NAME

fblabel - display a text string on a framebuffer

CONTENTS

SYNOPSIS

fblabel [-hca] [-F framebuffer] [-f fontname] [-C r/g/b] x_position y_position text_string

DESCRIPTION

Fblabel writes a text string to the image on the currently selected framebuffer. The text string will be filtered to the image currently displayed. Use fbpoint(1) to determine where to position the text string. The lower left corner of the text string starts displaying at the x and y position given. The environment variable FB_FILE specifies the current framebuffer, see brlcad(1). Alternatively, the framebuffer may be explicitly specified by using the -F flag.

By default, the requested framebuffer size, is assumed to be 512x512 pixels. Specifying the -h flag changes the size to 1024x1024.

The -c flag causes the screen to be cleared before the text string is displayed. The default behavior is to label the current image without clearing the screen.

The -a The flag causes the text not to be filtered against the frame buffer image.

The -C r/g/b specifies red, green, and blue rgb values [0..255] for the text. The default color is white.

The -f fontname flag will change the current default font from nonie.r.12 to "/usr/lib/vfont/fontname".

FONTS

Fblabel expects the Berkley fonts in the directory /usr/lib/vfont. The fonts are expected to be in Vax byte order, even if that is not the natural byte order of the machine, to avoid having to create a font converter.

EXAMPLE

fblabel -h -f "oldenglish.14" ‘fbpoint -h‘ "Hello"
