TIFFstrip(3)





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, BitsPerSam-
       ple, 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  require-
       ments  TIFFDefaultStripSize  tries  to create strips that have approxi-
       mately 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.

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

       TIFFComputeStrip returns the strip that contains the specified  coordi-
       nates. 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.
