BrushStyle (2 bytes): A 16-bit unsigned integer that defines the brush style. The value MUST be an enumeration from the BrushStyle Enumeration table (section 2.1.1.4). For the meanings of the different values, see the following table.
ColorRef (4 bytes): A 32-bit field that specifies how to interpret color values in the object defined in the BrushHatch field. Its interpretation depends on the value of BrushStyle, as explained in the following table.
BrushHatch (variable): A variable-size field that contains the brush hatch or pattern data. The content depends on the value of BrushStyle, as explained below.
The BrushStyle field determines how the ColorRef and BrushHatch fields SHOULD be interpreted, as specified in the following table.
The following table shows the relationship between the BrushStyle, ColorRef, and BrushHatch fields in a Brush Object.
