TIFFReadRawStrip(3tiff) 				 Introduction to Library Functions				   TIFFReadRawStrip(3tiff)

NAME
TIFFReadRawStrip - return the undecoded contents of a strip of data from an open TIFF file SYNOPSIS
#include <tiffio.h> tsize_t TIFFReadRawStrip(TIFF* tif, tstrip_t strip, tdata_t buf, tsize_t size) DESCRIPTION
Read the contents of the specified strip into the user supplied data buffer. Note that the value of strip is a "raw strip number". That is, the caller must take into account whether or not the data is organized in separate planes (PlanarConfiguration=2). To read a full strip of data, the data buffer should typically be at least as large as the value returned by TIFFStripSize. All error messages are directed to the TIFFError(3tiff) routine. RETURN VALUES
Returns the actual number of bytes of data that were placed in buf. Returns -1 if an error was encountered. ATTRIBUTES

NAME
TIFFstrip, TIFFDefaultStripSize, TIFFStripSize, TIFFVStripSize, 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) 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, BitsPer- Sample, and SamplesPerPixel tags, and any compression-specific requirements. If the estimate parameter is 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. TIFFComputeStrip returns the strip that contains the specified coordinates. A valid strip is always returned. Out-of-range coordinate val- ues 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 is organized in separate planes (PlanarConfiguration=2). TIFFNumberOfStrips returns the number of strips in the image. ATTRIBUTES
