| //IMPORTANT: Call this function AFTER the call to 'SDL_SetVideoMode': |
| Draw_Init(); //Register the functions for current bpp |
| |
| |
| void Draw_Pixel(SDL_Surface *super, |
| Sint16 x, Sint16 y, Uint32 color); |
| |
| Draw a colored pixel on coordinates x,y. |
| |
| |
| void Draw_Line(SDL_Surface *super, |
| Sint16 x1, Sint16 y1, Sint16 x2, Sint16 y2, |
| Uint32 color); |
| |
| Draw a line from x1,y1 to x2,y2. |
| |
| |
| void Draw_Circle(SDL_Surface *super, |
| Sint16 x0, Sint16 y0, Uint16 r, |
| Uint32 color); |
| |
| Draw a circle with center x0,y0 and radius r. |
| |
| |
| void Draw_FillCircle(SDL_Surface *super, |
| Sint16 x0, Sint16 y0, Uint16 r, |
| Uint32 color); |
| |
| Draw a filled circle with center x0,y0 and radius r. |
| |
| |
| void Draw_HLine(SDL_Surface *super, |
| Sint16 x0,Sint16 y0, Sint16 x1, |
| Uint32 color); |
| |
| Draw a horizontal line from x0,y0 to x1,y0. |
| |
| |
| void Draw_VLine(SDL_Surface *super, |
| Sint16 x0,Sint16 y0, Sint16 y1, |
| Uint32 color); |
| |
| Draw a vertical line from x0,y0 to x0,y1. |
| |
| |
| void Draw_Rect(SDL_Surface *super, |
| Sint16 x,Sint16 y, Uint16 w,Uint16 h, |
| Uint32 color); |
| |
| Draw a rectangle with upper left corner in x,y being w the width and h the |
| height. |
| |
| |
| void Draw_FillRect(SDL_Surface *super, |
| Sint16 x,Sint16 y, Uint16 w,Uint16 h, |
| Uint32 color); |
| |
| The same as above but the rectangle is filled. This function is equivalent |
| to SDL_FillRect (is a MACRO). |
| |
| |
| void Draw_Ellipse(SDL_Surface *super, |
| Sint16 x0, Sint16 y0, |
| Uint16 Xradius, Uint16 Yradius, |
| Uint32 color); |
| |
| Draw a ellipse with center in x0,y0. Xradius is the major axis and Yradius is |
| the minor axis. |
| |
| |
| void Draw_FillEllipse(SDL_Surface *super, |
| Sint16 x0, Sint16 y0, |
| Uint16 Xradius, Uint16 Yradius, |
| Uint32 color); |
| |
| Draw a filled ellipse (same parameters as the above function). |
| |
| |
| void Draw_Round(SDL_Surface *super, |
| Sint16 x0,Sint16 y0, Uint16 w,Uint16 h, |
| Uint16 corner, Uint32 color); |
| |
| Draw a rectangle with rounded corners. x0,y0 is the upper left corner of the |
| rectangle, w is the width and h is the height. corner is the radius of the |
| corner. |
| |
| |
| void Draw_Round(SDL_Surface *super, |
| Sint16 x0,Sint16 y0, Uint16 w,Uint16 h, |
| Uint16 corner, Uint32 color); |
| |
| The same as above but the rounded rectangle is filled. |
