TIFFREADFROMUSERBUFFER(3tiff)

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.
