Hi Guys,

I meet a color problem when capture the images of object window. I
have a small program with 5 object windows and I use following codes
to change the color table and capture the display in the window

;call xloadct
xloadct, /modal, group = event.top

;get the changed color table
tvlct, R, G, B, /get

;change the palette object
opalette ->setProperty, red_values = R, green_values = g, blue_values
= b

;capture the window display
draw_id -> getProperty, image_data = data

If using BW color table, the captured screen image is correct,
otherwise, the color of the captured screen image is not correct. I
cannot figure out the problem. Any suggestions will be highly
appreciated.

Thanks,

Songtao
