XSetLineAttributes(3)		XLIB FUNCTIONS		 XSetLineAttributes(3)

NAME
       XSetLineAttributes, XSetDashes -	GC convenience routines

SYNTAX
       int XSetLineAttributes(Display *display,	GC gc, unsigned	int
	      line_width, int line_style, int cap_style, int join_style);

       int XSetDashes(Display *display,	GC gc, int dash_offset,	char
	      dash_list[], int n);

ARGUMENTS
       cap_style Specifies the line-style and cap-style	you want to set	for
		 the specified GC.  You	can pass CapNotLast, CapButt,
		 CapRound, or CapProjecting.

       dash_list Specifies the dash-list for the dashed	line-style you want to
		 set for the specified GC.

       dash_offset
		 Specifies the phase of	the pattern for	the dashed line-style
		 you want to set for the specified GC.

       display	 Specifies the connection to the X server.

       gc	 Specifies the GC.

       join_style
		 Specifies the line join-style you want	to set for the speci-
		 fied GC.  You can pass	JoinMiter, JoinRound, or JoinBevel.

       line_style
		 Specifies the line-style you want to set for the specified
		 GC.  You can pass LineSolid, LineOnOffDash, or	LineDou-
		 bleDash.

       line_width
		 Specifies the line-width you want to set for the specified
		 GC.

       n	 Specifies the number of elements in dash_list.

DESCRIPTION
       The XSetLineAttributes function sets the	line drawing components	in the
       specified GC.

       XSetLineAttributes can generate BadAlloc, BadGC,	and BadValue errors.

       The XSetDashes function sets the	dash-offset and	dash-list attributes
       for dashed line styles in the specified GC.  There must be at least one
       element in the specified	dash_list, or a	BadValue error results.	 The
       initial and alternating elements	(second, fourth, and so	on) of the
       dash_list are the even dashes, and the others are the odd dashes.  Each
       element specifies a dash	length in pixels.  All of the elements must be
       nonzero,	or a BadValue error results.  Specifying an odd-length list is
       equivalent to specifying	the same list concatenated with	itself to pro-
       duce an even-length list.

       The dash-offset defines the phase of the	pattern, specifying how	many
       pixels into the dash-list the pattern should actually begin in any sin-
       gle graphics request.  Dashing is continuous through path elements com-
       bined with a join-style but is reset to the dash-offset between each
       sequence	of joined lines.

       The unit	of measure for dashes is the same for the ordinary coordinate
       system.	Ideally, a dash	length is measured along the slope of the
       line, but implementations are only required to match this ideal for
       horizontal and vertical lines.  Failing the ideal semantics, it is sug-
       gested that the length be measured along	the major axis of the line.
       The major axis is defined as the	x axis for lines drawn at an angle of
       between -45 and +45 degrees or between 135 and 225 degrees from the x
       axis.  For all other lines, the major axis is the y axis.

       XSetDashes can generate BadAlloc, BadGC,	and BadValue errors.

DIAGNOSTICS
       BadAlloc	 The server failed to allocate the requested resource or
		 server	memory.

       BadGC	 A value for a GContext	argument does not name a defined GCon-
		 text.

       BadValue	 Some numeric value falls outside the range of values accepted
		 by the	request.  Unless a specific range is specified for an
		 argument, the full range defined by the argument's type is
		 accepted.  Any	argument defined as a set of alternatives can
		 generate this error.
