why my vi cannot work?

[mmm2006]

I want to change rgb data to a white-black data and save to a bmp file.

But i don't know why my data cannot be output into bmp file, only black result.

even they can be seen by Draw Flattened Pixmap.vi.  Maybe miss somethng.

But i just don't know.

Anyone can help me about it?

my enviroment:labview 8.5. Format for bmp: h: 234,w:320.

thanks.

You need to define which colors to use.

Your VI will work if you wire a 2-element array of color constants (white and black in your case) to the color input of the Flatten Pixmap.vi.
