Hi!!

I have a black&white tiff image. 
I read this image with TIFFReadScanline and I show
pixels value, I obtain values since 0 until 255. I
don't know why because like I have said before is a
black&white image.

I have opened the image with the GIMP and I have seen
that the image was in grey-scale, then I have saved it
as RGB image.

I have read this last image with TIFFReadScanline and
now the pixels value are 0 or 255, that it's ok
because the image always has been a black&white image.

Is there a method that converts a grey-scale image to
RGB image?

I have to do this process with a lot of images, so I
want to automatize this process.

Thanks a lot, 

Mary
