10139N/A<para><literal>TIFFDefaultTileSize</literal> returns the pixel width and height

10139N/Aof a reasonable-sized tile, suitable for setting up the <literal>TileWidth

10139N/A</literal> and <literal>TileLength</literal> tags. If the <replaceable>tw

10139N/A</replaceable> and <replaceable>th</replaceable> values passed in are non-zero,

10139N/Athen they are adjusted to reflect any compression-specific requirements. The

10139N/Areturned width and height are constrained to be a multiple of 16 pixels, to

10139N/Aconform with the TIFF specification.</para>

10139N/A<para><literal>TIFFTileSize</literal> returns the equivalent size for a tile

10139N/Aof data as it would be returned in a call to <literal>TIFFReadTile</literal>

10139N/Aor as it would be expected in a call to <literal>TIFFWriteTile</literal>.

10139N/A</para>

10139N/A<para><literal>TIFFVTileSize</literal> returns the number of bytes in a row-aligned

10139N/Atile with <literal>nrows</literal> of data.</para>

10139N/A<para><literal>TIFFTileRowSize</literal> returns the number of bytes of a

10139N/Arow of data in a tile.</para>

10139N/A<para><literal>TIFFComputeTile</literal> returns the tile that contains the

10139N/Aspecified coordinates. A valid tile is always returned. Out-of-range coordinate

10139N/Avalues are clamped to the bounds of the image. The <literal>x</literal> and <literal>

10139N/Ay</literal> parameters are always used in calculating a tile. The <literal>

10139N/Az</literal> parameter is used if the image is deeper than 1 slice (ImageDepth>1).

10139N/AThe <literal>sample</literal> parameter is used only if data is organized

10139N/Ain separate planes (PlanarConfiguration=2).</para>

10139N/A<para><literal>TIFFCheckTile</literal> returns a non-zero value if the supplied

10139N/Acoordinates are within the bounds of the image, and zero otherwise. The <literal>

10139N/Ax</literal> parameter is checked against the value of the ImageWidth tag.

10139N/AThe <literal>y</literal> parameter is checked against the value of the <literal>

10139N/AImageLength</literal> tag. The <literal>z</literal> parameter is checked against

10139N/Athe value of the <literal>ImageDepth</literal> tag (if defined). The <literal>

10139N/Asample</literal> parameter is checked against the value of the <literal>SamplesPerPixel

10139N/A</literal> parameter if the data is organized in separate planes.</para>

10139N/A<para><literal>TIFFNumberOfTiles</literal> returns the number of tiles in

10139N/Athe image.</para>
