If the <i>tw</i> and <i>th</i> values passed in are non-zero, then they are adjusted to reflect any compression-specific requirements. The returned width and height are constrained to be a multiple of 16 pixels to conform with the <small>TIFF</small> specification.</p> <!-- INDENTATION --> <p><i>TIFFTileSize</i> returns the equivalent size for a tile of data as it would be returned in a call to <i>TIFFReadTile</i> or as it would be expected in a call to <i>TIFFWriteTile</i>.</p> <!-- INDENTATION --> <p><i>TIFFVTileSize</i> returns the number of bytes in a row-aligned tile with <i>nrows</i> of data.</p> <!-- INDENTATION --> <p><i>TIFFTileRowSize</i> returns the number of bytes of a row of data in a tile.</p> <!-- INDENTATION --> <p><i>TIFFComputeTile</i> returns the tile that contains the specified coordinates. A valid tile is always returned; out-of-range coordinate values are clamped to the bounds of the image. The <i>x</i> and <i>y</i> parameters are always used in calculating a tile. The <i>z</i> parameter is used if the image is deeper than 1 slice (<i>ImageDepth</i>>1). The <i>sample</i> parameter is used only if data are organized in separate planes (<i>PlanarConfiguration</i>=2).</p> <!-- INDENTATION --> <p><i>TIFFCheckTile</i> returns a non-zero value if the supplied coordinates are within the bounds of the image and zero otherwise. The <i>x</i> parameter is checked against the value of the <i>ImageWidth</i> tag. The <i>y</i> parameter is checked against the value of the <i>ImageLength</i> tag. The <i>z</i> parameter is checked against the value of the <i>ImageDepth</i> tag (if defined). The <i>sample</i> parameter is checked against the value of the <i>SamplesPerPixel</i> parameter if the data are organized in separate planes.</p> <!-- INDENTATION --> <p><i>TIFFNumberOfTiles</i> returns the number of tiles in the image.</p> </td> </table> <a name="DIAGNOSTICS"></a> <h2>DIAGNOSTICS</h2> <!-- INDENTATION --> <table width="100%" border=0 rules="none" frame="void" cols="2" cellspacing="0" cellpadding="0"> <tr valign="top" align="left"> <td width="8%"></td> <td width="91%"> <p>None.</p> </td> </table> <a name="SEE ALSO"></a> <h2>SEE ALSO</h2> <!-- INDENTATION --> <table width="100%" border=0 rules="none" frame="void" cols="2" cellspacing="0" cellpadding="0"> <tr valign="top" align="left"> <td width="8%"></td> <td width="91%"> <p><b>TIFFReadEncodedTile</b>(3TIFF), <b>TIFFReadRawTile</b>(3TIFF), <b>TIFFReadTile</b>(3TIFF), <b>TIFFWriteEncodedTile</b>(3TIFF), <b>TIFFWriteRawTile</b>(3TIFF), <b>TIFFWriteTile</b>(3TIFF), <b>libtiff</b>(3TIFF)</p> <!-- INDENTATION --> <p>Libtiff library home page: <b>http://www.remotesensing.org/libtiff/</b></p> </td> </table> <hr> </body> </html>
