| 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

| 81 | <!-- INDENTATION -->
|

| 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
|

|

| 104 | organized in separate planes.</p>
