NAME
XSetLineAttributes − set the line drawing components in a graphics context.
Synopsis
XSetLineAttributes(display, gc, line_width, line_style,
cap_style, join_style)
Display *display;
GC gc;
unsigned int line_width;
int line_style;
int cap_style;
int join_style;
Arguments
displaySpecifies a connection to an X server; returned from XOpenDisplay().
gcSpecifies the graphics context.
line_width
Specifies the line width in the specified graphics context.
line_style
Specifies the line style in the specified graphics context. Possible values are LineSolid, LineOnOffDash, or LineDoubleDash.
cap_styleSpecifies the line and cap style in the specified graphics context. Possible values are CapNotLast, CapButt, CapRound, or CapProjecting.
join_style
Specifies the line-join style in the specified graphics context. Possible values are JoinMiter, JoinRound, or JoinBevel. If you specify JoinMitre, JoinBevel is used instead if the angle separating the two lines is less than 11 degrees.
Description
XSetLineAttributes() sets four types of line characteristics in the GC: line_width, line_style, cap_style, and join_style. See the description of line and join styles in Volume One, Chapter 5, The Graphics Context. See also XSetDashes(). A line_width of zero (0) means to use the fastest algorithm for drawing a line of one pixel width. These lines may not meet properly with lines specified as width one or more.
