Parameters

row

Number of requested row.

Return Value

In ImageGear, all rasters are kept and indexed in the normal form: the first raster is the top raster, the last raster is the bottom raster. This differs from BMP and older ImageGear versions, where rasters are stored in reverse mode: from bottom to top.

Rasters in ImageGear pixel storage are DWORD-aligned.

Raster size for standard DIBs (not run-ends) in ImageGear can be calculated using the following formula:

The +31 and & ~31 indicate DWORD alignment. The raster size is in terms of channel values. To calculate the raster size in terms of bytes, divide by 8 instead of BitsPerChannel.
