| 67 | <p>The following routines return status information about an
|
|---|
| 68 | open <small>TIFF</small> file.</p>
|
|---|
| 69 | <!-- INDENTATION -->
|
|---|
| 70 | <p><i>TIFFCurrentDirectory</i> returns the index of the
|
|---|
| 71 | current directory (directories are numbered starting at 0).
|
|---|
| 72 | This number is suitable for use with the
|
|---|
| 73 | <i>TIFFSetDirectory</i> routine.</p>
|
|---|
| 74 | <!-- INDENTATION -->
|
|---|
| 75 | <p><i>TIFFLastDirectory</i> returns a non-zero value if the
|
|---|
| 76 | current directory is the last directory in the file;
|
|---|
| 77 | otherwise zero is returned.</p>
|
|---|
| 78 | <!-- INDENTATION -->
|
|---|
| 79 | <p><i>TIFFCurrentRow</i>, <i>TIFFCurrentStrip</i>, and
|
|---|
| 80 | <i>TIFFCurrentTile</i>, return the current row, strip, and
|
|---|
| 81 | tile, respectively, that is being read or written. These
|
|---|
| 82 | values are updated each time a read or write is done.</p>
|
|---|
| 83 | <!-- INDENTATION -->
|
|---|
| 84 | <p><i>TIFFFileno</i> returns the underlying file descriptor
|
|---|
| 85 | used to access the <small>TIFF</small> image in the
|
|---|
| 86 | filesystem.</p>
|
|---|
| 87 | <!-- INDENTATION -->
|
|---|
| 88 | <p><i>TIFFFileName</i> returns the pathname argument passed
|
|---|
| 89 | to <i>TIFFOpen</i> or <i>TIFFFdOpen</i>.</p>
|
|---|
| 90 | <!-- INDENTATION -->
|
|---|
| 91 | <p><i>TIFFGetMode</i> returns the mode with which the
|
|---|
| 92 | underlying file was opened. On <small>UNIX</small> systems,
|
|---|
| 93 | this is the value passed to the <i>open</i>(2) system
|
|---|
| 94 | call.</p>
|
|---|
| 95 | <!-- INDENTATION -->
|
|---|
| 96 | <p><i>TIFFIsTiled</i> returns a non-zero value if the image
|
|---|
| 97 | data has a tiled organization. Zero is returned if the image
|
|---|
| 98 | data is organized in strips.</p>
|
|---|
| 99 | <!-- INDENTATION -->
|
|---|
| 100 | <p><i>TIFFIsByteSwapped</i> returns a non-zero value if the
|
|---|
| 101 | image data was in a different byte-order than the host
|
|---|
| 102 | machine. Zero is returned if the TIFF file and local host
|
|---|
| 103 | byte-orders are the same. Note that TIFFReadTile(),
|
|---|
| 104 | TIFFReadStrip() and TIFFReadScanline() functions already
|
|---|
| 105 | normally perform byte swapping to local host order if
|
|---|
| 106 | needed.</p>
|
|---|
| 107 | <!-- INDENTATION -->
|
|---|
| 108 | <p><i>TIFFIsUpSampled</i> returns a non-zero value if image
|
|---|
| 109 | data returned through the read interface routines is being
|
|---|
| 110 | up-sampled. This can be useful to applications that want to
|
|---|
| 111 | calculate I/O buffer sizes to reflect this usage (though the
|
|---|
| 112 | usual strip and tile size routines already do this).</p>
|
|---|
| 113 | <!-- INDENTATION -->
|
|---|
| 114 | <p><i>TIFFIsMSB2LSB</i> returns a non-zero value if the
|
|---|
| 115 | image data is being returned with bit 0 as the most
|
|---|
| 116 | significant bit.</p>
|
|---|
| 117 | <!-- INDENTATION -->
|
|---|
| 118 | <p><i>TIFFGetVersion</i> returns an <small>ASCII</small>
|
|---|
| 119 | string that has a version stamp for the <small>TIFF</small>
|
|---|
| 120 | library software.</p>
