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)
