下面的程式可以正常的將影像顯示在電腦上
但他的方式好像是將影像放到記憶體裡
請問各位前輩
要如何將放在記憶體裡的frame抓出來做處理(如：兩值化、影像相減…等)
或者是直接存成檔案做處理
找了很多資料都找不到要怎麼對DIB做影像處理或者是存成檔案
請各位前輩給小弟些提點!

資料存在 m_pCurrent，在Callback函式內會把資料寫到這個成員變數內，裡面是一個陣列存放所有的資料，至於資料的內容格式則依據m_pBitmapInfo
參數來決定，請查閱MSDN有關BITMAPINFOHEADER的說明

你用的是哪一版MultiCam ,

新舊版有些差異喔...

To justdo:
您好~我知道資料是放在 m_pCurrent裡
但他好像只有資料，bmp的檔頭和調色盤是另外存在m_pBitmapInfo裡
請問我該怎麼將m_pBitmapInfo跟m_pCurrent合併
將其存成一張bmp的影像


To friendlly:
我不知道我是哪一版本的耶
這是我在用的multicam.h
