Code:
HDC hdc,bmp_hdc;
HBITMAP hPicture;
.....
hdc = BeginPaint(hwnd, &ps);
hBrush = CreateSolidBrush(RGB(230,230,230)); // Creating brush for background
SelectObject(hdc, hBrush);
Rectangle(hdc, 19, 49, 196, 194); // Drawing rectange that is 1 pixel larger than picture in every dimension
DeleteObject(hBrush);
/*The rectangle was created and filled with color,
secondly, created a BITMAPINFO structure;*/
BITMAPINFO bmp_info;
ZeroMemory( &bmp_info.bmiHeader, sizeof(BITMAPINFOHEADER) );
bmp_info.bmiHeader.biWidth = 16;//10;//4;//176; // width should be divided by 4
bmp_info.bmiHeader.biHeight = 16; // should be maybe minus mark to make it right
bmp_info.bmiHeader.biPlanes = 1;
bmp_info.bmiHeader.biBitCount = 8; // 24bit colors
bmp_info.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
bmp_info.bmiHeader.biSizeImage = 0;
bmp_info.bmiHeader.biCompression = BI_RGB; // No compression
bmp_info.bmiHeader.biClrUsed = 0; // When set to 0, colors used is counted on biBitCount
bmp_info.bmiHeader.biClrImportant= 0;
/*rest of the codes, I did like this:*/
bmp_hdc = CreateCompatibleDC(hdc);
hPicture = CreateDIBSection(hdc, &bmp_info, DIB_RGB_COLORS,NULL,NULL,0);
SelectObject(bmp_hdc,hPicture);
//now I copy size 16X16 from that rectangle to hPicture
BitBlt(bmp_hdc,0,0,16,16,hdc,19,49,SRCCOPY);
16, NULL, (BITMAPINFO*)&bmp_info, DIB_RGB_COLORS);
//again, show the hPicture in position (20,30) back in hdc
BitBlt(hdc,20,30,16,16,bmp_hdc,0,0,SRCCOPY);
