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. = 1 will perform linear fit (scale and offset) = 2 will offset only without scaling 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.
