Convert a 10 bit grayscale imag to color

Hi, all

    I am a 8-year labview experience programmer, but new to image procession or NI-Vision. And now I have come to a problem with image conversion.

    I have a image acquision board which acquires 1k*1k 10 bit grayscale image, I saved the acquired image into *.raw format (binary), and now I am required to convert these image into bmp (jpeg,png,or diff) format. When I try to use the "Imaq save 2" VI , I got a error saying something like "not supported image type". After searching this forum, it seems as if I should use a color-type image to save as the bmp format,but to receive my 10 bit raw data, I should first create a U16 Grayscale image. So how can I solve this problem?

Thanks for any suggestions!
