TIFFSTRIP(3TIFF)                                 TIFFSTRIP(3TIFF)



NAME
       TIFFDefaultStripSize,    TIFFStripSize,    TIFFVStripSize,
       TIFFRawStripSize, TIFFComputeStrip,  TIFFNumberOfStrips  -
       strip-related utility routines

SYNOPSIS
       #include 

       uint32 TIFFDefaultStripSize(TIFF *tif, uint32 estimate)
       tsize_t TIFFStripSize(TIFF *tif)
       tsize_t TIFFVStripSize(TIFF *tif, uint32 nrows)
       tsize_t TIFFRawStripSize(TIFF *tif, tstrip_t strip)
       tstrip_t TIFFComputeStrip(TIFF *tif, uint32 row, tsample_t
       sample)
       tstrip_t TIFFNumberOfStrips(TIFF *tif)

DESCRIPTION
       TIFFDefaultStripSize returns the number of rows for a rea-
       sonable-sized  strip  according to the current settings of
       the ImageWidth, BitsPerSample, SamplesPerPixel,  tags  and
       any  compression-specific  requirements.  If  the estimate
       parameter, if non-zero, then it is taken as an estimate of
       the  desired strip size and adjusted according to any com-
       pression-specific requirements. The value returned by this
       function is typically used to define the RowsPerStrip tag.
       In lieu of any unusual  requirements  TIFFDefaultStripSize
       tries to create strips that have approximately 8 kilobytes
       of uncompressed data.

       TIFFStripSize returns the equivalent size for a  strip  of
       data as it would be returned in a call to TIFFReadEncoded-
       Strip or as it would be expected in a call to TIFFWriteEn-
       codedStrip.

       TIFFVStripSize returns the number of bytes in a strip with
       nrows rows of data.

       TIFFRawStripSize returns the number  of  bytes  in  a  raw
       strip (i.e. not decoded).

       TIFFComputeStrip returns the strip that contains the spec-
       ified coordinates. A valid strip is always returned;  out-
       of-range  coordinate  values  are clamped to the bounds of
       the image. The row parameter is always used in calculating
       a  strip.  The  sample  parameter is used only if data are
       organized in separate planes (PlanarConfiguration=2).

       TIFFNumberOfStrips returns the number  of  strips  in  the
       image.

DIAGNOSTICS
       None.
