我打錯了，是vs2008！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！vs2008vs2008vs2008vs2008vs2008vs2008vs2008vs2008vs2008

編譯選項加/EP /P，重新編譯，查看宏展開后對應的.i文件。
#5
你的image模版沒有widthStep和imageData函數，你是不是copy漏了什么東西？你這個模板只能用於uchar類型當數據，應該是默認模版，應該是漏了另外一個模板。
#6
// /* get the width of an image. */ int width() const { return w; } // /* get the height of an image. */int height() const { return h; }//
這里不是？還是，求指導啊，要自己加上的話，怎么寫
#7
錯誤提示很明顯，是你的image里沒有imageData成員，你看看你的image類
#8
code=c]/* use imPtr to get pointer to image data. */#define imPtr(im, x, y) &(((uchar *)(im->imageData+y*im->widthStep))[x])
[/code]
#9
我重新改了一下，又成這樣了，求指導啊

這是別人的全局轉換函數，是轉換iamge內部數據類型的，和你之前出錯的地方沒有半毛錢關系。你要參考別人的東西你就參考全套代碼。你要改別人的東西你也要看懂了再改。你少copy了幾個代碼文件，自己也沒搞懂模板編程。很難教得明你。
