The buffer must be large enough -to hold an entire scanline of data. Applications should call the routine -.IR TIFFScanlineSize -to find out the size (in bytes) of a scanline buffer. -The -.I row -parameter is always used by -.IR TIFFReadScanline ; -the -.I sample -parameter is used only if data are organized in separate planes (\c -.IR PlanarConfiguration =2). -.SH NOTES -The library attempts to hide bit- and byte-ordering differences between the -image and the native machine by converting data to the native machine order. -Bit reversal is done if the -.I FillOrder -tag is opposite to the native machine bit order. 16- and 32-bit samples are -automatically byte-swapped if the file was written with a byte order opposite -to the native machine byte order, -.PP -In C++ the -.I sample -parameter defaults to 0. -.SH "RETURN VALUES" -.IR TIFFReadScanline -returns \-1 if it detects an error; otherwise 1 is returned. -.SH DIAGNOSTICS -All error messages are directed to the -.IR TIFFError (3TIFF) -routine. -.PP -.BR "Compression algorithm does not support random access" . -Data was requested in a non-sequential order from a file that uses a -compression algorithm and that has -.I RowsPerStrip -greater than one. -That is, data in the image is stored in a compressed form, and with multiple -rows packed into a strip. In this case, the library does not support random -access to the data. The data should either be accessed sequentially, or the -file should be converted so that each strip is made up of one row of data. -.SH BUGS -Reading subsampled YCbCR data does not work correctly because, for -.IR PlanarConfiguration =2 -the size of a scanline is not calculated on a per-sample basis, and for -.IR PlanarConfiguration =1 -the library does not unpack the block-interleaved samples; use the strip- and -tile-based interfaces to read these formats. -.SH "SEE ALSO" -.BR TIFFOpen (3TIFF), -.BR TIFFReadEncodedStrip (3TIFF), -.BR TIFFReadRawStrip (3TIFF), -.BR libtiff (3TIFF) -.PP -Libtiff library home page: -.BR http://www.remotesensing.org/libtiff/ |
