TIFFReadFromUserBuffer — LibTIFF 4.7.1 documentation

# TIFFReadFromUserBuffer

## 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.
