|
|
<p><i>TIFFDefaultTileSize</i> returns the pixel width and
|
|
height of a reasonable-sized tile; suitable for setting up
|
|
the <i>TileWidth</i> and <i>TileLength</i> tags. 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>
