| | 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> |
