line_set_pattern Function

public function line_set_pattern(line, factor, pattern) result(status)

Set a line's dash pattern, as OpenGL's line stipple: each bit of the 16-bit pattern (bit 0 first; z'FFFF' solid) covers factor window units (see shaders/line.vert). Returns 0, or -1 on failure.

Arguments

Type IntentOptional Attributes Name
type(c_ptr), intent(in) :: line

line handle
integer, intent(in) :: factor
integer, intent(in) :: pattern

Return Value integer(kind=c_int)
