TIFFSetDirectory changes the current directory and
|
|
Packit |
85355f |
reads its contents with TIFFReadDirectory. The
|
|
Packit |
85355f |
parameter dirnum specifies the subfile/directory as
|
|
Packit |
85355f |
an integer number, with the first directory numbered
|
|
Packit |
85355f |
zero.
|
|
Packit |
85355f |
|
|
Packit |
85355f |
TIFFSetSubDirectory acts like
|
|
Packit |
85355f |
TIFFSetDirectory, except the directory is specified
|
|
Packit |
85355f |
as a file offset instead of an index; this is required for
|
|
Packit |
85355f |
accessing subdirectories linked through a SubIFD
|
|
Packit |
85355f |
tag.
