.SH DESCRIPTION
|
|
|
|
|
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.
|
|
|
|
|
.PP
|
|
|
|
|
.I TIFFReadBufferSetup
|
|
|
|
|
sets up the data buffer used to read raw (encoded) data from a file. If the
|
|
|
|
|
specified pointer is
|
|
|
|
|
.SM 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.
|
|
|
|
|
.I TIFFReadBufferSetup
|
|
|
|
|
returns a non-zero value if the setup was successful and zero otherwise.
|
|
|
|
|
.PP
|
|
|
|
|
.I TIFFWriteBufferSetup
|
|
|
|
|
sets up the data buffer used to write raw (encoded) data to a file. If the
|
|
|
|
|
specified
|
|
|
|
|
.I 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
|
|
|
|
|
.I buffer
|
|
|
|
|
is
|
|
|
|
|
.SM NULL
|
|
|
|
|
(zero), then a buffer of the appropriate size is dynamically allocated.
|
|
|
|
|
.I TIFFWriteBufferSetup
|
|
|
|
|
returns a non-zero value if the setup was successful and zero otherwise.
|
|
|
|
|
.SH DIAGNOSTICS
