GrayScale, but not Indexed?

[BCWGuy]

The ConvertTo8BppGrayScale method converts the image to an "8-bits gray-scaled palette", and when I save the file to a TIF format and open it in Photoshop it shows as an "Indexed Color", "8 bits/Channel" image.

But, I want to make a GrayScale image, so that in Photoshop it opens with 'Gray Scale' as the mode, and not 'Indexed Color'.

So how can I make a GrayScale image, instead of an 8-bit palette image made of all gray colors?

Hi,

You have to call fxGrayscale if you want to keep the initial bit-depth.

Kind regards,
