 +.B -e, --font FONT +Use FONT to print the information under each thumbnail. FONT should be a +truetype font, resident in the current directory, or in feh's font +directory, and should be defined in the form fontname/size(points). (No +extension). eg. --font myfont/12 +.TP 5 +.B --fontpath PATH +Specify PATH as an extra directory in which to search for fonts, can use +multiple times to add multiple paths, e.g --fontpath /path/a --fontpath +/path/b. +.TP 5 +.B --title-font FONT +Use FONT to print a title on the index, if no font is specified, a title +will not be printed +.SH CONFIG FILE SYNTAX +The feh config file allows the naming of option groups, or themes. +If +.B $HOME/.fehrc +exists, or if not, but +.B /etc/fehrc +exists, feh will look in it for theme name/options pairs. If neither +$HOME/.fehrc or /etc/fehrc exist, feh will create a default one in ~/.fehrc. +An example entry would be: +.br +.B imagemap -rVq --thumb-width 40 --thumb-height 30 +.br +You can then use this theme in two ways. Either +.br +.B feh --theme imagemap *.jpg +.br +or you can create a symbolic link to feh with the name of the options you +want it to use. So from the example above: +.br +.B ln -s `which feh` ~/bin/imagemap +.br +Now I just run +.B imagemap *.jpg +to use those options. A cooler example is +.br +.B mkindex -iVO index.jpg --title-font 20thcent/24 . +.br +Notice the '.' at the end. Now with a symlink I can create a mkindex +command which will create an index.jpg in the current directory. I just +run +.B mkindex +to do it. +.br +You can combine these themes with commandline options, they will be +combined. So in the example above, typing +.B mkindex -q +will create and index, suppressing error messages. +An example.fehrc is provided with a couple of cool examples. +.SH SLIDESHOW KEYS +The default mode for viewing mulitple images is Slideshow mode +When viewing a slideshow, the following keys may be used: +.TP 5 +.B p, P, , +Goto previous slide +.TP 5 +.B n, N, , +Goto next slide +.TP 5 +.B r, R +Reload current image. Useful for webcams. +.TP 5 +.B v, V +Toggle fullscreen. +.TP 5 +.B m, M +Show popup menu. +.TP 5 +.B c, C +Caption entry mode. If --caption-path has been specified, then this enables +caption editing. The caption will turn yellow and be editable, hit enter to +confirm and save the caption, or hit escape to cancel and revert the caption. +.TP 5 +.B w, W +Size window to current image size. +.TP 5 +.B h, H +Pause the slideshow (only useful when using +timed reloading or image changes) +.TP 5 +.B s, S +Save the current image to a unique filename. +.TP 5 +.B f, F +Save the current filelist to a unique filename. +.TP 5 +.B <, > +In place editing, rotate the image 90 degrees left/right. +.TP 5 +.B +Goto first slide +.TP 5 +.B +Goto last slide +.TP 5 +.B +Go forward around 5% of the way through the slideshow +.TP 5 +.B +Go backward around 5% of the way through the slideshow +.TP 5 +.B +Quit the slideshow +.TP 5 +.B +, = +Increase reload delay +.TP 5 +.B -, _ +Decrease reload delay +.TP 5 +.B +Remove the currently viewed file from the filelist +.TP 5 +.B +Delete the currently viewed file and remove it from the filelist +.TP 5 +.B x, X +Close current window. +.TP 5 +.B q, Q +Quit the slideshow +.B +Move the image to the left +.B +Move the image to the right +.B +Zoom in +.B +Zoom out +.B +Zoom to 100% +.B +Zoom to fit the window +.SH MOUSE ACTIONS +When viewing an image, mouse button 1 moves to the next image (slideshow +mode only), button 2 zooms (click and drag left->right to zoom in, right-> +left to zoom out, click once to restore 1x zoom), and mouse button 3 pans. +Ctrl+button 1 blurs or sharpens the image (drag left to blur and right to +sharpen). Ctrl+button 2 rotates the image around the center point. Ctrl+ +button 3 activates the context-sensitive menu. Buttons can be redefined +with the -1 through -9 (or --*-button) cmdline flags. All you people +with million button mice can remove the ctrl mask with the --no-*-ctrl-mask +options. +.SH SUGGESTED USAGE EXAMPLES +Here are some examples of nice option combinations to achieve cool results: +.TP 5 +.B feh -r /opt/images +Recursively scan /opt/images and show all the images in a slideshow. +.TP 5 +.B feh -rSname /opt/image +Same again, but sort by name before showing. +.TP 5 +.B feh -m /opt/images/landscapes +Create a montage from the images in /opt/images/landscapes +.TP 5 +.B feh -Xrm -W 400 --thumb-width 30 --thumb-height 20 ./landscapes +Create a montage from the images in /opt/images/landscapes and all +directories below it. Limit the width of the image to 400 and make the +thumbnails 30x20, ignoring aspect ratio. +.TP 5 +.B feh -irFarial/14 -O index.jpg /opt/images +Make an index print of /opt/images and all directories below it, using 14 +point arial to write the image info under each thumbnail. Save the image as +index.jpg and don't display it, just exit. +.TP 5 +.B feh -LrSpixels /opt/images +List the images in /opt/images and all directories within, sorted by pixel +size, giving as much info as possible. +.TP 5 +.B feh -kR30 http://url.of.a.webcam.jpg +Use feh to view a webcam, reloading every 30 seconds, and saving the images +in /tmp. +.TP 5 +.B feh --unloadables -r /opt/images +Weed out (list) all the unloadable images in /opt/images and below. +.TP 5 +.B feh -w /opt/images/holidays +Open each image in /opt/images/holidays in it's own window +.TP 5 +.B feh -FD5 -Sname /opt/images/presentation +Show the images in /opt/images/presentation, sorted by name, in fullscreen +view, automatically changing slides every 5 seconds. +.TP 5 +.B feh -rSwidth -A 'mv %f ~/images/%n\' /opt/images +View all the images in /opt/images and below, sorted by width (smallest +first) and move the image to ~/images/image_name when enter is pressed. +.SH BUGS +None known.
