|
65 <p><i>TIFFDefaultTileSize</i> returns the pixel width and |
|
66 height of a reasonable-sized tile; suitable for setting up |
|
67 the <i>TileWidth</i> and <i>TileLength</i> tags. If the |
|
68 <i>tw</i> and <i>th</i> values passed in are non-zero, then |
|
69 they are adjusted to reflect any compression-specific |
|
70 requirements. The returned width and height are constrained |
|
71 to be a multiple of 16 pixels to conform with the |
|
72 <small>TIFF</small> specification.</p> |
|
73 <!-- INDENTATION --> |
|
74 <p><i>TIFFTileSize</i> returns the equivalent size for a |
|
75 tile of data as it would be returned in a call to |
|
76 <i>TIFFReadTile</i> or as it would be expected in a call to |
|
77 <i>TIFFWriteTile</i>.</p> |
|
78 <!-- INDENTATION --> |
|
79 <p><i>TIFFVTileSize</i> returns the number of bytes in a |
|
80 row-aligned tile with <i>nrows</i> of data.</p> |
|
81 <!-- INDENTATION --> |
|
82 <p><i>TIFFTileRowSize</i> returns the number of bytes of a |
|
83 row of data in a tile.</p> |
|
84 <!-- INDENTATION --> |
|
85 <p><i>TIFFComputeTile</i> returns the tile that contains the |
|
86 specified coordinates. A valid tile is always returned; |
|
87 out-of-range coordinate values are clamped to the bounds of |
|
88 the image. The <i>x</i> and <i>y</i> parameters are always |
|
89 used in calculating a tile. The <i>z</i> parameter is used |
|
90 if the image is deeper than 1 slice |
|
91 (<i>ImageDepth</i>>1). The <i>sample</i> parameter is |
|
92 used only if data are organized in separate planes |
|
93 (<i>PlanarConfiguration</i>=2).</p> |
|
94 <!-- INDENTATION --> |
|
95 <p><i>TIFFCheckTile</i> returns a non-zero value if the |
|
96 supplied coordinates are within the bounds of the image and |
|
97 zero otherwise. The <i>x</i> parameter is checked against |
|
98 the value of the <i>ImageWidth</i> tag. The <i>y</i> |
|
99 parameter is checked against the value of the |
|
100 <i>ImageLength</i> tag. The <i>z</i> parameter is checked |
|
101 against the value of the <i>ImageDepth</i> tag (if defined). |
|
102 The <i>sample</i> parameter is checked against the value of |
|
103 the <i>SamplesPerPixel</i> parameter if the data are |
|
104 organized in separate planes.</p> |
|
105 <!-- INDENTATION --> |
|
106 <p><i>TIFFNumberOfTiles</i> returns the number of tiles in |
|
107 the image.</p> |
