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.
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.

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 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.
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

TIFFNumberOfStrips returns the number of strips in the image.
