NAME

fb-pix - save a framebuffer image in a color pix file

CONTENTS

SYNOPSIS

fb-pix [-hic] [-F framebuffer] [-s squaresize] [-w width] [-n height] [file.pix]

DESCRIPTION

Fb-pix will take a region of a framebuffer display and save it as a color pix(5) format file. The environment variable

FB_FILE is used to select the display device (see brlcad(1)). If this variable is not set, the default device for your system will be used. Alternatively, the framebuffer may be explicitly specified by using the -F flag.

By default, the output pix file, and the requested framebuffer size, is assumed to be 512x512 pixels. Specifying the -h flag, changes the default to 1024x1024. The -s flag will set both the file height and width to be the given size, while -w and -n sets them individually.

A first quadrant coordinate system is used (origin in lower left of screen), and the area saved is normally from this origin. The -i flag switches to a fourth quadrant system, both in the storage order as well as the origin offset coordinates (i.e. origin is now the upper left corner of the screen).

The -c flag specifies that the color map in the frame buffer should be applied to the pixel values (“crunched”) before they are written to the output file.
