CreateFromArray quit working

Hi Davide First thanks for this software - its great! I was working with CxImage for couple of months, and it works great. In some point it quit. I call CreateFromArray and it does nothing to the object. GetLastError returns an empty string. What I’m doing is convert a buffer I get from my webcam to a jpeg image. I call this function on a callback function from the windows Video Capture. I did not change a thing in my code or linking. Here is the relevant part of the code: Code: LRESULT PASCAL FrameCallbackProc (HWND hWnd, LPVIDEOHDR lpVHdr) { /* Get the Format struct. */ int size = capGetVideoFormatSize (hWnd); char* format = new char [size]; capGetVideoFormat (hWnd, format, size); /* Make CxImage from the buffer received from webcam driver.*/ CxImage image; image.CreateFromArray ((BYTE*)lpVHdr->lpData, ((BITMAPINFO*)format)->bmiHeader.biWidth, ((BITMAPINFO*)format)->bmiHeader.biHeight, ((BITMAPINFO*)format)->bmiHeader.biBitCount, ((BITMAPINFO*)format)->bmiHeader.biWidth * ((BITMAPINFO*)format)->bmiHeader.biBitCount / 8, FALSE); ... I do not think the problem is with CxImage but I probably changed some thing in the system. I don't know what. Did you bump into this problem in the past? Any lead will be most appreciated Thanks Erez Bibi http://dcru-server.com

Found the problem
The BitPerPixel was set to 12 I had to set it to 24 and set the compression to None.
