Description

Used in Raw IFD of DNG files.

Normally, the pixels within a tile are stored in simple row-scan order. This tag specifies that the pixels within a tile should be grouped first into rectangular blocks of the specified size. The first value is the number of rows and is named SubTileBlockRows, the second value is the number of columns and is named SubTileBlockCols.

These blocks are stored in row-scan order. Within each block, the pixels are stored in row-scan order. The use of a non-default value for this tag requires setting the DNGBackwardVersion tag to at least 1.2.0.0.
