SpriteEncode (const SpriteLoader::SpriteCollection &sprite, SpriteAllocator &allocator) override
 Convert a sprite from the loader to our own format.
 
std::string_view GetName () override
 Get the name of the blitter, the same as the Factory-instance returns.
 
- Public Member Functions inherited from Blitter_8bppBase
uint8_t GetScreenDepth () override
 Get the screen depth this blitter works for. More...
 
void DrawColourMappingRect (void *dst, int width, int height, PaletteID pal) override
 Draw a colourtable to the screen. More...
 
void * MoveTo (void *video, int x, int y) override
 Move the destination pointer the requested amount x and y, keeping in mind any pitch and bpp of the renderer. More...
 
void SetPixel (void *video, int x, int y, uint8_t colour) override
 Draw a pixel with a given colour on the video-buffer. More...
 
void DrawLine (void *video, int x, int y, int x2, int y2, int screen_width, int screen_height, uint8_t colour, int width, int dash) override
 Draw a line with a given colour. More...
 
void DrawRect (void *video, int width, int height, uint8_t colour) override
 Make a single horizontal line in a single colour on the video-buffer. More...

void CopyToBuffer (const void *video, void *dst, int width, int height) override
 Copy from the screen to a buffer. More...
 
void CopyImageToBuffer (const void *video, void *dst, int width, int height, int dst_pitch) override

size_t BufferSize (uint width, uint height) override
 Calculate how much memory there is needed for an image of this size in the video-buffer. More...
 
void PaletteAnimate (const Palette &palette) override
 Called when the 8bpp palette is changed; you should redraw all pixels on the screen that are equal to the 8bpp palette indexes 'first_dirty' to 'first_dirty + count_dirty'. More...
 
Blitter::PaletteAnimation UsePaletteAnimation () override
 Check if the blitter uses palette animation at all. More...
 
- Public Member Functions inherited from Blitter
bool Is32BppSupported () override
