moveto moves the current position (CP) to viewport position (x,y).
/* moveto example */ #include <graphics.h> #include <stdlib.h> #include <stdio.h> #include <conio.h> int main(void) { /* request autodetection */ int gdriver = DETECT, gmode, errorcode; char msg[80]; /* initialize graphics and local variables */ initgraph(&gdriver, &gmode, ""); /* read result of initialization */ errorcode = graphresult(); if (errorcode != grOk) { /* an error occurred */ printf("Graphics error: %s\n", grapherrormsg(errorcode)); printf("Press any key to halt:"); getch(); exit(1); /* terminate with an error code */ } /* move the CP to location (20,30) */ moveto(20,30); /* plot a pixel at the CP */ putpixel(getx(), gety(), getmaxcolor()); /* create and output a message at (20,30) */ sprintf(msg, " (%d, %d)", getx(), gety()); outtextxy(20,30, msg); /* move to (100,100) */ moveto(100,100); /* plot a pixel at the CP */ putpixel(getx(), gety(), getmaxcolor()); /* create and output a message at CP */ sprintf(msg, " (%d, %d)", getx(), gety()); outtext(msg); /* clean up */ getch(); closegraph(); return 0; }
no output of example at the moment
do not hesitate and add it...
