Dear Dr. Fanning,

I write the captured screen images to a bmp file and when I look at
the bmp file, I found the color is not what it looks like on the
screen.

It is just a simple widget program, with several object graphic
windows, each display an image and ROIs(draw with plot object).

Followings are the codes to capture the screen display and write them
to the disk

;capture the window display
draw_id -> getProperty, image_data = data
;write to file
write_bmp, filename, data

Thank,

Songtao
