.SH NAME
TIFFReadFromUserBuffer \- decode data using an user defined buffer
.SH SYNOPSIS
.INDENT 0.0
.INDENT 3.5
.sp
.EX
#include <tiffio.h>

.B int TIFFReadFromUserBuffer(TIFF *tif, uint32_t strile, void *inbuf, tmsize_t insize, void *outbuf, tmsize_t outsize) 
.UNINDENT
.SH DESCRIPTION
.sp
Use the provided input buffer (\fIinbuf\fP, \fIinsize\fP) and decompress it
into (\fIoutbuf\fP, \fIoutsize\fP). This function replaces the use of
\fI\%TIFFReadEncodedStrip()\fP / \fI\%TIFFReadEncodedTile()\fP
when the user can provide the buffer for the input data, for example when
he wants to avoid \fBlibtiff\fP to read the strile offset/count values from the
\fBStripOffsets\fP / \fBStripByteCounts\fP or \fBTileOffsets\fP /
\fBTileByteCounts\fP arrays. \fIinbuf\fP content must be writable
(if bit reversal is needed).
.SH RETURN VALUES
.sp
Returns 1 in case of success, 0 otherwise.
.SH DIAGNOSTICS
.sp
All error messages are directed to the \fI\%TIFFErrorExtR()\fP routine.
