CCImage在"CCImage.h"中定義，表示一張載入到記憶體的紋理圖片。在其內部的實現中，紋理以每個畫素的顏色值儲存在記憶體之中。CCImage通常作為檔案和顯示卡間資料交換的一個工具，因此主要提供了兩個方面的功能：一方面是檔案的載入與儲存，另一方面是記憶體緩衝區的讀寫。

我們可以使用CCImage輕鬆地讀寫圖片檔案。目前，CCImage支援PNG、JPEG和TIFF三種主流的圖片格式。下面列舉與檔案讀寫相關的方法：

  /** 
    @brief  Load the image from the specified path. 
    @param strPath   the absolute file path
    @param imageType the type of image, now only support tow types.
    @return  true if load correctly
    */
    bool initWithImageFile(const char * strPath, EImageFormat imageType = kFmtPng);

    /*
     @brief The same meaning as initWithImageFile, but it is thread safe. It is casued by
            loadImage() in CCTextureCache.cpp.
     @param fullpath  full path of the file   
     @param imageType the type of image, now only support tow types.
     @return  true if load correctly
     */
    bool initWithImageFileThreadSafe(const char *fullpath, EImageFormat imageType = kFmtPng);
 

    /**
    @brief    Save the CCImage data to specified file with specified format.
    @param    pszFilePath        the file's absolute path, including file subfix
    @param    bIsToRGB        if the image is saved as RGB format
    */
    bool saveToFile(const char *pszFilePath, bool bIsToRGB = true);
 

    unsigned char *   getData()               { return m_pData; }
    int         getDataLen()            { return m_nWidth * m_nHeight; }

    /**
    @brief  Load image from stream buffer.

    @warning kFmtRawData only support RGBA8888
    @param pBuffer  stream buffer that hold the image data
    @param nLength  the length of data(managed in byte)
    @param nWidth, nHeight, nBitsPerComponent are used for kFmtRawData
    @return true if load correctly
    */
    bool initWithImageData(void * pData, 
                           int nDataLen, 
                           EImageFormat eFmt = kFmtUnKnown,
                           int nWidth = 0,
                           int nHeight = 0,
                           int nBitsPerComponent = 8);
