workbook   = WriteExcel.new("images.xls")
worksheet4 = workbook.add_worksheet('Image 1')
worksheet4.write('A10', "Image inserted over scaled rows and columns.")
worksheet4.insert_image('A1',
  File.join(File.dirname(File.expand_path(__FILE__)), '24bit.bmp')
)
workbook.close

while running above file I am getting following error :

".bmp isn't a 24bit true color bitmap. "

Used this to convert into true color bitmap

convert alarm.bmp -type truecolor 24bit.bmp

Help.
