IM-C-G3-FAX-BODY-PART
IM-C-G3-FAX-BODY-PART
This class of object consists of a G3 facsimile message.
Table 3-61
describes the attribute types for this class and the syntax, length, and number
of values for each type.
Meanings of Attributes
The attribute types specify the following information:
IM-T-G3-FAX-NBPS
Provides the nonbasic parameters of the images. This attribute is always present if the
interpersonal message (IPM) contains two or more G3 facsimile body parts. If only a
single body part is present, the nonbasic parameters might be conveyed instead by
means of the MH-T-ORIGINAL-EITS attribute of the message (or report) containing the
IPM.
IM-T-IMAGES
Are the G3 facsimile images: sequences of bit strings, each encoding a single page of
Group 3 facsimile data conforming to Recommendations T.4 and T.30. The minimum
length is 0, represented by one octet containing all zero bits.
Implementation and Usage Note
•
OM-S-ONFILE-STRING is a value syntax that applies to messages exceeding 64
kilobytes.
For the attribute MH-T-IMAGES, this value syntax is an alternative to OM-S-BIT-
STRING.
When this attribute has the syntax OM-S-ONFILE-STRING, the GPI library stores
the value in a file, and the value retains the characteristics of its primary syntax.
For outbound messages, the client program should specify OM-S-ONFILE-STRING
as the syntax of an attribute when the memory storage space might be insufficient to
accommodate the value of the attribute. The client can specify this syntax for
Table 3-61. IM-C-G3-FAX-BODY-PART Attributes—General Characteristics
