제가 전에 했던 작업중 샘플입니다.

Web상에서 Counter를 jpeg로 만들어서 뿌려주던 것입니다. 

#include "gd.h" 

#include "gdfontl.h"

    

void outCounter(long lTotal, long lToday)

{   

    gdImagePtr im;

    FILE *pngout, *jpegout;

    int black, white, back, blue;

    int nTextColor;

    int brect[8];

    int x, y, nXTop, nYLeft;

    int nSizeX, nSizeY;

    char s[40];

    char *f = "/usr/share/fonts/user/hatten.ttf";

    double sz = 12.;

    char *err; 

    sprintf(s, "Today:%08ld / Total:%08ld", lToday, lTotal);

    err = gdImageStringTTF(NULL,&brect[0],0,f,sz,0.,0,0,s);

    

    nSizeX = 180;

    nSizeY = brect[3]-brect[7] + 6;

    

    im = gdImageCreate(nSizeX, nSizeY);

    black = gdImageColorAllocate(im, 0, 0, 0);

    white = gdImageColorAllocate(im, 255, 255, 255);

    back = gdImageColorAllocate(im, 200, 200, 200);

    blue = gdImageColorAllocate(im, 211, 212, 223);

    nTextColor = gdImageColorAllocate(im, 12, 4, 89);

    gdImageFill(im, 1, 1, blue);

    nXTop = 5-brect[6];

    nYLeft = 13; 

    err = gdImageStringTTF(im,&brect[0],nTextColor,f,sz,0.0,nXTop,nYLeft,s);

    if (err) {fprintf(stderr,err); return;}

    

    printf("Content-type: image/jpeg\n\n");

    gdImageJpeg(im, stdout, -1);

    

    gdImageDestroy(im);

}
