|
||
|
|
:attr:`elflags`
|
||
|
|
Element flags (:class:`int`, optional).
|
||
|
|
Bit 15 specifies template data.
|
||
|
|
Bit 14 specifies external data.
|
||
|
|
:attr:`plex`
|
||
|
|
Plex number (:class:`int`, optional).
|
||
|
|
:attr:`layer`
|
||
|
|
Element layer (:class:`int`)
|
||
|
|
:attr:`data_type`
|
||
|
|
Element data type (:class:`int`)
|
||
|
|
:attr:`path_type`
|
||
|
|
Type of path endpoints (:class:`int`, optional).
|
||
|

|
Width of the path (:class:`int`, optional). If the value is negative,
|
||
|
|
then the width is absolute and not affected by magnification factor.

|
||
|
|
Name of the referenced structure (:class:`bytes`).
|

|
||
|
|
* 0 -- reclection about X axis
|
||
|
|
* 13 -- absolute magnification
|
||
|
|
* 14 -- absolute angle
|
||
|
|
:attr:`mag`
|
||
|
|
Magnification factor (:class:`float`, optional).
|
||
|
|
:attr:`angle`
|
||
|
|
Rotation factor in degrees (:class:`float`, optional). Rotation is counterclockwise.
|
||

|
||
|
|
:attr:`presentation`
|
||
|

|
String for :const:`TEXT` element (:class:`bytes`).
|
||
|
|
:attr:`node_type`

|
||
|
|
Box type (:class:`int`).
|
||
|
|
:attr:`properties`
|
||
|
|
Element properties, represented as a list of tupes (`propattr`, `propvalue`).
|
||
|
|
`propattr` is an :class:`int`, `propvalue` is :class:`bytes`.
