Compatibility and Implementation Notes
3.10.2, “File Specification Dictionaries”
45. In Acrobat 5.0, file specifications accessed through
EmbeddedFiles
have a
Type
entry whose value is
F
instead of the correct
Filespec
. Acrobat 6.0
and later accept a file specification whose
Type
entry is either
Filespec
or
F
.
46. In certain situations, Acrobat 3.0 and greater do not correctly interpret file
specifications referenced by the
F
entry in Form or Image XObjects. Spe-
cifically, Acrobat ignores the file specification
EF
entry when that file spec-
ification is referenced from the XObject
F
entry.
Example H.1 shows an example of an Image XObject
F
entry referencing a
file specification that in turn references an embedded file. Acrobat does
not correctly interpret such file specifications.
Example H.1
13 0 obj <<
/Type /XObject
/Subtype /Image
/F 12 0 R
>> stream endstream endobj
12 0 obj <<
/Type /Filespec
/EF <</F 10 0 R>>
>> endobj
10 0 obj <<
/Type /EmbeddedFile
>> stream … endstream endobj
4.5.2, “Color Space Families”
47. If an Acrobat viewer encounters an unknown color space family name, it
displays an error specifying the name, but reports no further errors there-
after.
