Solution 1

Use

CreateFromArray (BYTE* pArray,DWORD dwWidth,DWORD dwHeight,DWORD dwBitsperpixel, DWORD dwBytesperline, bool bFlipImage)

to convert an existing binary representation of an image into a CxImage object.

DWORD dwBytesperline -> i am not sure about this parameter , please explain me.
i am using 8 bit image ( 1400 * 1024 ) - so how much it would come for DWORD dwBytesperline??

It's the number of bytes per line, just as the name suggests. In your case it is probably 1400. The parameter exists, because there are images that use slack bytes to fill up each line to multiple of 4 bytes or some other number. Hence the number of bytes per line is not always exactly the number of bytes per pixel times the number of pixels per line.
