<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> |
