Graphics Subroutine: Converts viewport coordinates to window coordinates.
Module: USE IFQWIN
Syntax
CALL GETWINDOWCOORD (x, y, wt)
x, y
(Input) INTEGER(2). Viewport coordinates to be converted to window coordinates.
wt
(Output) Derived type wxycoord. Window coordinates. The wxycoord derived type is defined in IFQWIN.F90 as follows:
TYPE wxycoord
REAL(8) wx ! x-coordinate
REAL(8) wy ! y-coordinate
END TYPE wxycoord
Physical coordinates refer to the physical screen. Viewport coordinates refer to an area of the screen defined as the viewport with SETVIEWPORT. Both take integer coordinate values. Window coordinates refer to a window sized with SETWINDOW or SETWSIZEQQ. Window coordinates are floating-point values and allow easy scaling of data to the window area. For a more complete discussion of coordinate systems, see Building Applications: Understanding Coordinate Systems Overview.
