Description Match contrast and levels from one v_object to another
Arguments and Return Values Arguments: Accepts two v_objects, an ignore value and an option. Return Values: Modifies the src v_object but returns no values to the user.
Usage Syntax: v_insert(obj = STRUCT, to = STRUCT [, ignore = FLOAT] [, opt = INT]) obj - First v_object which will have its values modified in the overlapping regions to - Second v_object that the first v_object will be adjusted to. ignore - Value that is not data. Default is -32768. opt - Type of level adjustment desired. Default is 1.
Examples dv> a
struct, 7 elements
data: 500x300x1 array of byte, bsq format [150,000 bytes]
h: 300
lines: 0
samples: 0
w: 500
x: 0
y: 0
dv> b
struct, 7 elements
data: 500x300x1 array of byte, bsq format [150,000 bytes]
h: 300
lines: 0
samples: 0
w: 500
x: 250
y: 150
dv> d = level_adjust(src=a,dst=b,ignore=0)
Images The left image is before, the middle image is the image the first image will be adjusted to, and the thrid image is the adjusted image.
