SETVIEWPORT (W*S)

インテル® Fortran コンパイラー 14.0 ユーザー・リファレンス・ガイド

Graphics Subroutine: Redefines the graphics viewport by defining a clipping region in the same manner as SETCLIPRGN and then setting the viewport-coordinate origin to the upper-left corner of the region.

モジュール

USE IFQWIN

CALL SETVIEWPORT (x1,y1,x2,y2)

x1, y1	(Input) INTEGER(2). Physical coordinates for upper-left corner of viewport.
x2, y2	(Input) INTEGER(2). Physical coordinates for lower-right corner of viewport.

The physical coordinates (x1, y1) and (x2, y2) are the upper-left and lower-right corners of the rectangular clipping region. Any window transformation done with the SETWINDOW function is relative to the viewport, not the entire screen.

例

 USE IFQWIN

 INTEGER(2) upx, upy

 INTEGER(2) downx, downy

 upx = 0

 upy = 30

 downx= 250

 downy = 100

 CALL SETVIEWPORT(upx, upy, downx, downy)
