DIBDATA Structure

The DIBDATA structure caintains 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.
