tiffwritedirectory
TIFFWriteDirectory(3T)TIFFWriteDirectory(3T)NAME
TIFFWriteDirectory, TIFFRewriteDirectory - write the current directory in an open TIFF file
SYNOPSIS
#include <tiffio.h>
int TIFFWriteDirectory(TIFF* tif)
int TIFFRewriteDirectory(TIFF* tif)
DESCRIPTION
TIFFWriteDirectory will write the contents of the current directory to the file and setup to create a new subfile in the same file. Appli-
cations only need to call TIFFWriteDirectory when writing multiple subfiles to a single TIFF file. TIFFWriteDirectory is automatically
called by TIFFClose and TIFFFlush to write a modified directory if the file is open for writing.
The TIFFRewriteDirectory function operates similarly to TIFFWriteDirectory but can be called with directories previously read or written
that already have an established location in the file. It will rewrite the directory, but instead of place it at it's old location (as
TIFFWriteDirectory would) it will place them at the end of the file, correcting the pointer from the preceeding directory or file header to
point to it's new location. This is particularly important in cases where the size of the directory and pointed to data has grown, so it
won't fit in the space available at the old location.
RETURN VALUES
1 is returned when the contents are successfully written to the file. Otherwise, 0 is returned if an error was encountered when writing
the directory contents.
DIAGNOSTICS
All error messages are directed to the TIFFError(3T) routine.
Error post-encoding before directory write. Before writing the contents of the current directory, any pending data are flushed. This mes-
sage indicates that an error occurred while doing this.
Error flushing data before directory write. Before writing the contents of the current directory, any pending data are flushed. This mes-
sage indicates that an error occurred while doing this.
Cannot write directory, out of space. There was not enough space to allocate a temporary area for the directory that was to be written.
Error writing directory count. A write error occurred when writing the count of fields in the directory.
Error writing directory contents. A write error occurred when writing the directory fields.
Error writing directory link. A write error occurred when writing the link to the next directory.
Error writing data for field "%s". A write error occurred when writing indirect data for the specified field.
Error writing TIFF header. A write error occurred when re-writing header at the front of the file.
Error fetching directory count. A read error occurred when fetching the directory count field for a previous directory. This can occur
when setting up a link to the directory that is being written.
Error fetching directory link. A read error occurred when fetching the directory link field for a previous directory. This can occur when
setting up a link to the directory that is being written.
