VG_LINE(3) Library Functions Manual VG_LINE(3) NAME VG_Line -- agar-vg line entity SYNOPSIS #include <agar/core.h> #include <agar/gui.h> #include <agar/vg.h> DESCRIPTION VG_Line is a VG(3) node class which describes a line segment in terms of two points. INTERFACE VG_Line * VG_LineNew(VG_Node *parent, VG_Point *p1, VG_Point *p2) void VG_LineThickness(VG_Line *vl, Uint8 thickness) void VG_LineStipple(VG_Line *vl, Uint16 pattern) void VG_LineEndpointStyle(VG_Line *vl, enum vg_endpoint_style style, ...) The VG_LineNew() function creates a new line segment entity attached to parent. The p1 and p2 arguments define the endpoints. VG_LineThickness() defines the thickness of the line in pixels (default = 1 pixel). Note that the line thickness parameter does not influence proximity queries used by "select" tools. it only affects rendering, so very thick lines should be rendered as VG_Polygon(3) instead. VG_LineStipple() defines a 16-bit, OpenGL-style stipple pattern (de- fault is 0xffff). The order in which bits are used is undefined and depends on order of rendering. By default, thick lines are rendered using a square endpoint style. VG_LineEndpointStyle() specifies the style of endpoints to use in ren- dering the line. Acceptable values include: enum vg_line_endpoint { VG_LINE_SQUARE, /* Square endpoint */ VG_LINE_BEVELED, /* Beveled endpoint */ VG_LINE_ROUNDED, /* Rounded endpoint (circular) */ VG_LINE_MITERED /* Mitered endpoint */ }; If VG_LINE_MITERED is used, VG_LineEndpointStyle() expects a following Uint8 argument describing the miter length in pixels.
