textprintf_justify_ex(3) Formatted justified output of a string. Allegro game programming library.


#include <allegro.h>

void textprintf_justify_ex(BITMAP *bmp, const FONT *f, int x1, x2, y, diff, color, bg, const char *fmt, ...);


Like textout_justify_ex(), but using a printf() style format string. This function shares the text length limitation of textprintf_ex(). Example:

   char *lines[] = {"Line %02d: Draws justified text",
                    "Line %02d: within the specified",
                    "Line %02d: x2-x1 area. But not",
                    "Line %02d: T H I S !", NULL};
   /* Show the justification marker. */
   vline(screen, 300, 0, SCREEN_H-1, makecol(0, 0, 0));
   /* Draw all the lines until we reach a NULL entry. */
   for (num = 0, y = 0; lines[num]; num++, y += text_height(font))
      textprintf_justify_ex(screen, font, 0, 300, y, 180,
                            makecol(0, 0, 0), makecol(255, 255, 255),
                            lines[num], num);
