Name: GRSLW Purpose: set line width Category: GRAPHICS File: pgplot.src Author: T.J. Pearson Use: see description below. Description: SUBROUTINE GRSLW (IW) INTEGER IW GRPCKG: Set the line width for subsequent plotting on the current device. If the hardware does not support thick lines, they are simulated by tracing each line with multiple strokes offset in the direction perpendicular to the line. The line width is specified by the number of strokes to be used, which must be in the range 1-201. The actual line width obtained depends on the device resolution. If the hardware does support thick lines, the width of the line is approximately 0.005 inches times the value of argument IW. Argument: IW (integer, input): the number of strokes to be used for subsequent plotting on the current device (in range 1-201). Updates: Oct 16, 1998: JPT automatically extracted from source.
