Header (variable): This MUST be a PresentationObjectHeader (section 2.2.1). The FormatID field of the Header MUST NOT be set to 0x00000000 and the ClassName field of the Header MUST be set to the case-sensitive values "METAFILEPICT", "BITMAP", or "DIB". The ClassName field identifies the type of the presentation data structure that follows the StandardPresentationObject.
Width (4 bytes): This MUST be set to the width of the presentation object. If the ClassName field of the Header is set to the case-sensitive value "METAFILEPICT", this MUST be a MetaFilePresentationDataWidth (section 2.1.8). If the ClassName field of the Header is set to either the case-sensitive value "BITMAP" or the case-sensitive value "DIB", this MUST be a DIBPresentationDataWidth (section 2.1.12).
Height (4 bytes): This MUST be set to the height of the presentation object multiplied by the LONG (as specified in [MS-DTYP] section 2.2.27) value -1. If the ClassName field of the Header is set to the case-sensitive value "METAFILEPICT", this MUST be a MetaFilePresentationDataHeight (section 2.1.9). If the ClassName field of the Header is set to either the case-sensitive value "BITMAP" or the case-sensitive value "DIB", this MUST be a DIBPresentationDataHeight (section 2.1.13).
