TIFFWriteDirectory will write the contents of the
|
|
Packit |
85355f |
current directory to the file and setup to create a new
|
|
Packit |
85355f |
subfile in the same file. Applications only need to call
|
|
Packit |
85355f |
TIFFWriteDirectory when writing multiple subfiles to
|
|
Packit |
85355f |
a single <small>TIFF</small> file. TIFFWriteDirectory
|
|
Packit |
85355f |
is automatically called by TIFFClose and
|
|
Packit |
85355f |
TIFFFlush to write a modified directory if the file
|
|
Packit |
85355f |
is open for writing.
|
|
Packit |
85355f |
|
|
Packit |
85355f |
The TIFFRewriteDirectory function operates
|
|
Packit |
85355f |
similarly to TIFFWriteDirectory, but can be called
|
|
Packit |
85355f |
with directories previously read or written that already
|
|
Packit |
85355f |
have an established location in the file. It will rewrite
|
|
Packit |
85355f |
the directory, but instead of place it at it’s old
|
|
Packit |
85355f |
location (as TIFFWriteDirectory would) it will place
|
|
Packit |
85355f |
them at the end of the file, correcting the pointer from the
|
|
Packit |
85355f |
preceeding directory or file header to point to it’s
|
|
Packit |
85355f |
new location. This is particularly important in cases where
|
|
Packit |
85355f |
the size of the directory and pointed to data has grown, so
|
|
Packit |
85355f |
it won’t fit in the space available at the old
|
|
Packit |
85355f |
location.
|
|
Packit |
85355f |
|
|
Packit |
85355f |
The TIFFCheckpointDirectory writes the current
|
|
Packit |
85355f |
state of the tiff directory into the file to make what is
|
|
Packit |
85355f |
currently in the file readable. Unlike
|
|
Packit |
85355f |
TIFFWriteDirectory, TIFFCheckpointDirectory does not
|
|
Packit |
85355f |
free up the directory data structures in memory, so they can
|
|
Packit |
85355f |
be updated (as strips/tiles are written) and written again.
|
|
Packit |
85355f |
Reading such a partial file you will at worst get a tiff
|
|
Packit |
85355f |
read error for the first strip/tile encountered that is
|
|
Packit |
85355f |
incomplete, but you will at least get all the valid data in
|
|
Packit |
85355f |
the file before that. When the file is complete, just use
|
|
Packit |
85355f |
TIFFWriteDirectory as usual to finish it off
|
|
Packit |
85355f |
cleanly.
