FBFRAME(1)

NAME
fbframe - place a colored frame around a framebuffer

SYNOPSIS

fbframe [-F framebuffer] [-w|W frame_width] [-n|N frame_height] [-s|S squareframesize]

DESCRIPTION

fbframe places a colored frame around the edge pixels of a framebuffer. It is mostly for purposes of framebuffer alignment. The -F option can be used to specify the framebuffer. If this option is omitted, the environment variable FB_FILE is used to select the display device (see brlcad(1)). If the variable is not set, the default device for your system will be used.

The frame starts in the lower left with a red line running to the right to the next to last pixel. Next, a green line from there up to the next to top scan line is drawn. Then blue across the top scan line to the next to first column. Finally a white line down the left edge stopping just above the red line.

By default, the dimensions of the frame will be taken from the framebuffer used. Alternatively, one or more of the options -s, -w, -n (or -S, -W, -N) may be used to set the dimensions of the frame drawn.

The options -w (or -W) frame_width and -n (or -N) frame_height are used to specify the width (in pixels) and height (in scanlines) of the frame on the framebuffer respectively. The -s (or -S) squareframesize option specifies both the height and width of the frame to be drawn.
