Im trying to create a pixel search function, but i keep getting memory leaks and i cant figure out why. I fixed 1 put another popped up. Was wondering what im doing wrong.
}
public Bitmap capturescreen(Rectangle rect)
{
Size sz = Screen.PrimaryScreen.Bounds.Size;
IntPtr hDesk = GetDesktopWindow();
IntPtr hSrce = GetWindowDC(hDesk);
IntPtr hDest = CreateCompatibleDC(hSrce);
IntPtr hBmp = CreateCompatibleBitmap(hSrce, sz.Width, sz.Height);
IntPtr hOldBmp = SelectObject(hDest, hBmp);
bool b = BitBlt(hDest, 0, 0, rect.Width, rect.Height, hSrce, 0, 0, CopyPixelOperation.SourceCopy | CopyPixelOperation.CaptureBlt);
Bitmap bmp = Bitmap.FromHbitmap(hBmp); // <-------- Says out of memory on this line.
SelectObject(hDest, hOldBmp);
DeleteObject(hBmp);
DeleteDC(hDest);
ReleaseDC(hDesk, hSrce);
return bmp;
}
}
}
Here is the pixel search function which uses the function above
public Point PixelSearch(Rectangle rect, int PixelColor, int Shade_Variation)
{
Color Pixel_Color = Color.FromArgb(PixelColor);
Point Pixel_Coords = new Point(-1, -1);
Bitmap RegionIn_Bitmap = capturescreen(rect);
BitmapData RegionIn_BitmapData = RegionIn_Bitmap.LockBits(new Rectangle(0, 0, RegionIn_Bitmap.Width, RegionIn_Bitmap.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb);
int[] Formatted_Color = new int[3] { Pixel_Color.B, Pixel_Color.G, Pixel_Color.R }; //bgr
unsafe
{
for (int y = 0; y < RegionIn_BitmapData.Height; y++)
{
byte* row = (byte*)RegionIn_BitmapData.Scan0 + (y * RegionIn_BitmapData.Stride);
for (int x = 0; x < RegionIn_BitmapData.Width; x++)
{
if (row[x * 3] >= (Formatted_Color[0] - Shade_Variation) & row[x * 3] <= (Formatted_Color[0] + Shade_Variation)) //blue
{
if (row[(x * 3) + 1] >= (Formatted_Color[1] - Shade_Variation) & row[(x * 3) + 1] <= (Formatted_Color[1] + Shade_Variation)) //green
{
if (row[(x * 3) + 2] >= (Formatted_Color[2] - Shade_Variation) & row[(x * 3) + 2] <= (Formatted_Color[2] + Shade_Variation)) //red
{
Pixel_Coords = new Point(x + rect.X, y + rect.Y);
goto end;
}
}
}
}
}
}
end:
RegionIn_Bitmap.UnlockBits(RegionIn_BitmapData);
return Pixel_Coords;
}
