NAME
checkers2 - generate a checker board pattern of gray values
SYNOPSIS
checkers2
-hi_gray -lo_gray -np_col -np_row -r rows -c cols [-b, -s, -i, -f] -n num_frames
Defaults:
hi_gray: 128; lo_gray: 0; np_col:10; np_row:10; rows: 512; cols: 512; byte output; frames: 1
DESCRIPTION
Checker
produces a frame (or sequence) which contains a checker board of gray value patches.
OPTIONS
- -hi_gray bright_patch_value
-
(%d or %f)
(default = 50% of maximum for the pixel type chosen (0.5 for PFFLOAT))
- -lo_gray dim_patch_value
-
(%d or %f)
(default = 0)
- -np_col num_patches
-
(%d)
(default = 10): number of patches in the column direction (across)
- -np_row num_patches
-
(%d)
(default = 10): number of patches in the row direction (down)
- -r rows
-
(%d)
(default = 512): the number of rows in the image.
- -c colums
-
(%d)
(default = 512): the number of colums in the image.
- -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)
