sort

sort pixels along an axis

$ pierogis sort ./input.jpg -l 50 -u 180 --inner -t 1

very chill.

Use Sort to sort a selection of contiguous pixels in order of their brightness. The pixels to sort are selected using threshold.

-l and -u serve as lower and upper thresholds where groups of pixels with brightness outside of the thresholds are sorted. Providing --inner sorts values between these thresholds.

Use -t, -a, --clockwise, resample-filter to describe the direction of the sort. See rotate.

If only --lower-threshold is provided, --upper-threshold is set to 255. If only --upper-threshold is provided, --lower-threshold is set to 0.

arg	description	default	valid
-l, --lower-threshold	pixels with intensity <= this value are sorted	64	0-255
-u, --upper-threshold	pixels with intensity >= this value are sorted	180	0-255
--inner	if provided, pixels between (inclusive) the threshold values are included in the sort	False	0-255
-t, --turns	number of clockwise turns from sorting bottom to top	0	0-3
-a, --angle	degrees to rotate through each turn	90	int
--ccw	if provided, turns will be applied counter-clockwise instead	False	flag
--resample-filter	a filter to be used with rotating	'nearest'	str
