Public Member Functions inherited from Blitter_8bppBase | |
| uint8 | GetScreenDepth () |
| Get the screen depth this blitter works for. | |
| void | DrawColourMappingRect (void *dst, int width, int height, PaletteID pal) |
| Draw a colourtable to the screen. | |
| void * | MoveTo (void *video, int x, int y) |
| 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 colour) |
| Draw a pixel with a given colour on the video-buffer. | |
| void | DrawRect (void *video, int width, int height, uint8 colour) |
| Make a single horizontal line in a single colour on the video-buffer. | |
| void | CopyFromBuffer (void *video, const void *src, int width, int height) |
| Copy from a buffer to the screen. | |
| void | CopyToBuffer (const void *video, void *dst, int width, int height) |
| Copy from the screen to a buffer. | |
| void | CopyImageToBuffer (const void *video, void *dst, int width, int height, int dst_pitch) |
| 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) |
| Scroll the videobuffer some 'x' and 'y' value. | |
| int | BufferSize (int width, int height) |
| Calculate how much memory there is needed for an image of this size in the video-buffer. | |
| void | PaletteAnimate (const Palette &palette) |
| 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 () |
| Check if the blitter uses palette animation at all. | |
| int | GetBytesPerPixel () |
| Get how many bytes are needed to store a pixel. | |
