IuImageEx

class IuImageEx : public IuUnknown
{
public:
    virtual BOOL    Create( int nWidth, int nHeight, int nBPP = 16) = 0;

    virtual BYTE*   Data(void) = 0; 

    virtual UINT    Height() = 0;
    virtual void    Height(UINT nHeight) = 0;

    virtual UINT    Width() = 0;
    virtual void    Width(UINT nWidth) = 0;

    virtual UINT    BitCount() = 0;
    virtual void    BitCount(UINT nBitCount) = 0;

    virtual COLORREF GetPixel( int x, int y) = 0;
};

圖型編碼太多種, 但實際使用時, 也只有用到部份函式, 整個拉出介面時, 才發現用到的不多!
