TileLayer.DisplayListItem

Implements a single tile to be displayed. Is ordered in a BinarySearchTree for fast lookup.

struct DisplayListItem {

ABitmap tile;

void* pixelDataPtr;

ubyte wordLength;

ubyte paletteSh;

this(wchar ID, ABitmap tile, ubyte paletteSh);

toString string toString(): Undocumented in source. Be warned that the author may not have intended to support it.

Variables

ID wchar ID;: ID, mainly as a padding to 32 bit alignment
paletteSh ubyte paletteSh;: Sets the maximum accessable color amount by the bitmap. By default, for 4 bit bitmaps, it's 4, and it enables 256 * 16 color palettes. This limitation is due to the way how the MappingElement struct works. 8 bit bitmaps can assess the full 256 * 256 palette space. Lower values can be described to avoid wasting palettes space in cases when the bitmaps wouldn't use their full capability.
pixelDataPtr void* pixelDataPtr;: points to the pixeldata
tile ABitmap tile;: reference counting only
wordLength ubyte wordLength;: to avoid calling the more costly classinfo
