NAME
     aloadimage - Trivial image viewer for Arcan servers

SYNOPSIS
     aloadimage [global_options] file1 file2 ...

DESCRIPTION
     aloadimage  displays  images  over an arcan connection point. Each image is
     parsed in a separate and sandboxed process. If  multiple  images  are  pro-
     vided, a certain number of items will be processed in advance.

OPTIONS
     -a, --aspect
	    image into output window, maintain source image aspect radio and pad
	    with a background color.

     -S, --server-size
	    Scale  source  images  to  fit  server- suggested content size. This
	    changes the primary type from MEDIA (server side scaling) to  APPLI-
	    CATION (client defined scaling).

     -l, --loop
	    When the playlist reaches the end, it will loop back from the begin-
	    ning rather than shutting down.

     -t, --step-time
	    Set  the  playlist	automatic stepping time (default: 0, manual con-
	    trol). The time unit is in ticks on a 25Hz clock.

     -b, --block-input
	    Ignore all keyboard and mouse input.

     -d, --display connpath
	    By default, the ARCAN_CONNPATH environment is used in order to  find
	    an arcan instance to connect to. This argument ignores that in favor
	    for the connpath argument.

     -p, --padcol ,g,b,a
	    When  running  in  a scalemode where source size != destination size
	    and output window cannot be resized, the default behavior is to cen-
	    ter image and pad the sides. This argument can override the  default
	    colors  with  the  restriction that all four channels should be pro-
	    vided and only decimal encoding in the range 0-255 is accepted.

     -m, --limit-mem limit(mb)
	    Limit the maximum decoded memory sized allowed for	eaching  loading
	    process.

     -r, --readahead limit(count)
	    Set  the  readahead  limit	for worker processes preloading playlist
	    contents.

     -T, --timeout timeout(seconds)
	    Stop/kill a worker process if it fails to decode an image  within  a
	    certain number of seconds.

     -x, --no-sysflt
	    (build-  option)  aloadimage may be built with syscall filtering for
	    worker processes. This may break  image  loading  in  some	environ-
	    ments/libc implementations and may therefore need to be disabled.

     -H, --vr
	    attempt to connect as a VR compatible output, requires that the lis-
	    tening  end  accepts  HMD_L/R  primary  and secondary segment types.
	    Playlist items should be prefixed with the	intended  dominant  eye,
	    e.g. l:image_l.jpg r:image_r.jpg.

     -h, --help
	    Show a brief summary of commands and usage.

ENVIRONMENT
     ARCAN_CONNPATH
	    Name of the connection point to use when connecting to arcan.

     ARCAN_CONNKEY
	    Key to use for authenticating againgst the connection path.
