NAME

fbcmrot - rotate the color map

CONTENTS

SYNOPSIS

fbcmrot [-h] [-i increment] steps_per_second

DESCRIPTION

Fbcmrot rotates the color map, cycling each color map entry through all of the color map positions. The frames_per_second is the number of shifts per second to generate. This value can be fractional. An unspecified frame rate causes the program to cycle through the color maps as fast as possible. A frames_per_second of zero causes the program to make one step and then exit.

Each step shifts the colormap one position toward smaller values (with a linear colormap this would cause displayed pixels to get brighter). The -iĀ increment option allows a shift of more than one position. If increment is negative, the colormap will be shifted the opposite direction (toward larger values).

By default, the framebuffer is assumed to be 512x512 pixels. Specifying the -h flag changes this to 1024x1024. This is only important for devices such as the Adage framebuffers which operate differently depending on the display size.
