Sathish,
           It seems it is reading and verifying bitmap planes and bpp data by the following method

data.unpack("x26 v2")

The value return by this method should be 24. This is nothing but bitcount(they were calling like this).

So please check the above method is returning 24. If the value of bitcount is 24 then the error will never come.

Regards,
Manivannan

)
workbook.close

I am not able to write bitmap image whereas I can import .jpg images well.

Error i am getting
"isn't a 24bit true color bitmap."

Also used this step to convert into true color bitmap
"convert alarm.bmp -type truecolor 24bit.bmp"

Help..
