SECTION 4.8
353
Images
have the same meanings as in a stream dictionary (Table 3.4 on page 62) or an
image dictionary (Table 4.39). Entries other than those listed are ignored; in par-
ticular, the
Type
,
Subtype
, and
Length
entries normally found in a stream or im-
age dictionary are unnecessary. For convenience, the abbreviations shown in the
table may be used in place of the fully spelled-out keys. Table 4.44 shows addi-
tional abbreviations that can be used for the names of color spaces and filters.
Note, however, that these abbreviations are valid only in inline images; they may
not
be used in image XObjects. Also note that
JBIG2Decode
and
JPXDecode
are
not listed in Table 4.44 because those filters can be applied only to image
XObjects.
