- Interface Summary
  Interface | Description
  --- | ---
  EscherProperties | Deprecated use `EscherPropertyTypes` enum instead
  EscherRecordFactory | The escher record factory interface allows for the creation of escher records from a pointer into a data array.
  EscherSerializationListener | Interface for listening to escher serialization events.

- Class Summary
  Class | Description
  --- | ---
  AbstractEscherOptRecord | Common abstract class for `EscherOptRecord` and `EscherTertiaryOptRecord`
  DefaultEscherRecordFactory | Generates escher records when provided the byte array containing those records.
  EscherArrayProperty | Escher array properties are the most weird construction ever invented with all sorts of special cases.
  EscherBitmapBlip |
  EscherBlipRecord |
  EscherBoolProperty | Represents a boolean property.
  EscherBSERecord | The BSE record is related closely to the `EscherBlipRecord` and stores extra information about the blip.
  EscherChildAnchorRecord | The escher child achor record is used to specify the position of a shape under an existing group.
  EscherClientAnchorRecord | The escher client anchor specifies which rows and cells the shape is bound to as well as the offsets within those cells.
  EscherClientDataRecord | The EscherClientDataRecord is used to store client specific data about the position of a shape within a container.
  EscherColorRef | An OfficeArtCOLORREF structure entry which also handles color extension opid data
  EscherComplexProperty | A complex property differs from a simple property in that the data can not fit inside a 32 bit integer.
  EscherContainerRecord | Escher container records store other escher records as children.
  EscherDggRecord | This record defines the drawing groups used for a particular sheet.
  EscherDggRecord.FileIdCluster |
  EscherDgRecord | This record simply holds the number of shapes in the drawing group and the last shape id used for this drawing group.
  EscherDump | Used to dump the contents of escher records to a PrintStream.
  EscherMetafileBlip |
  EscherOptRecord | The opt record is used to store property values for a shape.
  EscherProperty | This is the abstract base class for all escher properties.
  EscherPropertyFactory | Generates a property given a reference into the byte array storing that property.
  EscherPropertyMetaData | This class stores the type and description of an escher property.
  EscherRecord | The base abstract record from which all escher records are defined.
  EscherRGBProperty | A color property.
  EscherShapePathProperty | Defines the constants for the various possible shape paths.
  EscherSimpleProperty | A simple property is of fixed length and as a property number in addition to a 32-bit value.
  EscherSpgrRecord | The spgr record defines information about a shape group.
  EscherSplitMenuColorsRecord | A list of the most recently used colours for the drawings contained in this document.
  EscherSpRecord | Together the the EscherOptRecord this record defines some of the basic properties of a shape.
  EscherTertiaryOptRecord | "The OfficeArtTertiaryFOPT record specifies a table of OfficeArtRGFOPTE properties, as defined in section 2.3.1." -- [MS-ODRAW] -- v20110608; Office Drawing Binary File Format
  EscherTextboxRecord | Holds data from the parent application.
  NullEscherSerializationListener | Ignores all serialization events.
  UnknownEscherRecord | This record is used whenever a escher record is encountered that we do not explicitly support.

- Enum Summary
  Enum | Description
  --- | ---
  EscherColorRef.SysIndexProcedure | The following enum specifies values that indicate special procedural properties that are used to modify the color components of another color.
  EscherColorRef.SysIndexSource |
  EscherPropertyTypes | Provides a list of all known escher properties including the description and type.
  EscherPropertyTypesHolder |
  EscherRecordTypes |
