DESCRIPTION

+ + + + + +
+

The following routines return status information about an +open TIFF file.

+ +

TIFFCurrentDirectory returns the index of the +current directory (directories are numbered starting at 0). +This number is suitable for use with the +TIFFSetDirectory routine.

+ +

TIFFLastDirectory returns a non-zero value if the +current directory is the last directory in the file; +otherwise zero is returned.

+ +

TIFFCurrentRow, TIFFCurrentStrip, and +TIFFCurrentTile, return the current row, strip, and +tile, respectively, that is being read or written. These +values are updated each time a read or write is done.

+ +

TIFFFileno returns the underlying file descriptor +used to access the TIFF image in the +filesystem.

+ +

TIFFFileName returns the pathname argument passed +to TIFFOpen or TIFFFdOpen.

+ +

TIFFGetMode returns the mode with which the +underlying file was opened. On UNIX systems, +this is the value passed to the open(2) system +call.

+ +

TIFFIsTiled returns a non-zero value if the image +data has a tiled organization. Zero is returned if the image +data is organized in strips.

+ +

TIFFIsByteSwapped returns a non-zero value if the +image data was in a different byte-order than the host +machine. Zero is returned if the TIFF file and local host +byte-orders are the same. Note that TIFFReadTile(), +TIFFReadStrip() and TIFFReadScanline() functions already +normally perform byte swapping to local host order if +needed.

+ +

TIFFIsUpSampled returns a non-zero value if image +data returned through the read interface routines is being +up-sampled. This can be useful to applications that want to +calculate I/O buffer sizes to reflect this usage (though the +usual strip and tile size routines already do this).

+ +

TIFFIsMSB2LSB returns a non-zero value if the +image data is being returned with bit 0 as the most +significant bit.

+ +

TIFFGetVersion returns an ASCII +string that has a version stamp for the TIFF +library software.

+
+ +
