GETVIEWCOORD, GETVIEWCOORD

インテル® Fortran コンパイラー 19.0 デベロッパー・ガイドおよびリファレンス

Graphics Subroutines: Translate physical coordinates or window coordinates to viewport coordinates.

Module

USE IFQWIN

CALL GETVIEWCOORD (x, y, s)

CALL GETVIEWCOORD_W (wx, wy, s)

x, y

(Input) INTEGER(2). Physical coordinates to be converted to viewport coordinates.

wx, wy

(Input) REAL(8). Window coordinates to be converted to viewport coordinates.

(Output) Derived type xycoord. Viewport coordinates. The xycoord derived type is defined in IFQWIN.F90 as follows:

TYPE xycoord
  INTEGER(2) xcoord   ! x-coordinate
  INTEGER(2) ycoord   ! y-coordinate
END TYPE xycoord

Viewport coordinates refer to an area of the screen defined as the viewport with SETVIEWPORT. Physical coordinates refer to the whole screen. 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.
