DIBDATA (Windows Embedded CE 6.0)

1/6/2010

This structure maintains information about each GDI DIB.

Syntax

typedef struct tagDIBDATA {
  LONG PaletteVersion;
  DIBSECTION DibSection; 
  HBITMAP hBitmap; 
  HANDLE hMapping;
  BYTE* pBase;
} DIBDATA;

Members

  • PaletteVersion
    Current palette version in use.
  • DibSection
    Details of DIB section allocated.
  • hBitmap
    Handle to bitmap for drawing.
  • hMapping
    Handle to shared memory block.
  • pBase
    Pointer to base memory address.

Remarks

When the allocator creates a sample, it allocates a DIBSECTION to the sample.

When a window receives a sample, it can call the Microsoft Win32® BitBlt function to pass the sample from one device context to another device context.

This is a mechanism for the image allocator, an image sample, and the draw class to pass bitmap information to each other.

Requirements

Windows Embedded CE Windows CE 2.12 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
