# TIFFReadFromUserBuffer(3tiff)

decode data using an user defined buffer

## NAME

TIFFReadFromUserBuffer - decode data using an user defined buffer

## SYNOPSIS

```
#include <tiffio.h>
```

- **int TIFFReadFromUserBuffer(TIFF \*tif, uint32\_t strile, void \*inbuf, tmsize\_t insize, void \*outbuf, tmsize\_t outsize)**

  ## DESCRIPTION

Use the provided input buffer (*inbuf*, *insize*) and decompress it into (*outbuf*, *outsize*). This function replaces the use of *TIFFReadEncodedStrip()* / *TIFFReadEncodedTile()* when the user can provide the buffer for the input data, for example when he wants to avoid **libtiff** to read the strile offset/count values from the **StripOffsets** / **StripByteCounts** or **TileOffsets** / **TileByteCounts** arrays. *inbuf* content must be writable (if bit reversal is needed).

## RETURN VALUES

Returns 1 in case of success, 0 otherwise.

## DIAGNOSTICS

All error messages are directed to the *TIFFErrorExtR()* routine.
