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

SYNOPSIS
       #include <tiffio.h>

       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 reasonable-sized strip according  to
       the  current settings of the ImageWidth, BitsPerSample, SamplesPerPixel, tags and any com-
       pression-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 compression-spe-
       cific 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  TIFFReadEncodedStrip  or  as it would be expected in a call to TIFFWriteEncoded-
       Strip.

       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 specified 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.
