Public Member Functions | |
void | Draw (Blitter::BlitterParams *bp, BlitterMode mode, ZoomLevel zoom) |
Draws a sprite to a (screen) buffer. | |
void | DrawColourMappingRect (void *dst, int width, int height, PaletteID pal) |
Draw a colourtable to the screen. | |
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 | 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. | |
const char * | GetName () |
Get the name of the blitter, the same as the Factory-instance returns. | |
int | GetBytesPerPixel () |
Get how many bytes are needed to store a pixel. | |
void | PostResize () |
Post resize event. | |
Colour | LookupColourInPalette (uint index) |
Look up the colour in the current palette. | |
template<BlitterMode mode> | |
void | Draw (const Blitter::BlitterParams *bp, ZoomLevel zoom) |
Draws a sprite to a (screen) buffer. | |
Private Attributes | |
uint16 * | anim_buf |
In this buffer we keep track of the 8bpp indexes so we can do palette animation. | |
int | anim_buf_width |
The width of the animation buffer. | |
int | anim_buf_height |
The height of the animation buffer. | |
Palette | palette |
The current palette. |

width | the width of the buffer. | |
height | the height of the buffer. | |
pal | the palette to use. |
