TIFFBUFFER(3T) Image Format Library C++ Reference Manual TIFFBUFFER(3T)
TIFFReadBufferSetup, TIFFWriteBufferSetup - I/O buffering control
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; they
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 and zero otherwise.
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
and zero otherwise.
%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.
