.TH fbview 1 "13 November 1998" \" -*- nroff -*-
.SH NAME
fbview \- display various picture formats on a framebuffer
.SH SYNOPSIS
.B fbview
[options] file [file2...]
.SH DESCRIPTION
Reads at least one graphic file as input, and renders it (or them,
in sequence) to a free virtual terminal. You must specify at least
one filename. This requires the
.B ppmtofb
program and
.B netpbm
to work.
.SH OPTIONS
.TP
.B "\-h, \-\-help"
Show a brief summary of the options permitted.
.TP
.B "\-v, \-\-verbose"
Write information about each image to stderr.
.TP
.B "\-q, \-\-quiet"
Don't write information about each image to stderr.
.TP
.B "\-V, \-\-ppmtofb\-verbose"
Tell
.B ppmtofb
to be verbose too.
.TP
.B "\-c, \-\-center, \-\-centre"
Center the image on the visible display area (if possible).
.TP
.B "\-\-no\-center, \-\-no\-centre"
Don't center the image on the visible display area.
.TP
.B "\-w, \-\-delay, \-\-pause"
Set the mininum delay between images, in seconds. (Default: 5). Note
that the time an image is displayed while another is loading is
included in this delay period (so if it takes longer than the delay
period to load the next image, the delay will be extended).
.TP
.B "\-d, \-\-depth, \-\-bpp"
Set the color depth for images. Defaults to the depth of the current mode.
.TP
.B "\-g, \-\-grayscale, \-\-greyscale"
Render all images in grayscale. This can be significantly faster than
color display on low-color displays.
.TP
.B "\-C, \-\-color, \-\-colour"
Render non-grayscale images in color.
.TP
.B "\-m, \-\-maxcolors, \-\-maxcolours"
If non-zero, run
.B ppmquant
on images to reduce them to, at most, this many colors. (Default: 0)
.TP
.B "\-W, \-\-width"
Tell
.B fbview
how wide your display is; if the image width is greater than this
width, the image will be scaled appropriately. (Default: 640)
.TP
.B "\-H, \-\-height"
Tell
.B fbview
how high your display is; if the image height is greater than this
height, the image will be scaled appropriately. (Default: 480)
.TP
.B "\-f, \-\-framebuffer, \-\-frame\-buffer"
Specify the framebuffer device to use. This defaults to
.BR /dev/fb0 .
.SH CONFIGURATION
.B fbview
reads a configuration file from /etc/fbview.conf or .fbview.conf in
the user's home directory which overrides its default settings. See
the example in /usr/doc/ppmtofb/examples/fbview.conf for details.
.SH BUGS
Only supports certain file formats.
