done()

void Source4Bpp::done ( )

inlineoverridevirtual

Done reading bitmap data

Any open files can be closed now

Implements SourcePresentation.

{};

fillTiles()

void Source4Bpp::fillTiles ( int  startLine, int  lineCount, int  tileWidth, int  firstTile, std::vector< Tile::Ptr > &  tiles  )

overridevirtual

Provide bitmap data

While the TiledBitmap is loaded, this function will be called several times. Each time, this function has to fill the provided tiles with bitmap data.

The given tiles are horizontally adjacent.

Parameters

startLine	y coordinate of the first line in the set of tiles
lineCount	The number of lines that are to be filled. This equals the height of the tiles
tileWidth	The width of one tile
firstTile	Index of the first tile provided. This means that the first x coordinate is firsttile * tileWidth
tiles	The tiles that are to be filled.

Implements SourcePresentation.

{
  for(const Tile::Ptr& tile: tiles)
  {
    byte* data = tile->data.get();
    for(int y = 0; y < lineCount; y++)
    {
      for(int x = 0; x < tileWidth / 2; x++)
      {
        byte const v = 2 * x + y;
 
        *data = ((v & 0xF) << 4) | ((v + 1) & 0xF);
        data++;
      }
    }
  }
}

getName()

std::string Source4Bpp::getName ( )
