NAME


TIFFDeferStrileArrayWriting - defer strile array writing

SYNOPSIS



#include <tiffio.h>

int TIFFDeferStrileArrayWriting(TIFF *tif)

int TIFFForceStrileArrayWriting(TIFF *tif)

DESCRIPTION


TIFFDeferStrileArrayWriting() is an advanced writing function that
must be used in a particular sequence, and generally together with
TIFFForceStrileArrayWriting(), to achieve its intended effect. Their
aim is to control when and where the StripOffsets / StripByteCounts
or TileOffsets / TileByteCounts arrays are written into the file.

The purpose of this is to generate 'cloud-optimized geotiff' files
where the first KB of the file only contain the IFD entries without
the potentially large strile arrays. Those are written afterwards.

More precisely, when TIFFWriteCheck() is called, the tag entries for
those arrays will be written with type = count = offset = 0 as a
temporary value.

Its effect is only valid for the current directory, and before
TIFFWriteDirectory() is first called, and will be reset when
changing directory.

The typical sequence of calls is:

TIFFOpen()
/* or TIFFCreateDirectory(tif) */
/* Set fields with calls to TIFFSetField(tif, ...) */
TIFFDeferStrileArrayWriting(tif)
TIFFWriteCheck(tif, ...)
TIFFWriteDirectory(tif)
/* ... potentially create other directories and come back to the above directory */
TIFFForceStrileArrayWriting(tif) /* emit the arrays at the end of file */

RETURNS


1 in case of success, 0 otherwise.

DIAGNOSTICS


All error messages are directed to the TIFFErrorExtR() routine.
Likewise, warning messages are directed to the TIFFWarningExtR()
routine.

NOTE


This functionality was introduced with libtiff 4.1.
