Public Member Functions
void	Draw (Blitter::BlitterParams *bp, BlitterMode mode, ZoomLevel zoom) override
	Draw an image to the screen, given an amount of params defined above.

Sprite *	Encode (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.

void	DrawColourMappingRect (void *dst, int width, int height, PaletteID pal) override
	Draw a colourtable to the screen.

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.

void	SetPixel (void *video, int x, int y, uint8_t colour) override
	Draw a pixel with a given colour on the video-buffer.

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.

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.

void	CopyFromBuffer (void video, const void src, int width, int height) override
	Copy from a buffer to the screen.

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

void	CopyImageToBuffer (const void video, void dst, int width, int height, int dst_pitch) override
	Copy from the screen to a buffer in a palette format for 8bpp and RGBA format for 32bpp.

void	ScrollBuffer (void *video, int &left, int &top, int &width, int &height, int scroll_x, int scroll_y) override
	Scroll the videobuffer some 'x' and 'y' value.

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.

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'.

Blitter::PaletteAnimation	UsePaletteAnimation () override
	Check if the blitter uses palette animation at all.

Public Member Functions inherited from Blitter
