我正在尝试使用此代码:
bool SaveBMPFile(char *filename, HBITMAP bitmap, HDC bitmapDC, int width, int height);
bool ScreenCapture(int x, int y, int width, int height, char *filename){
// get a DC compat. w/ the screen
HDC hDc = CreateCompatibleDC(0);
// make a bmp in memory to store the capture in
HBITMAP hBmp = CreateCompatibleBitmap(GetDC(0), width, height);
// join em up
SelectObject(hDc, hBmp);
// copy from the screen to my bitmap
BitBlt(hDc, 0, 0, width, height, GetDC(0), x, y, SRCCOPY);
// save my bitmap
bool ret = SaveBMPFile(filename, hBmp, hDc, width, height);
// free the bitmap memory
DeleteObject(hBmp);
return ret;
}
它抛出这些错误:
bot.c|185|error: expected '=', ',', ';', 'asm' or '__attribute__' before 'SaveBMPFile'|
bot.c|187|error: expected '=', ',', ';', 'asm' or '__attribute__' before 'ScreenCapture'|
我能做些什么?尝试不同的代码不起作用,并尝试使用 Gdi+- 也错误。
