20 TIFFDefaultStripSize returns the number of rows for a reasonable-sized
21 strip according to the current settings of the ImageWidth, BitsPerSam‐
22 ple, SamplesPerPixel, tags and any compression-specific requirements.
23 If the estimate parameter, if non-zero, then it is taken as an estimate
24 of the desired strip size and adjusted according to any compression-
25 specific requirements. The value returned by this function is typically
26 used to define the RowsPerStrip tag. In lieu of any unusual require‐
27 ments TIFFDefaultStripSize tries to create strips that have approxi‐
28 mately 8 kilobytes of uncompressed data.
29
30 TIFFStripSize returns the equivalent size for a strip of data as it
31 would be returned in a call to TIFFReadEncodedStrip or as it would be
32 expected in a call to TIFFWriteEncodedStrip.
33
34 TIFFVStripSize returns the number of bytes in a strip with nrows rows
35 of data.
36
37 TIFFRawStripSize returns the number of bytes in a raw strip (i.e. not
38 decoded).
39
40 TIFFComputeStrip returns the strip that contains the specified coordi‐
41 nates. A valid strip is always returned; out-of-range coordinate values
42 are clamped to the bounds of the image. The row parameter is always
43 used in calculating a strip. The sample parameter is used only if data
44 are organized in separate planes (PlanarConfiguration=2).
45
46 TIFFNumberOfStrips returns the number of strips in the image.
47
49 None.
