NAME

fbfade - fade a frame buffer image in or out

CONTENTS

SYNOPSIS

fbfade [-h] [-f input image name] [-s input square size] [-w input width]
  [-n input height] [-S output square size] [-W output width] [-N output height]
[[-F ] output frame buffer name]

DESCRIPTION

 fbfade gradually displays an image on a frame buffer, one randomly chosen pixel at a time.

    Options

 -h

(“high resolution”)Assumes 1024 by 1024 pixels for default input image size instead of 512 by 512. Explicitly specified sizes override the default, and if actual input image size is smaller than requested, the actual size will be used. If output frame buffer size is not specified, the revised input size will be requested for output. If actual output frame buffer size is greater than requested, only the lower-left portion of the frame buffer will be used. Actual sizes depend on details of specific frame buffers.

-f input image name

Inputs the image to be displayed from the specified frame buffer or pix(5) file, instead of using pure background (which fades out the image already on the output frame buffer).

-s input square size

Specifies input image width and height.

-w input width

Specifies input image width.

-n input height

Specifies input image height.

-S output square size

Specifies output frame buffer width and height.

-W output width

Specifies output frame buffer width.

-N output height

Specifies output frame buffer height.

-F output frame buffer name

Outputs to the specified frame buffer instead of the one specified by the  FB_FILE environment variable (or the default, if  FB_FILE is not set). If this is the last option specified, the  -F is optional.

CAVEAT

 fbfade works best in conjunction with a frame buffer having very fast access to pixels.

EXAMPLE

The following shell script can be used to produce a slick “slide show”:

fbclear for  i  in  *.pix do fbfade  -f $i sleep  15 done fbfade

SEE ALSO

libfb(3), pix(5).

DIAGNOSTICS

Error messages are intended to be self-explanatory.
