NAME

fbclear - clear a frame buffer image

CONTENTS

SYNOPSIS

fbclear [-c] [-F framebuffer] [red green blue]
fbclear [-c] [-F framebuffer] [gray_value]

DESCRIPTION

Fbclear is used to erase a frame buffer using whatever method is efficient for the device being accessed. By default, the selected color will be flooded into the color planes. If the -c option is used, a standard linear colormap will be loaded and the pan and zoom values will be reset.

If the optional color values are given, fbclear writes the specified color over the entire image. The color values must be in the range 0 to 255. In the second form shown above, the single gray_value is written into all three color channels.

The frame buffer to be cleared is determined from the -F option if given. Otherwise 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.

In addition to those flags shown above, the -W width -N height and -S square_size flags can be used to set the size of the output frame buffer.
