Hi

What is the relationship between a BITMAPINFOHEADER and a HBITBMAP?

I have a LPBITMAPINFOHEADER but i want a HBITMAP so i can display it in a CStatic.


Cheers

Richard

Don't think that you can do it in some easy way. Why you have only LPB...ER?

I am using AVI api, to return a single frame. The frame data is returned as a packed DIB.

All i want to do is display it!

Thanks Again

than display dib directly, can you show your code or tell which function do you using?

CreateDIBitmap() is your function:

HBITMAP CreateDIBitmap(
  HDC hdc,     // handle to device context
  CONST BITMAPINFOHEADER *lpbmih,  // ptr to bmp size and
                                   // format data
  DWORD fdwInit,            // initialization flag
  CONST VOID *lpbInit,      // ptr to initialization data
  CONST BITMAPINFO *lpbmi,  // ptr to bmp color-format data
  UINT fuUsage              // color-data usage
);

lpbInit points to your packed DIB-data.
You must create a BITMAPINFO structure which describes the bitmap.

I'm not sure if this works with packed DIBs ...
But it's worth a try.

CreateDIBitmap() is definetely my function! Cheers

The only thing is i am struggling with the fourth paramter ptr to initialisation data, i guess i need to manipulate my LPBitmapInfoheader.  But i dunno how!

Thanks Again Richard

lpbInit is the bitmap data itself.
