The system closes the handle to that memory when you later delete the DIB by calling the DeleteObject function. DIB_RGB_COLORS : DIB_PAL_COLORS; // *** bi.bmiHeader.biSize = sizeof(BITMAPINFOHEADER); bi.bmiHeader.biBitCount = format.bpp; bi.bmiHeader.biSizeImage = (format.bpp / 8) * width_ * height_; bi.bmiHeader.biPlanes = 1; bi.bmiHeader.biWidth = width_; bi.bmiHeader.biHeight = -height_; bi.bmiHeader.biCompression = TRANSLATORS: "pixmap" is an X11 concept and may not be suitable #. to translate. #: vncviewer/X11PixelBuffer.cxx:72 msgid "Couldn't find suitable pixmap format" msgstr "Kunde inte hitta lämpligt pixmap-format" #: vncviewer/X11PixelBuffer.cxx:81 msgid "Only true colour displays supported" msgstr "Endast skärmar med true colour stöds" https://msdn.microsoft.com/en-us/library/windows/desktop/dd183494(v=vs.85).aspx

You need to guarantee that the GDI subsystem has completed any drawing to a bitmap created by CreateDIBSection before you draw to the bitmap yourself. TRANSLATORS: "pixmap" is an X11 concept and may not be suitable #. If hSection is not NULL, the CreateDIBSection function locates the bitmap bit values at offset dwOffset in the file-mapping object referred to by hSection. share|improve this answer answered Sep 18 '09 at 1:47 MusiGenesis 56.7k30142281 Thanks!

An application can later retrieve the hSection handle by calling the GetObject function with the HBITMAP returned by CreateDIBSection. If the value of iUsage is DIB_PAL_COLORS, the function uses this device context's logical palette to initialize the DIB colors.

Access to the bitmap must be synchronized. You signed in with another tab or window.

If hSection is not NULL, it must be a handle to a file-mapping object created by calling the CreateFileMapping function with the PAGE_READWRITE or PAGE_WRITECOPY flag.

I do not think there are simple mapping of win32 api to Qt5 api, this may consume you lot of times if your project are big.
