Functions

void caca_draw_line (int, int, int, int, char)
 Draw a line on the screen using the given character. More...

void caca_draw_polyline (int const x[], int const y[], int, char)
 Draw a polyline on the screen using the given character and coordinate arrays. The first and last points are not connected, so in order to draw a polygon you need to specify the starting point at the end of the list as well. More...

void caca_draw_thin_line (int, int, int, int)
 Draw a thin line on the screen, using ASCII art. More...

void caca_draw_thin_polyline (int const x[], int const y[], int)
 Draw a thin polyline on the screen using the given coordinate arrays and with ASCII art. The first and last points are not connected, so in order to draw a polygon you need to specify the starting point at the end of the list as well. More...

void caca_draw_circle (int, int, int, char)
 Draw a circle on the screen using the given character. More...

void caca_draw_ellipse (int, int, int, int, char)
 Draw an ellipse on the screen using the given character. More...

void caca_draw_thin_ellipse (int, int, int, int)
 Draw a thin ellipse on the screen. More...
