Question

I want to draw image(bmp) using an image pointer by VS2005(MFC).

But I don’t know how to draw an image using image pointer.

Below is my code:

PVOID m_pBuffer;
m_pBuffer = lBuffer->GetDataPointer(); //lBuffer is offered parameter by Camera Company.
                                       //and GetDataPointer() funcion is 'A pointer to the memory pointer'

How do I draw an image using image pointer?
(ex. use GDI, GDI+, CImage..)

Depending what you want to do with it have a look at both CreateBitmap and CreateDIBSection.

To use CreateBitmap lpBits is where you pass in your m_pBuffer. Make sure the bitmap is the same format as your data!

For a 24bit BMP at 800×600:

HBITMAP MyBmp = CreateBitmap(800, 600, 1, 24, m_pBuffer);
