Usage: ElectronicColoringBook.py [options] file
Colorize data file according to repetitive chunks, typical in ECB encrypted
data
Options:
-h, --help show this help message and exit
-c COLORS, --colors=COLORS
Number of colors to use, default=16
-P PALETTE, --palette=PALETTE
Provide list of colors to be used, as hex byte indexes
to a rainbow palette or as RGB palette
-b BLOCKSIZE, --blocksize=BLOCKSIZE
Blocksize to consider, in bytes, default=16
-g GROUPS, --groups=GROUPS
Groups of N blocks e.g. when blocksize is not multiple
of underlying data, default=1
-r RATIO, --ratio=RATIO
Ratio of output image, e.g. -r 4:3
-x WIDTH, --width=WIDTH
Width of output image, can be float e.g. to ignore
line PNG-filter byte
-y HEIGHT, --height=HEIGHT
Height of output image
-s SAMPLING, --sampling=SAMPLING
Sampling when guessing image size. Smaller is slower
but more precise, default=1000
-m MAXRATIO, --maxratio=MAXRATIO
Max ratio to test when guessing image size. E.g.
default=3 means testing ratios from 1:3 to 3:1
-o OFFSET, --offset=OFFSET
Offset to skip original header in number of blocks,
can be float
-f, --flip Flip image top<>bottom
-p PIXELWIDTH, --pixelwidth=PIXELWIDTH
How many bytes per pixel in the original image
-R, --raw Display raw image in 256 colors
-S, --save Save a copy of the produced image
-O OUTPUT, --output=OUTPUT
Change default output location prefix, e.g. -O
/tmp/mytest. Implies -S
-D, --dontshow Don't display image
