Hi,<br />
I have a graphic application the draw images into off-screen buffer. 1000 times in a second the buffer pixels should be captured to memory. ( I need to pass the off-screen pixels to another application that compress the frame.) I have a code sample that uses CreateDIBSection and pass pBits. This way pBits provides me direct access to the pixels.<br />
<br />
What is the most efficient way to do it?<br />
<br />
hDesktopCompatibleDC=Creat<wbr />eCompatibl<wbr />eDC(hDeskt<wbr />opDC);<br />
hDesktopCompatibleBitmap=C<wbr />reateDIBSe<wbr />ction(hDes<wbr />ktopDC,&amp;bm<wbr />pInfo,DIB_<wbr />RGB_COLORS<wbr />,&amp;pBits,NU<wbr />LL,0);<br />
if(hDesktopCompatibleDC==N<wbr />ULL || hDesktopCompatibleBitmap == NULL)

Efficient way to access off-screen buffer memory

Game programming is the software development of video games. Game programming requires substantial skill in software engineering as well as specialization in simulation, computer graphics, artificial intelligence, physics, audio programming, and input. Like other software, game development programs are generated from source code to the actual program by a compiler. Source code can be developed with almost any text editor, but most professional game programmers use a full integrated development environment (IDE).

Multimedia programming is the process of developing multimedia products, programs or services that combine text with sounds, pictures, graphics, video-clips, virtual reality, digital animation and other forms of media, and generally requires skill sets that include programming languages such as Java and C++, graphics, animation and video production.

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
