This class is used to create objects that contain information to describe pixel data for a rectangular area of bitmap images.

Syntax

class BitmapData {
  public:
    UINT        Width;
    UINT        Height;
    INT         Stride;
    PixelFormat PixelFormat;
    VOID*       Scan0;
    UINT_PTR    Reserved;
};

Data Members

• Width
  A UINT value specifying the width, in pixels, of the bitmap image area.

• Height
  A UINT value specifying the height, in pixels, of the bitmap image area.

• Stride
  An INT value specifying the number of bytes from one scan line of the bitmap area to the next.

  This value is negative for bottom-up bitmap images.

• PixelFormat
  A PixelFormat value specifying the image's pixel format.

• Scan0
  A VOID pointer to the beginning of the first scan line.
