NAME
hsi_color_scale - Generation of color scale image
generated with program ras_to_hsi.
SYNOPSIS
hsi_color_scale <file_out> [nval] [chip_width]
[gap] [height]
| <file_out> | output (24-bit) SUN raster or BMP image file |
| [nval] | number of discrete color values to display 0: continuous color wheel (default) |
| [chip_width] | width of color chips (default=8) |
| [gap] | number of pixels between color chips (default=2) |
| [height] | height of color scale (default=chip_width) |
EXAMPLES
hsi_color_scale hsi.color_scale.ras 0 0 0 16
generates a continuous color scale (24-bit SUN
raster) with height=16.
hsi_color_scale hsi.color_scale.bmp 4 8 2
8
Generates a color scale (24-bit BMP format image) with 4 different colors, height=8.

DESCRIPTION
hsi_color_scale supports the generation of a color scale for a
hue/saturation/intensity (HSI) image generated using the program
ras_to_hsi. The
output is a 24-bit image with either a continuous color wheel or
a discrete number of color chips separated by black spaces.The
dimensions of the color chips and gaps may be selected to
facilitate the preparation of a color scale useful image
annotation in reports and presentations.
