Reading 32-bit BMP (with an alpha channel) in IDL [message #70027]

I have a set of BMP images I need to read in. They have 4 channels,
red, green, blue and alpha. Every commercial image viewer I have can
open them, including matlab. Now, I could go to the trouble to
convert them to 24-bit or another image format, but why should I
change? IDL should be able to read this standard input. Read_bmp.pro
explicitly states that it can only read 24-bit. Is there something
built-in I'm not seeing? Is there a coyote function that already does
it?
