DESCRIPTION

       cols="2" cellspacing="0" cellpadding="0">

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.
