+ | ====Syntax of outtextxy ==== | ||
+ | <code c> | ||
+ | #include <graphics.h> | ||
+ | void outtextxy(int x, int y, char *textstring); | ||
+ | </code> | ||
+ | |||
+ | |||
+ | ==== Description of outtextxy ==== | ||
+ | <code c> | ||
+ | outtextxy displays a text string in the viewport at the given position | ||
+ | (x, y), using the current justification settings and the current font, | ||
+ | direction, and size. | ||
+ | To maintain code compatibility when using several fonts, use textwidth | ||
+ | and textheight to determine the dimensions of the string. | ||
+ | If a string is printed with the default font using outtext or outtextxy, | ||
+ | any part of the string that extends outside the current viewport is | ||
+ | truncated. | ||
+ | outtextxy is for use in graphics mode; it will not work in text mode. | ||
+ | </code> | ||
