Within SingleFrameSample.cpp, the return value “length” of the function “GetQHYCCDMemLength” is 19702032, which is not equal to multiply the width(3584) of imge by the heigth(2574) of image. Why?

Because return image is 3 channel (RGB) or is 16bit(one pixel is two byte). So we use the 3*W*H for it.   And this is also why current SDK does not support 3channel and 16bit color image. Because it need 6*W*H

3 channel 8bit :  memory size is 3*w*h

1 channel 16bit: memory size is 2*w*h

1channel 8bit: memeory size is 1*w*h

3 channel 16bit: does not support in this SDK
