SDL_Draw (http://sdl-draw.sourceforge.net/) is a simple library to draw basic elements, like points, lines and circles, on SDL surfaces.

Library API:

#include "SDL_draw.h"

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_FillRound(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.
