Hello Guys,
i need help with some code of mine. I am using GDIPlus and am trying to create a Get Pixel Function. My Function works fine, but unfortunately i get some weird memory issues. My GDI-Object counter in task manager increases, but I dont know why. Especially since it is not a big increase, but a small one, like 2 GDI Objects in 5 minutes eventhough i call the function multiple times per second. I added the function down here.
Best regards, thanks for the help!
INT GetColor(INT iX, INT iY, HWND WinHandle) {
int value = 0;
Gdiplus::GdiplusStartupInput gdiplusStartupInput;
ULONG_PTR gdiplusToken;
Gdiplus::GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);
RECT rect;
int WindowWidth;
int WindowHeight;
if (GetWindowRect(WinHandle, &rect))
{
WindowWidth = rect.right - rect.left;
WindowHeight = rect.bottom - rect.top;
}
HDC hDDC = GetDC(WinHandle);
HDC hCDC = CreateCompatibleDC(hDDC);
HBITMAP hBMP = CreateCompatibleBitmap(hDDC, WindowWidth, WindowHeight);
SelectObject(hCDC, hBMP);
BitBlt(hCDC, 0, 0, WindowWidth, WindowHeight, hDDC, 0, 0, SRCCOPY);
Gdiplus::Bitmap *BMP = new Gdiplus::Bitmap(hBMP, NULL);
Gdiplus::Color PixelColor;
BMP->GetPixel(iX, iY, &PixelColor);
Value = PixelColor.GetValue();
ReleaseDC(WinHandle, hDDC);
DeleteDC(hDDC);
DeleteDC(hCDC);
DeleteObject(hBMP);
delete BMP;
DeleteObject(BMP);
Gdiplus::GdiplusShutdown(gdiplusToken);
return Value;
}
