VC++ 截屏代码,并保存为想要的格式(BMP,JPG,PNG,GIF等格式)
void CCaptionScreenDlg::Screen(char* filename) { HDC hdcSrc = ::GetDC(NULL); int nBitPerPixel = GetDeviceCaps(hdcSrc, BITSPIXEL); int nWidth = GetDeviceCaps(hdcSrc, HORZRES); int nHeight = GetDeviceCaps(hdcSrc, VERTRES); CImage image; image.Create(nWidth, nHeight, nBitPerPixel); BitBlt(image.GetDC(), 0, 0, nWidth, nHeight, hdcSrc, 0, 0, SRCCOPY); ::ReleaseDC(NULL, hdcSrc); image.ReleaseDC(); image.Save((LPCTSTR)filename, Gdiplus::ImageFormatPNG);//ImageFormatJPEG }
