Description¶
TIFFDefaultStripSize() returns the number of rows for a
reasonable-sized strip according to the current settings of the
ImageWidth, BitsPerSample and SamplesPerPixel,
tags and any compression-specific requirements. If the estimate
parameter, sf 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().
If an error occurs, 0 is returned.
TIFFStripSize64() returns the equivalent size for a strip of data
as uint64_t.
If an error occurs, 0 is returned.
TIFFVStripSize() returns the number of bytes in a strip with
nrows rows of data.
If an error occurs, 0 is returned.
TIFFVStripSize64() returns the number of bytes in a strip with
nrows rows of data as uint64_t.
If an error occurs, 0 is returned.
TIFFRawStripSize() returns the number of bytes in a raw strip
(i.e. not decoded).
If an error occurs, 0xFFFFFFFF (=(tmsize_t(-1)) is returned.
TIFFRawStripSize64() returns the number of bytes in a raw strip
as uint64_t.
If an error occurs, 0xFFFFFFFF (=(uint64_t(-1)) is returned.
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.
TIFFSetupStrips() setup or reset strip parameters and strip array memory.
Diagnostics¶
None.
