The latest version of this library is available from: http://sourceforge.net/projects/sdl-draw/

This library is under the GNU Library General Public License, see the file "COPYING" for details in the source code distribution.

SDL_draw is a simple library to draw basic elements, like points, lines and circles, on SDL surfaces. It's the primitive drawing library that SDL (Simple DirectMedia Layer) needed!! :-)

Our native language is spanish. If you read something bad or misunderstanding, please send a message to some forum in the SourceForge library page.

If you use the library, we'd like to know it. Please, send us a message to some forum in the SourceForge library page and we'll put a link in this web page.

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.

The file sdldrawtest.c is a example application for the library. You can compile it using (for the GNU Compiler):

  

  $ export CFLAGS="`sdl-config --cflags` -I./include"

  $ export LIBS="`sdl-config --libs` ./src/.libs/libSDL_draw.a"

  $ gcc -o sdldrawtest sdldrawtest.c -Wall $CFLAGS $LIBS
