NAME
TIFFbuffer, TIFFReadBufferSetup, TIFFWriteBufferSetup - I/O buffering control routines
SYNOPSIS
#include <tiffio.h>
int TIFFReadBufferSetup(TIFF*, tdata_t buffer, tsize_t size);
int TIFFWriteBufferSetup(TIFF*, tdata_t buffer, tsize_t size);
The following routines are provided for client-control of the I/O buffers used by the library. Applications need never use these routines.
The routines are provided only for "intelligent clients" that wish to optimize memory usage and/or eliminate potential copy operations that
can occur when working with images that have data stored without compression.
TIFFReadBufferSetup sets up the data buffer used to read raw (encoded) data from a file. If the specified pointer is NULL (zero), then a
buffer of the appropriate size is allocated. Otherwise, the caller must guarantee that the buffer is large enough to hold any individual
strip of raw data. TIFFReadBufferSetup returns a non-zero value if the setup was successful.
TIFFWriteBufferSetup sets up the data buffer used to write raw (encoded) data to a file. If the specified size is -1 then the buffer size
is selected to hold a complete tile or strip, or at least 8 kilobytes, whichever is greater. If the specified buffer is NULL (zero), then a
buffer of the appropriate size is dynamically allocated. TIFFWriteBufferSetup returns a non-zero value if the setup was successful.
Diagnostics
%s: No space for data buffer at scanline %ld.
TIFFReadBufferSetup was unable to dynamically allocate space for a data buffer.
%s: No space for output buffer.
TIFFWriteBufferSetup was unable to dynamically allocate space for a data buffer.
