NAME TIFFtile - tile-related utility routines
SYNOPSIS
#include <tiffio.h>
void TIFFDefaultTileSize(TIFF *tif, uint32_t *tw, uint32_t *th)
tsize_t TIFFTileSize(TIFF *tif)
uint64_t TIFFTileSize64(TIFF *tif)
tsize_t TIFFTileRowSize(TIFF *tif)
uint64_t TIFFTileRowSize64(TIFF *tif)
tsize_t TIFFVTileSize(TIFF *tif, uint32_t nrows)
uint64_t TIFFVTileSize64(TIFF *tif, uint32_t nrows)
ttile_t TIFFComputeTile(TIFF *tif, uint32_t x, uint32_t y, uint32_t z, tsample_t sample)
int TIFFCheckTile(TIFF *tif, uint32_t x, uint32_t y, uint32_t z, tsample_t sample)
ttile_t TIFFNumberOfTiles(TIFF *tif)
DESCRIPTION TIFFDefaultTileSize() returns the pixel width and height of a reasonable-sized tile; suitable for setting up the TileWidth and TileLength tags. If the tw and th 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 TIFF specification.
TIFFTileSize() returns the equivalent size for a tile of data as it would be returned in a call to TIFFReadTile() or as it would be expected in a call to TIFFWriteTile(). TIFFTileSize64() returns a uint64_t number. If an error occurs, 0 is returned.
TIFFVTileSize() returns the number of bytes in a row-aligned tile with nrows of data. TIFFVTileSize64() returns a uint64_t number. If an error occurs, 0 is returned.
TIFFTileRowSize() returns the number of bytes of a row of data in a tile. TIFFTileRowSize64() returns a uint64_t number. If an error occurs, 0 is returned.
TIFFComputeTile() 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 x and y parameters are always used in calculating a tile. The z parameter is used if the image is deeper than 1 slice (ImageDepth > 1). The sample parameter is used only if data are organized in separate planes (PlanarConfiguration = 2). parameter if the data are organized in separate planes.
TIFFNumberOfTiles() returns the number of tiles in the image.
DIAGNOSTICS None.
