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.

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);

DESCRIPTION

       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.

EXTENDED DESCRIPTION

       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.
