TIFFSTRIP(3T)	  Image	Format Library C++ Reference Manual	 TIFFSTRIP(3T)

NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

     #include <tiffio.h>
     uint32 TIFFDefaultStripSize(TIFF* tif, uint32 estimate)
     tsize_t TIFFStripSize(TIFF* tif)
     tsize_t TIFFVStripSize(TIFF* tif, uint32 nrows)
     tstrip_t TIFFComputeStrip(TIFF* tif, uint32 row, tsample_t	sample)
     tstrip_t TIFFNumberOfStrips(TIFF* tif)

DESCRIPTION    [Toc]    [Back]

     TIFFDefaultStripSize returns the number of	rows for a reasonable-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 compression-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 TIFFReadEncodedStrip or as it would be expected
     in	a call to TIFFWriteEncodedStrip.

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

     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    [Toc]    [Back]

     None.
