R = new_rect()
Creates a default CRect object
with properties initialized to the default values 0,0,0,0.
R = new_rect( CRect2 )
This
is a copy constructor. It creates a new CRect object
initialized to the properties of the CRect2 argument.
R = new_rect( xmin, xmax, ymin, ymax )
Creates a CRect object
initialized to xmin, xmax, ymin,
ymax.
R = CRect:Set( xmin, xmax, ymin, ymax )
Creates a new CRect object with
properties set to the numbers nXmin,
nXmax,
nYmin, and
nYmax. The
values may be positive or negative. If the rectangle will involve
working with images or arrays, then the values of nXmin and nXmax
should usually be 1.
R = new_rect( CImage )
Creates a new CRect object
initialized to the column and row dimensions of a CImage. The
rectangle will extend from 1 to CImage:Cols(), and 1 to
CImage:Rows().
R = new_rect( table )
Creates a new CRect object from the
first 4 values in a 1-dimensional array, in particular, the values
of table[1] through table[4]. These numbers are assigned in order
to the rectangle properties xmin, xmax, ymin, and ymax.
