DIBSECTION

This structure contains information about a device-independent bitmap (DIB).

At a Glance

Syntax

typedef struct tagDIBSECTION {
BITMAP dsBm;
BITMAPINFOHEADER dsBmih;
DWORD dsBitfields[3];
HANDLE dshSection;
DWORD dsOffset;
} DIBSECTION;

Members

dsBm

Specifies a BITMAP data structure that contains information about the device-independent bitmap: its type, dimensions, color capacities, and a pointer to its bit values.

dsBmih

Specifies a bitmap information header structure that contains information about the color format of the DIB. Use the BITMAPINFOHEADER structure.

dsBitfields

Specifies three DWORD color masks for the device-independent bitmap. This member is only valid when the BitCount member of the BITMAP INFORMATION HEADER structure has a value greater than 8. Each color mask indicates the bits within a DWORD used to encode one of the three color channels (red, green, and blue).

dshSection

Contains a handle to the file mapping object that the CreateDIBSection function used to create the device-independent bitmap. If CreateDIBSection was called with a NULL value for its hSection parameter, causing the system to allocate memory for the bitmap, the dshSection member will be NULL.

dsOffset

Specifies the offset to the bitmap’s bit values within the file mapping object referenced by dshSection. If dshSection is NULL, the dsOffset value has no meaning.
