DXF Types¶

Required DXF tag interface:

property code: group code as int

property value: tag value of unspecific type

dxfstr(): returns the DXF string

clone(): returns a deep copy of tag

DXFTag Factory Functions¶

ezdxf.lldxf.types.dxftag(code: int, value: TagValue) → ezdxf.lldxf.types.DXFTag ¶

DXF tag factory function.

Parameters

code – group code
value – tag value

Returns: DXFTag or inherited

ezdxf.lldxf.types.tuples_to_tags(iterable: Iterable[Tuple[int, TagValue]]) → Iterable[ezdxf.lldxf.types.DXFTag]¶: Returns an iterable if :class: DXFTag or inherited, accepts an iterable of (code, value) tuples as input.

DXFTag¶

class ezdxf.lldxf.types.DXFTag(code: int, value: TagValue)¶

Immutable DXFTag class - immutable by design, not by implementation.

Parameters

code – group code as int
value – tag value, type depends on group code

Variables

code – group code as int (do not change)
value – tag value (read-only property)

__eq__(other) → bool¶: True if other and self has same content for code and value.

__getitem__(index: int)¶: Returns code for index 0 and value for index 1, emulates a tuple.

__hash__()¶: Hash support, DXFTag can be used in sets and as dict key.

__iter__() → Iterable¶: Returns (code, value) tuples.

__repr__() → str¶: Returns representation string 'DXFTag(code, value)'.

__str__() → str¶: Returns content string '(code, value)'.

clone() → ezdxf.lldxf.types.DXFTag ¶: Returns a clone of itself, this method is necessary for the more complex (and not immutable) DXF tag types.

dxfstr() → str¶: Returns the DXF string e.g. ' 0\nLINE\n'

DXFBinaryTag¶

class ezdxf.lldxf.types.DXFBinaryTag(DXFTag)¶

Immutable BinaryTags class - immutable by design, not by implementation.

dxfstr() → str¶: Returns the DXF string for all vertex components.

tostring() → str¶: Returns binary value as single hex-string.

DXFVertex¶

class ezdxf.lldxf.types.DXFVertex(DXFTag)¶

Represents a 2D or 3D vertex, stores only the group code of the x-component of the vertex, because the y-group-code is x-group-code + 10 and z-group-code id x-group-code+20, this is a rule that ALWAYS applies. This tag is immutable by design, not by implementation.

Parameters

code – group code of x-component
value – sequence of x, y and optional z values

dxfstr() → str¶: Returns the DXF string for all vertex components.

dxftags() → Iterable[Tuple]¶: Returns all vertex components as single DXFTag objects.

NONE_TAG¶

ezdxf.lldxf.types.NONE_TAG¶: Special tag representing a none existing tag.
