## Synopsis

    #include <tiffio.h>

tmsize_t TIFFRasterScanlineSize(TIFF *tif)

uint64_t TIFFRasterScanlineSize64(TIFF *tif)

tmsize_t TIFFScanlineSize(TIFF *tif)

uint64_t TIFFScanlineSize64(TIFF *tif)

## Description

`TIFFScanlineSize()` returns the size in bytes of a row of data as it would be returned in a call to `TIFFReadScanline()`, or as it would be expected in a call to `TIFFWriteScanline()`. Note that this number may be 1/samples-per-pixel if data is stored as separate planes. The ScanlineSize in case of YCbCrSubsampling is defined as the strip size divided by the strip height, i.e. the size of a pack of vertical subsampling lines divided by vertical subsampling. It should thus make sense when multiplied by a multiple of vertical subsampling. `TIFFScanlineSize64()` returns the size as `uint64_t`.

`TIFFRasterScanlineSize()` returns the size in bytes of a complete decoded and packed raster scanline. Note that this value may be different from the value returned by `TIFFScanlineSize()` if data is stored as separate planes. `TIFFRasterScanlineSize64()` returns the size as `uint64_t`.

## Diagnostics

None.
