标题: 求助:能帮我写段代码吗?
webalizer 中graphs.c因该是用C编的吧,我对C一窍不通...
  1. void init_graph(char *title, int xsize, int ysize)
  2. {
  3.    int i;

  5.    im = gdImageCreate(xsize,ysize);

  7.    /* allocate color maps, background color first (grey) */
  8.    grey    = gdImageColorAllocate(im, 192, 192, 192);
  9.    dkgrey  = gdImageColorAllocate(im, 128, 128, 128);
  10.    black   = gdImageColorAllocate(im, 0, 0, 0);
  11.    white   = gdImageColorAllocate(im, 255, 255, 255);
  12.    green   = gdImageColorAllocate(im, 0, 128, 92);
  13.    orange  = gdImageColorAllocate(im, 255, 128, 0);
  14.    blue    = gdImageColorAllocate(im, 0, 0, 255);
  15.    red     = gdImageColorAllocate(im, 255, 0, 0);
  16.    cyan    = gdImageColorAllocate(im, 0, 192, 255);
  17.    yellow  = gdImageColorAllocate(im, 255, 255, 0);

  19.    /* make borders */

  21.    for (i=0; i<5 ;i++)          /* do shadow effect */
  22.    {
  23.       gdImageLine(im, i, i, xsize-i, i, white);
  24.       gdImageLine(im, i, i, i, ysize-i, white);
  25.       gdImageLine(im, i, ysize-i-1, xsize-i-1, ysize-i-1, dkgrey);
  26.       gdImageLine(im, xsize-i-1, i, xsize-i-1, ysize-i-1, dkgrey);
  27.    }

  29.    gdImageRectangle(im, 20, 25, xsize-21, ysize-21, black);
  30.    gdImageRectangle(im, 19, 24, xsize-22, ysize-22, white);
  31.    gdImageRectangle(im, 0, 0, xsize-1, ysize-1, black);
  32.    gdImageStringFT(im,0,blue,myfont,10,0.0,20,8,title);    /*
  33.    return;
  34. }
复制代码

想把char *title由GB2312编码变成UTF-8编码怎么做?
gdImageStringFT(im,0,blue,myfont,10,0.0,20,8,"汉字";生成的图片中汉字是乱码 ,
gdImageStringFT(im,0,blue,myfont,10,0.0,20,8,"锘挎眽瀛";生成的图片汉字正常了.......

我觉得
#include <iconv.h>;
...
fd = iconv_open("UTF-8", "936";
trans_size = iconv(fd, &fromstr_p, &fromsize, &tostr_p, &tosize);
iconv_close(fd);
.....
就是我要用的......
gdImageStringFT字符肯定要UTF-8才能正确显示汉字.
谢谢!
