主要的代码如下：
void CICETIMDlg::OnBtnSavepixel()
{
// TODO: Add your control notification handler code here
if(m_dib.GetHeight()==0)
{
AfxMessageBox("对不起，请先打开位图文件");
return;
}
CString fileName;
char szFilter[]="文本文件(*.txt)|*.txt|All Files(*.*)|*.*||";
CFileDialog dlg(false,"*.txt",NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,szFilter);
if(dlg.DoModal()==IDOK)
{
UpdateData(true);
fileName=dlg.GetPathName();
}
else
{
return;
}
//从CString转换到char*
fileName.Replace(_T("
//"),_T(""));
char* filename=(char*)fileName.GetBuffer(fileName.GetLength());
fileName.ReleaseBuffer();
ofstream outfile;
outfile.open(filename);
int nHeight=m_dib.GetHeight();
int nWidth=m_dib.GetWidth();
int nBitCount=m_dib.GetBitCount();
long lLineBytes=m_dib.GetLineBytes();
outfile<<"*****图片信息*****/r/n";
outfile<<"图像高度:"<<nHeight<<"/r/n";
outfile<<"图像宽度:"<<nWidth<<"/r/n";
outfile<<"图像位数:"<<nBitCount<<"/r/n";
outfile<<"图像每行所占的字节数:"<<lLineBytes<<"/r/n";
outfile<<"****************"<<"/r/n";
BYTE* pdib=m_dib.GetDibData();
for(int i=0;i<nHeight;i++)
{
for(int j=0;j<lLineBytes;j++)
{
BYTE B,G,R;
B=*(pdib+lLineBytes*(nHeight-1-i)+j);
if(nBitCount==8)
{
outfile<<"("<<(nHeight-1-i)<<","<<j<<")="<<(int)B<<"/r/n";
}
else
{
outfile<<"("<<(nHeight-1-i)<<","<<j<<")=B"
<<(int)B<<"/r/n";
j++;
G=*(pdib+lLineBytes*(nHeight-1-i)+j);
outfile<<"("<<(nHeight-1-i)<<","<<j<<")=G"
<<(int)G<<"/r/n";
j++;
R=*(pdib+lLineBytes*(nHeight-1-i)+j);

<<(int)R<<"/r/n";
}
}
outfile<<"/r/n";
}
outfile.close();
}
