[Insight-users] problem with RGB .bmp images

[John]

I'm getting .bmp files from an OCT device, which I segment then on converted
greyscale images.

The problem is, that I would like to apply the segmented borders to the original
colored images. But I can't even read the files in color format.

The below code doesn't work with the .bmp images from the OCT device, but with
other .bmp or rgb images such as jpeg, png the code works.
What could that be? Really mysterious.

Thanks in advance for any help.
