<B>WINDOW Redefine Screen Coordinates</B>
|
|
|
|
<B>WINDOW</B> [[SCREEN](<U>x1</U>,<U>y1</U>)-(<U>x2</U>,<U>y2</U>)]
|
|
|
|
Specifies "world" coordinates for the screen.
|
|
|
|
SCREEN If omitted, <U>x1</U>,<U>y1</U> and <U>x2</U>,<U>y2</U> specify the upper left and
|
|
lower right corners of the world space, respectively. If
|
|
included, <U>x1</U>,<U>y1</U> and <U>x2</U>,<U>y2</U> specify the lower left and upper
|
|
right corners of the world space, respectively.
|
|
|
|
<U>x1</U>,<U>y1</U>,<U>x2</U>,<U>y2</U> The corner coordinates of the world space.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
<B>Notes:</B> The WINDOW statement allows you to redefine the corners of
|
|
the display screen as a pair of "world" coordinates.
|
|
Because objects plotted by subsequent graphics statements
|
|
are still plotted in the standard "physical" coordinates,
|
|
the WINDOW statement provides a way of scaling, rotating,
|
|
and/or transposing such objects.
|
|
|
|
BASIC sorts the coordinates so that the lower of <U>x1</U> and <U>y1</U>
|
|
will be treated as <U>x1</U> and the lower of <U>y1</U> and <U>y2</U> will be
|
|
treated as <U>y1</U>, regardless of how the coordinates are
|
|
presented. Thus WINDOW (280,120)-(140,180) would be
|
|
equivalent to WINDOW (140,120)-(280,180).
|
|
|
|
A world space defined by WINDOW is disabled by a RUN
|
|
statement, a change in SCREEN attributes, or a WINDOW
|
|
statement with no arguments.
