Functions ¶

func SectionTypeString ¶

func SectionTypeString(s SectionType) string

SectionTypeString converts SectionType to string. If SectionType is out of range, it returns empty string.

Types ¶

type Drawing ¶

type Drawing struct {
	FileName     string
	Layers       map[string]*table.Layer
	Groups       map[string]*object.Group
	Styles       map[string]*table.Style
	CurrentLayer *table.Layer
	CurrentStyle *table.Style

	Sections []Section

	PlotStyle handle.Handler
	// contains filtered or unexported fields
}

Drawing contains DXF drawing data.

func New ¶

func New() *Drawing

New creates a new Drawing.

func (*Drawing) AddEntity ¶

func (d *Drawing) AddEntity(e entity.Entity)

AddEntity adds a new entity.

func (*Drawing) AddLayer ¶

func (d *Drawing) AddLayer(name string, cl color.ColorNumber, lt *table.LineType, setcurrent bool) (*table.Layer, error)

AddLayer adds a new layer with given name, color and line type. If setcurrent is true, set current layer to it.

func (*Drawing) AddLineType ¶

func (d *Drawing) AddLineType(name string, desc string, ls ...float64) (*table.LineType, error)

AddLineType adds a new linetype.

func (*Drawing) AddStyle ¶

func (d *Drawing) AddStyle(name string, fontname, bigfontname string, setcurrent bool) (*table.Style, error)

AddStyle adds a new text style. If setcurrent is true, set current style to it.

func (*Drawing) AddToGroup ¶

func (d *Drawing) AddToGroup(name string, es ...entity.Entity) error

AddToGroup adds given entities to the named group. If the named group doesn't exist, returns error.

func (*Drawing) ChangeLayer ¶

func (d *Drawing) ChangeLayer(name string) error

ChangeLayer changes current layer to the named layer.

func (*Drawing) Circle ¶

func (d *Drawing) Circle(x, y, z, r float64) (*entity.Circle, error)

Circle creates a new CIRCLE at (x, y, z) with radius r.

func (*Drawing) Entities ¶

func (d *Drawing) Entities() entity.Entities

Entities returns slice of all entities contained in Drawing.

func (*Drawing) Group ¶

func (d *Drawing) Group(name, desc string, es ...entity.Entity) (*object.Group, error)

Group adds given entities to the named group. If the named group doesn't exist, create it.

func (d *Drawing) Header() *header.Header

func (*Drawing) Layer ¶

func (d *Drawing) Layer(name string, setcurrent bool) (*table.Layer, error)

Layer returns the named layer if exists. If setcurrent is true, set current layer to it.

func (*Drawing) Line ¶

func (d *Drawing) Line(x1, y1, z1, x2, y2, z2 float64) (*entity.Line, error)

Line creates a new LINE from (x1, y1, z1) to (x2, y2, z2).

func (*Drawing) LineType ¶

func (d *Drawing) LineType(name string) (*table.LineType, error)

LineType returns the named line type if exists.

func (*Drawing) LwPolyline ¶

func (d *Drawing) LwPolyline(closed bool, vertices ...[]float64) (*entity.LwPolyline, error)

LwPolyline creates a new LWPOLYLINE with given vertices.

func (*Drawing) Point ¶

func (d *Drawing) Point(x, y, z float64) (*entity.Point, error)

Point creates a new POINT at (x, y, z).

func (*Drawing) Polyline ¶

func (d *Drawing) Polyline(closed bool, vertices ...[]float64) (*entity.Polyline, error)

Polyline creates a new POLYLINE with given vertices.

func (*Drawing) Save ¶

func (d *Drawing) Save() error

Save saves the drawing file. If it is the first time, use SaveAs(filename).

func (*Drawing) SaveAs ¶

func (d *Drawing) SaveAs(filename string) error

SaveAs saves the drawing file as given filename.

func (*Drawing) SetExt ¶

func (d *Drawing) SetExt()

func (*Drawing) Style ¶

func (d *Drawing) Style(name string, setcurrent bool) (*table.Style, error)

Style returns the named text style if exists. If setcurrent is true, set current style to it.

func (*Drawing) Text ¶

func (d *Drawing) Text(str string, x, y, z, height float64) (*entity.Text, error)

Text creates a new TEXT str at (x, y, z) with given height.

func (*Drawing) ThreeDFace ¶

func (d *Drawing) ThreeDFace(points [][]float64) (*entity.ThreeDFace, error)

ThreeDFace creates a new 3DFACE with given points.

type Section ¶

type Section interface {
	WriteTo(format.Formatter)
	SetHandle(*int)
}

Section is interface for DXF sections.

type SectionType ¶

type SectionType int

SectionType represents Section names (code 2)

const (
	HEADER SectionType = iota
	CLASSES
	TABLES
	BLOCKS
	ENTITIES
	OBJECTS
	ACDSDATA
)

Section name: code 2

func SectionTypeValue ¶

func SectionTypeValue(s string) SectionType

SectionTypeValue converts string to SectionType. If string is unknown SectionType, it returns -1.
