interesting puzzle!
Are you saying one has to "draw" an imaginary rectangle frame given the input coordinates?
I'm saying "imaginary", because the desired output coordinates are not in your input file.
Very interesting puzzle, but I'm not sure of the algorithm - it's definitely not what you tried.

complex
complex.h(3HEAD) Headers complex.h(3HEAD)
NAME
complex.h, complex - complex arithmetic
SYNOPSIS
#include <complex.h>
DESCRIPTION
The <complex.h> header defines the following macros:
complex Expands to _Complex.
_Complex_I Expands to a constant expression of type const float _Complex, with the value of the imaginary unit (that is, a number i
such that i2-1).
imaginary Expands to _Imaginary.
_Imaginary_I Expands to a constant expression of type const float _Imaginary with the value of the imaginary unit.
I Expands to either _Imaginary_I or _Complex_I. If _Imaginary_I is not defined, I expands to _Complex_I.
An application can undefine and then, if appropriate, redefine the complex, imaginary, and I macros.
USAGE
Values are interpreted as radians, not degrees.

NOTES
The choice of I instead of i for the imaginary unit concedes to the widespread use of the identifier i for other purposes. The application
can use a different identifier, say j, for the imaginary unit by following the inclusion of the <complex.h> header with:
#undef I
#define j _Imaginary_I
An I suffix to designate imaginary constants is not required, as multiplication by I provides a sufficiently convenient and more generally
useful notation for imaginary terms. The corresponding real type for the imaginary unit is float, so that use of I for algorithmic or nota-
tional convenience does not result in widening types.
On systems with imaginary types, the application has the ability to control whether use of the macro I introduces an imaginary type, by
explicitly defining I to be _Imaginary_I or _Complex_I.
Disallowing imaginary types is useful for some applications intended to run on implementations without support for such types.
The macro _Imaginary_I provides a test for whether imaginary types are supported. The cis() function (cos(x) + I*sin(x)) was considered but
rejected because its implementation is easy and straightforward, even though some implementations could compute sine and cosine more effi-
ciently in tandem.
