NAME
gray_wedge - generate a gray value ramp image
SYNOPSIS
gray_wedge
-r rows -w cols -m upper_value [-b, -s, -i, -f] -n num_frames
DESCRIPTION
gray_wedge
produces a frame (or sequence) in which the pixel values go from 0 to upper_value
from right to left (increasing col number). The pixels are constant
from top to bottom (along cols). The pixel format may be byte, short,
int, or float.
OPTIONS
- -r
-
rows
(%d)
(default = 512): give the number of row in the image.
- -w
-
columns
(%d) (default = 512): give the number of columns in the image.
- -m
-
max_value
(%d or %f) - maximum pixel value (default is maximum for the unsigned data type,
e.g. 255 for byte, 65535 for short, 4294967295 for int. 1.0 is used for
float format pixels). An integer is required for -b, -s, and -i output,
a float for -f output.
- -b
-
byte (unsigned) pixel format output (the default) (HIPS type PFBYTE)
- -s
-
short (unsigned) pixel format output (HIPS type PFSHORT)
- -i
-
integer (unsigned) pixel format output (HIPS type PFINT)
- -f
-
float pixel format output (HIPS type PFFLOAT)
- -n
-
number_of_frames
(%d) - number of frames to output in a sequence (default = 1)
