| 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 | |

| 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... | |

| Copy from a buffer to the screen. 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 |
| Copy from the screen to a buffer in a palette format for 8bpp and RGBA format for 32bpp. More... | |
| 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. More... | |
| 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 |
| Can the sprite encoder make use of RGBA sprites? | |
| virtual bool | NeedsAnimationBuffer () |
| Does this blitter require a separate animation buffer from the video backend? | |
| virtual void | PostResize () |
| Post resize event. | |
| template<typename SetPixelT > | |
