Detailed Description

Interface to Convert Bitmap Image into Tilemap.

Note: Maximum Size of bitmap to convert is 0x20000 bytes (512x512 @ 4bpp, 512x256 @ 8bpp, or 256x256 @ 16bpp).; Empty tiles in the source image are detected and removed from the tileset, but duplicate and mirrored tiles are not.; In cases where bitmap is below maximum size or contains empty tiles, a default empty tile is written at start of tileset.

Public Member Functions
	Bmp2Tile (SRL::Bitmap::IBitmap &bmp, uint8_t pages=1)
	Create a Tilemap out of an existing Bitmap.

	~Bmp2Tile ()
	Free allocated resources and destroy Bmp2Tile object.

void	ApplyVdp2Offsets (uint32_t celOffset, uint32_t palOffset=0)
	manually apply a cel offset and Palette offset to all map data for cases when bypassing built in VDP2 tilemap loading functions (such as when performing DMA transfers to VDP2 VRAM)

void	ClearPage (int pageIndex)
	clears all data of a page in the tilemap to zero

void	CopyMap (uint8_t sourcePage, Tilemap::Coord topLeft, Tilemap::Coord botRight, uint8_t destPage, Tilemap::Coord destTile)
	Copies a rectangular selection of Tilemap data between 2 pages in the tilemap.

void	FreeCellData ()
	Frees The Work Ram associated with Cell Data in cases where it is no longer required.

void	FreeMapData ()
	Frees The Work Ram associated with Map Data in cases where it is no longer required.

void	FreePalData ()
	Frees The Work Ram associated with Pal Data in cases where it is no longer required.

void *	GetCellData () override
	Get Cell data(Tileset)
