Cause the image file contains two parts: file header and data, you can not split the file direct-file-division.

It is recommand to use the API in NI-Vision module.

above problem has solved! Thank you very much! Now, I want to make the pixel matrix display  in fixed position of  'image display'!n other words,I hope the first line data show at the bottum of 'image display' , and the second will on the top of the first in 'image display'. The rest can be done in the same manner.

I have set the size of 'image display'.  how to set the size of the pixel? And how to make the particular pixel  display in certain positions of the image ?If a pixel position is set ,the pixel position of the whole image also are sure, is it right? This method is feasible?Do you have any good idea?
