Constructors

this this(ushort x, ushort y, OutputScreen oW, size_t paletteLength, ubyte buffers): Creates a raster with the supplied parameters.

Destructor

~this ~this(): Undocumented in source.

Aliases

LayerMap alias LayerMap = TreeMap!(int, Layer): Undocumented in source.

Functions

addLayer void addLayer(Layer l, int i): Adds a layer at the given priority.
addPaletteChunk Color[] addPaletteChunk(Color[] paletteChunk): Adds a palette chunk to the end of the main palette.
addRefreshListener void addRefreshListener(RefreshListener r): Adds a RefreshListener to its list.
clearPaletteChunk Color[] clearPaletteChunk(ushort lenght, ushort offset): Clears an area of the palette with zeroes. Returns the original area.
getLayer Layer getLayer(int n): Undocumented in source. Be warned that the author may not have intended to support it.
getOutput SDL_Texture* getOutput(): Returns the workpad.
getPaletteIndex Color getPaletteIndex(ushort index): Undocumented in source. Be warned that the author may not have intended to support it.
isRefreshing bool isRefreshing(): Returns if the raster is refreshing.
loadLayers void loadLayers(R layerRange): Undocumented in source. Be warned that the author may not have intended to support it.
loadPalette Color[] loadPalette(Color[] palette): Loads a palette into the object. Returns the new palette of the object.
loadPaletteChunk Color[] loadPaletteChunk(Color[] paletteChunk, ushort offset): Loads a palette chunk into the object. The offset determines where the palette should be loaded. If it points to an existing place, the indices after that will be overwritten until the whole palette will be copied. If it points to the end or after it, then the palette will be made longer, and will pad with values 0x00_00_00_00 if needed. Returns the new palette of the object.
refresh void refresh(): Refreshes the whole framebuffer.
removeLayer void removeLayer(int n): Removes a layer at the given priority.
resetAvgfps void resetAvgfps(): Resets the avgFPS to zero.
setPaletteIndex Color setPaletteIndex(ushort index, Color val): Undocumented in source. Be warned that the author may not have intended to support it.
setupPalette void setupPalette(int i): Sets the number of colors.

Properties

avgfps real avgfps [@property getter]: Returns the current average FPS count.
fps real fps [@property getter]: Returns the current FPS count.
palette Color[] palette [@property getter]: Returns a copy of the palette of the object.

Variables

_palette Color[] _palette;: Color format is ARGB, with each index having their own transparency.
displayedBuffer ubyte displayedBuffer;: Framebuffer currently being displayed
fbData void* fbData;: Undocumented in source.
fbPitch int fbPitch;: Undocumented in source.
frameBuffer SDL_Texture*[] frameBuffer;: Undocumented in source.
layerMap LayerMap layerMap;: Stores the layers by their priorities.
nOfBuffers ubyte nOfBuffers;: Number of framebuffers, 2 for double buffering.
updatedBuffer ubyte updatedBuffer;: Framebuffer currently being updated

From IRaster

getOutput SDL_Texture* getOutput(): Undocumented in source.

From PaletteContainer

palette Color[] palette [@property getter]: Returns the palette of the object.
getPaletteIndex Color getPaletteIndex(ushort index): Returns the given palette index.
setPaletteIndex Color setPaletteIndex(ushort index, Color value): Sets the given palette index to the given value.
addPaletteChunk Color[] addPaletteChunk(Color[] paletteChunk): Adds a palette chunk to the end of the main palette.
loadPalette Color[] loadPalette(Color[] palette): Loads a palette into the object. Returns the new palette of the object.
loadPaletteChunk Color[] loadPaletteChunk(Color[] paletteChunk, ushort offset): Loads a palette chunk into the object. The offset determines where the palette should be loaded. If it points to an existing place, the indices after that will be overwritten until the whole palette will be copied. If it points to the end or after it, then the palette will be made longer, and will pad with values #00000000 if needed. Returns the new palette of the object.
clearPaletteChunk Color[] clearPaletteChunk(ushort lenght, ushort offset): Clears an area of the palette with zeroes. Returns the original area.
