哪里有能够将字体转换为图片的工具？

[天拉噜]

就像在 xp 的画图中输入一个汉字，然后保存成一定大小的图片，不过要求能将输入的字做一下点阵化处理，看起来这个字是由肉眼能够分辨的点阵构成的，请问哪里有这样的软件?

没人回答吗？散分了

不复杂，得到窗口的DC，保存为.bmp，参考下面的代码（创建的为屏幕大小的DC）：
void CaptureScreen(char* bmpname)
{

HDC hScrDC, hMemDC;

int nX, nY, nX2, nY2;

int xScrn, yScrn;

HBITMAP hBitmap, hOldBitmap;


hScrDC = CreateDC("DISPLAY", NULL, NULL, NULL);

hMemDC = CreateCompatibleDC(hScrDC);

xScrn = GetDeviceCaps(hScrDC, HORZRES);
yScrn = GetDeviceCaps(hScrDC, VERTRES);

nX = 0;
nY = 0;
nX2 = xScrn;
nY2 = yScrn;

// 创建一个与屏幕设备描述表兼容的位图
hBitmap = CreateCompatibleBitmap(hScrDC, nX2, nY2);

hOldBitmap = (HBITMAP)SelectObject(hMemDC, hBitmap);

BitBlt(hMemDC, 0, 0, nX2, nY2, hScrDC, nX, nY, SRCCOPY);

hBitmap = (HBITMAP)SelectObject(hMemDC, hOldBitmap);

DeleteDC(hScrDC);
DeleteDC(hMemDC);

HDC hDC;
int iBits;

WORD wBitCount;

DWORD dwPaletteSize=0,
dwBmBitsSize,
dwDIBSize, dwWritten;
BITMAP Bitmap;

BITMAPFILEHEADER bmfHdr;

BITMAPINFOHEADER bi;

LPBITMAPINFOHEADER lpbi;

HANDLE fh, hDib, hPal,hOldPal=NULL;



hDC = CreateDC("DISPLAY",NULL,NULL,NULL);
iBits = GetDeviceCaps(hDC, BITSPIXEL) *
GetDeviceCaps(hDC, PLANES);
DeleteDC(hDC);
if (iBits <= 1)
wBitCount = 1;
else if (iBits <= 4)
wBitCount = 4;
else if (iBits <= 8)
wBitCount = 8;
else if (iBits <= 24)
wBitCount = 24;
else
wBitCount = iBits;

if (wBitCount <= 8)
dwPaletteSize = (1 << wBitCount) *
sizeof(RGBQUAD);


GetObject(hBitmap, sizeof(BITMAP), (LPSTR)&Bitmap);
bi.biSize = sizeof(BITMAPINFOHEADER);
bi.biWidth = Bitmap.bmWidth;
bi.biHeight = Bitmap.bmHeight;
bi.biPlanes = 1;
bi.biBitCount = wBitCount;
bi.biCompression = BI_RGB;
bi.biSizeImage = 0;
bi.biXPelsPerMeter = 0;
bi.biYPelsPerMeter = 0;
bi.biClrUsed = 0;
bi.biClrImportant = 0;

dwBmBitsSize = ((Bitmap.bmWidth * wBitCount+31)/32) * 4 * Bitmap.bmHeight;

hDib = GlobalAlloc(GHND,dwBmBitsSize+dwPaletteSize+sizeof(BITMAPINFOHEADER));
lpbi = (LPBITMAPINFOHEADER)GlobalLock(hDib);
*lpbi = bi;


hPal = GetStockObject(DEFAULT_PALETTE);
if (hPal)
{
hDC = ::GetDC(NULL);
hOldPal = SelectPalette(hDC,(HPALETTE)hPal, FALSE);
RealizePalette(hDC);
}

GetDIBits(hDC, hBitmap, 0, (UINT) Bitmap.bmHeight,(LPSTR)lpbi + sizeof(BITMAPINFOHEADER)+dwPaletteSize,(BITMAPINFO*)lpbi,DIB_RGB_COLORS);

if (hOldPal)
{
SelectPalette(hDC, (HPALETTE)hOldPal, TRUE);
RealizePalette(hDC);
::ReleaseDC(NULL, hDC);
}


fh = CreateFile(bmpname, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL | FILE_FLAG_SEQUENTIAL_SCAN, NULL);

bmfHdr.bfType = 0x4D42;
dwDIBSize = sizeof(BITMAPFILEHEADER) + sizeof(BITMAPINFOHEADER) + dwPaletteSize + dwBmBitsSize;
bmfHdr.bfSize = dwDIBSize;
bmfHdr.bfReserved1 = 0;
bmfHdr.bfReserved2 = 0;
bmfHdr.bfOffBits = (DWORD)sizeof
(BITMAPFILEHEADER) + (DWORD)sizeof(BITMAPINFOHEADER) + dwPaletteSize;

WriteFile(fh, (LPSTR)&bmfHdr, sizeof(BITMAPFILEHEADER), &dwWritten, NULL);

WriteFile(fh, (LPSTR)lpbi, dwDIBSize,
&dwWritten, NULL);

GlobalUnlock(hDib);
GlobalFree(hDib);
CloseHandle(fh);
}

上面的传递的参数为一个bmp文件名，执行该函数直接得到图形文件

多谢，我试试先
