Precision for -verbose -distort?
Posted: 2014-05-28T02:34:00-07:00
Can the "-verbose" output of "-distort" respect "-precision", please?
In particular I want to use the output from:
Two parameters in each direction are given to only one digit precision: "-0.000001" and "-0.000002".
The imprecision gives an error of a handful of coordinates in x- and y-direction in 5000x7500 images, which isn't a lot, but it fuzzes up images that I'd rather have correct.
(And maybe the spelling could be corrected to "equivalent".)
Thanks.
