找现成的字库，可以找 UCDOS 的，或者 Linux 的一些控制台下图形显示字库Top

我要提取多国语言的字库，不如日文，德文Top

请参考 GetGlyphOutlineW
不过我也不是很清楚的说

这是jishiping同志给我的帮助：
: ◆ 怎样提取汉字的点阵值 ◆ 一个32*32的汉字，怎样编程获取它点阵值？ 以0表示空白，1表示有点，以HEX形式存储。

A :
Graphics::TBitmap* Bmp;
Bmp = new Graphics::TBitmap;
Bmp->Monochrome = true; //黑白2色图形
Bmp->Width = 32; Bmp->Height = 32;
Bmp->Canvas->Font->Name = "宋体";
Bmp->Canvas->Font->Charset = GB2312_CHARSET;
Bmp->Canvas->Font->Height = -32;
Bmp->Canvas->Brush->Color = clBlack; //之前这儿前面少了Bmp->
Bmp->Canvas->Rectangle(0, 0, 32, 32); //用黑色填充图形
Bmp->Canvas->Font->Color = clWhite; //字的颜色为白色
Bmp->Canvas->TextOut(0, 0, "字"); //在图形上输出“字”，这样就
//得到了“字”的 32*32 的点阵
//下面的方法判断32×32点阵的每个点的颜色
for(int y=0; y<32; y++) {
BYTE bMask = 0x80; //之前这儿多了一个*
BYTE* pData = (BYTE*)Bmp->ScanLine[y];
for(int x=0; x<32; x++,bMask>>=1) {
if (bMask == 0) {
bMask = 0x80; pData++;
}
if (*pData & bMask)
; //点阵的 (x,y) 颜色为白色
else
; //点阵的 (x,y) 颜色为黑色
}
}
delete Bmp;Top

如果是ocr的话是否就是使用字体的点阵对照呢？
这样子速度是否很慢????Top

ocr用点阵对照? 不是吧.
手写体怎么对照呀.Top
